Abstract
There are limited tools for adapting coronavirus disease 2019 (COVID-19) infection control plans to school settings. We present an infection prevention model for optimizing safe re-opening for elementary and secondary schools during the global COVID-19 pandemic and review the current evidence behind various infection prevention interventions in school settings. The model is adapted from the Centers for Disease Control and Prevention fundamental pillars for infection prevention and includes 4 categories of intervention: epidemiologic controls (town prevalence metrics, diagnostic testing, quarantine strategies), administrative controls (state vaccination policies, alternative school models, symptom screens, quarantine breaks), engineering/environmental controls (distancing, outdoor space, ventilation), and personal protective equipment (PPE)/hand hygiene (face coverings, hand sanitizing). The adapted infection control pillars model utilizes implementation science–informed considerations to maximize pragmatism and adherence by leveraging evidence-based strategies. It highlights the necessity of redundant infection prevention interventions, acknowledges the importance of community buy-in to achieve real-world effectiveness, and addresses tactics to overcome implementation barriers. Recommendations are grounded in the Dynamic Sustainability Framework and include suggestions to maintain infection prevention effectiveness over time to ensure ongoing safety.

JOURNAL OF THE EGYPTIAN PUBLIC HEALTH ASSOCIATION 2022; 97:6. [PMID: 35133535 PMCID: PMC8823197 DOI: 10.1186/s42506-021-00094-x] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/23/2021] [Accepted: 10/28/2021] [Indexed: 01/06/2023]
Abstract
Abstract
Background
In the global health emergency caused by COVID-19, multiple experts have mandated the use of hand sanitizers as a safety measure from COVID-19. The sale of hand sanitizers has increased many folds. Therefore, when there is such large use of hand sanitizers, it becomes extremely important to study and understand hand sanitizers in a comprehensive manner.
Main body of the abstract
This article starts with the importance of sanitizers as a defence mechanism that is employed by the hand to fight against the coronavirus. This article provides information about history, types, composition, various dosage forms, and marketed formulations of hand sanitizers. The article sheds a detailed light on industrial production techniques for hand sanitizers and also outlines new innovative techniques that were employed by the industry to mass produce hand sanitizers in the wake of the pandemic. The article further dives into a comparison between hand sanitizers and soaps so as to give pros and cons of the use of soap against the use of hand sanitizers. One of the aims of the article is to study the side effects of sanitizers so as to develop a cautious approach while using hand sanitizers and therefore a comprehensive list of side effects of the use of hand sanitizers is given.
Conclusion
The review article finds that hand sanitizers are extremely efficient in fight the virus but along with it, it brings along arrange of risks which are outlined in the article.

Abstract
BACKGROUND Diarrhoea accounts for 1.8 million deaths in children in low- and middle-income countries (LMICs). One of the identified strategies to prevent diarrhoea is hand washing. OBJECTIVES To assess the effects of hand-washing promotion interventions on diarrhoeal episodes in children and adults. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, nine other databases, the World Health Organization (WHO) International Clinical Trial Registry Platform (ICTRP), and metaRegister of Controlled Trials (mRCT) on 8 January 2020, together with reference checking, citation searching and contact with study authors to identify additional studies. SELECTION CRITERIA Individually-randomized controlled trials (RCTs) and cluster-RCTs that compared the effects of hand-washing interventions on diarrhoea episodes in children and adults with no intervention. DATA COLLECTION AND ANALYSIS Three review authors independently assessed trial eligibility, extracted data, and assessed risks of bias. We stratified the analyses for child day-care centres or schools, community, and hospital-based settings. Where appropriate, we pooled incidence rate ratios (IRRs) using the generic inverse variance method and a random-effects model with a 95% confidence interval (CI). We used the GRADE approach to assess the certainty of the evidence. MAIN RESULTS We included 29 RCTs: 13 trials from child day-care centres or schools in mainly high-income countries (54,471 participants), 15 community-based trials in LMICs (29,347 participants), and one hospital-based trial among people with AIDS in a high-income country (148 participants). All the trials and follow-up assessments were of short-term duration. Hand-washing promotion (education activities, sometimes with provision of soap) at child day-care facilities or schools prevent around one-third of diarrhoea episodes in high-income countries (incidence rate ratio (IRR) 0.70, 95% CI 0.58 to 0.85; 9 trials, 4664 participants, high-certainty evidence) and may prevent a similar proportion in LMICs, but only two trials from urban Egypt and Kenya have evaluated this (IRR 0.66, 95% CI 0.43 to 0.99; 2 trials, 45,380 participants; low-certainty evidence). Only four trials reported measures of behaviour change, and the methods of data collection were susceptible to bias. In one trial from the USA hand-washing behaviour was reported to improve; and in the trial from Kenya that provided free soap, hand washing did not increase, but soap use did (data not pooled; 3 trials, 1845 participants; low-certainty evidence). Hand-washing promotion among communities in LMICs probably prevents around one-quarter of diarrhoea episodes (IRR 0.71, 95% CI 0.62 to 0.81; 9 trials, 15,950 participants; moderate-certainty evidence). However, six of these nine trials were from Asian settings, with only one trial from South America and two trials from sub-Saharan Africa. In seven trials, soap was provided free alongside hand-washing education, and the overall average effect size was larger than in the two trials which did not provide soap (soap provided: RR 0.66, 95% CI 0.58 to 0.75; 7 trials, 12,646 participants; education only: RR 0.84, 95% CI 0.67 to 1.05; 2 trials, 3304 participants). There was increased hand washing at major prompts (before eating or cooking, after visiting the toilet, or cleaning the baby's bottom) and increased compliance with hand-hygiene procedure (behavioural outcome) in the intervention groups compared with the control in community trials (data not pooled: 4 trials, 3591 participants; high-certainty evidence). Hand-washing promotion for the one trial conducted in a hospital among a high-risk population showed significant reduction in mean episodes of diarrhoea (1.68 fewer) in the intervention group (mean difference -1.68, 95% CI -1.93 to -1.43; 1 trial, 148 participants; moderate-certainty evidence). Hand-washing frequency increased to seven times a day in the intervention group versus three times a day in the control arm in this hospital trial (1 trial, 148 participants; moderate-certainty evidence). We found no trials evaluating the effects of hand-washing promotions on diarrhoea-related deaths or cost effectiveness. AUTHORS' CONCLUSIONS Hand-washing promotion probably reduces diarrhoea episodes in both child day-care centres in high-income countries and among communities living in LMICs by about 30%. The included trials do not provide evidence about the long-term impact of the interventions.

Abstract
This study was aimed to produce and characterize the first commercial glass materials with enhanced antibacterial property using conventional melting method. For this purpose, typical container glass composition that contains some specific metal ions, such as silver, strontium, and copper, was used to obtain antibacterial glass samples using classical melting method. After the melting process, antibacterial tests and migration tests were applied to the glasses, and it was found that the glass doped with 2% Ag2O was the best composition. X-rays diffractometer (XRD), thermal expansion coefficient, density, refractive index, hardness, and elastic module results showed that the glass doped with 2% Ag2O was a suitable material as a container glass. High Temperature Melting Observation System studies were performed on the produced antibacterial glass composition, and it was found that the antibacterial glass can be produced in soda lime glass furnaces without changing any furnace design and production parameters. As a result of the characterization studies, it was concluded that the produced container glass doped with silver can be a good candidate for food and pharmaceutical products where bacterial growth is absolutely undesirable.

Abstract
BACKGROUND Congenital cytomegalovirus infection is the most common nongenetic cause of sensorineural hearing loss in childhood and an important cause of neurodisability. There is no licensed cytomegalovirus (CMV) vaccine and no antenatal treatment for congenital CMV that is routinely recommended in clinical practice in the United Kingdom. OBJECTIVES To review the published literature for studies that evaluated preventative hygiene-based interventions in pregnancy for their impact on knowledge about CMV prevention, the uptake of preventative behaviors or the acquisition of CMV in pregnancy. SEARCH STRATEGY Searches were carried out in Medical Literature Analysis and Retrieval System Online and Cumulative Index of Nursing and Allied Health Literature databases. SELECTION CRITERIA All human studies, limited to women of childbearing age were included. DATA COLLECTION AND ANALYSIS Two reviewers independently assessed the quality of the methods and results of included articles. Extracted data were classified using Cochrane guidelines. MAIN RESULTS Seven studies met the inclusion criteria. These show that preventative measures are acceptable to pregnant women, can impact their behavior and have the potential to reduce CMV in pregnancy. They are limited by several factors; sample size, nonrandomized trial design and interventions that are beyond routine clinical practice. CONCLUSIONS An effective intervention that changes behavior in pregnancy and reduces the risk of CMV acquisition is needed as part of routine care. There is currently insufficient evidence about the form that this intervention should take. REGISTRATION PROSPERO registration number: CRD42017069666.

Abstract
In the United States, lack of proper handwashing is associated with respiratory and gastrointestinal illnesses. Interventions to improve handwashing practices have led to an increase in handwashing knowledge and behavior, and decreases in gastrointestinal illnesses. Most studies have evaluated their interventions in the context of reported handwashing rates by observation, reduction of illnesses, as well as reduced absences, however none of these studies examined handwashing quality or knowledge as outcome measures. The objective of this paper is to present the results from a handwashing program with a special focus on the evaluation methods. A pre-post design was used to evaluate a handwashing program that took place in two pre-schools the northeast of the United States. The program utilized a black light technology to demonstrate to children the importance of good quality. The evaluation consisted of assessing knowledge and quality of handwashing using a linear puzzle and individual handwashing observation, respectively. Students from both schools improved on both knowledge and quality over time (p-values 0.071 and <0.001, respectively). The present study demonstrates that the use of black light technology as an educational tool may help to improve handwashing quality among pre-school aged children, even after only one instructional session.

Abstract
BACKGROUND Absenteeism amongst pre-school children is often due to illnesses such as hand, foot, and mouth disease, acute gastroenteritis, cold and flu, which are easily spread amongst them. This is because of weak immunity and lack of knowledge on proper hand hygiene. This quasi-experimental study assessed the efficacy of an intervention consisting of a hand hygiene education programme, along with digital tools in bringing about a change in behaviour and health conditions amongst pre-school children in Klang Valley, Malaysia. METHODS A total of 377 school children, male and female, aged 5-6 years old, participated and were assigned to either the intervention or a control group. During the 2 months intervention period, children in the test group were trained on proper hand hygiene practices and techniques with the aid of the interactive android-based tablets. The numbers of absent days of all the children were recorded for 2 months before the intervention and during the intervention. RESULTS In the test group, there was a 25% increase in the total number of absent days from the pre-intervention period to the intervention period, a much lesser increment observed as compared to that of control group in which the increase was much higher at 89%. Results showed a significant difference (P < 0·05) between the absenteeism rates for the test and control group during the intervention period. CONCLUSION These results suggest that proper education and intervention increase hand hygiene compliance, which may help decrease school absenteeism due to illness; however, a longer study duration may be necessary to evaluate the benefit further.

Abstract
BACKGROUND Handwashing prevalence in schools in Kenya is low due to lack of access to water and soap and lack of drive for handwashing. Soapy water made from detergent powder is an inexpensive alternative to bar soap and disgust and social norms change can be powerful drivers of handwashing, but their effectiveness has not been assessed in school setting. In Kenyan public schools, we evaluated an equipment-behavior change intervention's effect on handwashing outcomes. We also monitored functionality of the Povu Poa prototypes to identify design improvements necessary for continued high usage in institutional settings. METHODS The intervention included the "Povu Poa", a new type of handwashing station that dispensed foaming soap and rinse water, combined with school-wide behavior change promotion based on disgust and social norms. In this stepped-wedge cluster-randomized trial, we randomly selected 30 schools and divided them into 3 groups of 10. Following baseline data collection, we delivered the intervention sequentially (Group 1: 3-5 weeks after baseline; Group 2: 6-8 weeks; Group 3: 19-24 weeks). We observed outcomes [1] availability of handwashing materials at handwashing places, and; 2) observed handwashing behavior after toilet use among schoolchildren) at baseline and in three follow-up rounds. We compared the outcomes between schools that had received the intervention and schools that had not yet received the intervention. RESULTS Water and soap/soapy water were available at 2% of school visits before intervention, and at 42% of school visits after intervention.. Before intervention, we observed handwashing with water after 11% of 461 toilet use events; no one was observed to wash hands with soap/soapy water. After intervention, we observed handwashing after 62% of 383 toilet use events (PR = 5.96, 95% CI = 3.02, 11.76) and handwashing with soap/soapy water after 26% of events (PR incalculable). Foaming soap dispenser caps were cracked in 31% of all observations, but were typically still functional. CONCLUSIONS Our combined equipment-behavior intervention increased availability of handwashing materials and improved the compliance with handwashing after using the toilet, but handwashing with soap was still rare. Equipment durability must be improved for deployment in schools at scale.

Abstract
Millions of dollars have been spent on the design and dissemination of educational materials to improve handwashing to prevent infectious diseases. School-age children have been the focus of many of these efforts; yet little is known about the content of these materials. This study uses content analysis to examine the theoretical and motivational trends as well as the communication approach used in a sample of hand hygiene intervention materials targeting elementary-age children. Two trained coders analyzed 144 communication materials. Study results indicate that educational materials infrequently exhibit information consistent with theories of communication for behavior change, commonly use fear-based messaging, and rarely recommend using technology in the design of the interventions. Implications for future research and the design of more strategic, child-focused hand hygiene interventions are discussed.

Abstract
BACKGROUND Infectious illness in the workplace places a substantial cost burden on employers due to productivity losses from employee absenteeism and presenteeism. AIM Given the clear impacts of infectious illness on workplaces, this review aimed to investigate the international literature on the effectiveness and cost-benefit of the strategies non-healthcare workplaces use to prevent and control infectious illnesses in these workplaces. METHODS MEDLINE, CINAHL Plus with Fulltext and Business Source Complete were searched concurrently using EBSCO Host 1995-2016. FINDINGS Infection prevention and control strategies to reduce workplace infectious illness and absenteeism evaluated in the literature include influenza vaccination programs, use of alcohol-based hand sanitiser and paid sick days. While the reported studies have various methodological flaws, there is good evidence of the effectiveness of influenza vaccination in preventing workplace infectious illness and absences and moderate evidence to support hand hygiene programs. DISCUSSION Some studies used more than one intervention concurrently, making it difficult to determine the relative benefit of each individual strategy. Workplace strategies to prevent and control infectious illness transmission may reduce costs and productivity losses experienced by businesses and organisations related to infectious illness absenteeism and presenteeism.

Abstract
BACKGROUND Previous school-based hand hygiene interventions have reported to successfully reduce infectious illness among schoolchildren. But few studies have tested the effect in large populations with adequate statistical power and analyses. The aim of this study was to evaluate whether a school-based multicomponent intervention to improve handwashing among schoolchildren, the Hi Five study, succeeded in reducing infectious illness and illness-related absenteeism in schools. METHODS The Hi Five study was a three-armed cluster-randomized controlled trial involving 43 randomly selected Danish schools; two intervention arms involving 14 schools each, and 15 control schools. Infectious illness days, infectious illness episodes and illness-related absenteeism were estimated in multilevel regressions, based on available cases of text messages answered by parents and based on questionnaire data reported by schoolchildren, respectively. RESULTS At follow-up, children in the intervention schools did not differ from the control schools in number of illness days [odds ratio (OR)I-arm I: 0.91 (0.77-1.07) and ORI-arm II: 0.94 (0.79-1.12)] and illness episodes [ORI-arm I: 0.95 (0.81-1.11) and ORI-arm II: 0.98 (0.84-1.16)] or in reporting illness-related absenteeism [ORI-arm I: 1.09 (0.83-1.43) & ORI-arm II: 1.06 (0.81-1.40)]. CONCLUSIONS The multicomponent Hi Five intervention achieved no difference in the number of illness days, illness episodes or illness-related absenteeism among children in intervention schools compared with control schools. It is noteworthy that one of the main components in the intervention, a mandatory daily handwashing before lunch, was only implemented by 1 of 3 of teachers in intervention schools.

Abstract
Hygiene procedures for hands, surfaces and fabrics are central to preventing spread of infection in settings including healthcare, food production, catering, agriculture, public settings, and home and everyday life. They are used in situations including hand hygiene, clinical procedures, decontamination of environmental surfaces, respiratory hygiene, food handling, laundry hygiene, toilet hygiene and so on. Although the principles are common to all, approaches currently used in different settings are inconsistent. A concern is the use of inconsistent terminology which is misleading, especially to people we need to communicate with such as the public or cleaning professionals. This paper reviews the data on current approaches, alongside new insights to developing hygiene procedures. Using this data, we propose a more scientifically-grounded framework for developing procedures that maximize protection against infection, based on consistent principles and terminology, and applicable across all settings. A key feature is use of test models which assess the state of surfaces after treatment rather than product performance alone. This allows procedures that rely on removal of microbes to be compared with those employing chemical or thermal inactivation. This makes it possible to ensure that a consistent "safety target level" is achieved regardless of the type of procedure used, and allows us deliver maximum health benefit whilst ensuring prudent usage of antimicrobial agents, detergents, water and energy.

Am J Infect Control 2017; 45:682-689. [PMID: 28242074 DOI: 10.1016/j.ajic.2017.01.018] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2016] [Revised: 01/16/2017] [Accepted: 01/17/2017] [Indexed: 12/15/2022]
Abstract
BACKGROUND Hand-hygiene interventions are widely used in schools but their effect on reducing absenteeism is not well known. METHODS The aim of our literature review was to determine whether implementation of a hand-hygiene intervention reduced infectious disease-associated absenteeism in elementary schools. The eligible studies (N = 19), published between 1996 and 2014, were summarized and the methodologic quality of each was assessed. RESULTS Our review indicated evidence is available to show hand-hygiene interventions had an effect on reducing acute gastrointestinal illness-associated absenteeism but inadequate evidence is available to show an effect on respiratory illness-associated absenteeism. CONCLUSIONS The methodologic quality assessment of eligible studies revealed common design flaws, such as lack of randomization, blinding, and attrition, which must be addressed in future studies to strengthen the evidence base on the effect of hand-hygiene interventions on school absenteeism.

Abstract
Background Hand hygiene is known to be effective in preventing hospital and community-acquired infections. The increasing number of hand sanitizer brands in Kenyan hospitals and consumer outlets is of concern. Thus the main aim of this study was to evaluate the anti-bacterial efficacy and organoleptic properties of these hand sanitizers in Kenya. Methods This was an experimental, laboratory-based study of 14 different brands of hand sanitizers (coded HS1-14) available in various retail outlets and hospitals in Kenya. Efficacy was evaluated using standard non-pathogenic Escherichia coli (ATCC 25922), Staphylococcus aureus (ATCC 25923) and Pseudomonas aeruginosa (ATCC 27853) as per the European Standard (EN). The logarithmic reduction factors (RF) were assessed at baseline and after treatment, and log reduction then calculated. Ten and 25 healthy volunteers participated in the efficacy and organoleptic studies respectively. Results Four (28.6%) hand sanitizers (HS12, HS9, HS13 and HS14) showed a 5.9 reduction factor on all the three bacteria strains. Seven (50%) hand sanitizers had efficacies of <3 against all the three bacteria strains used. Efficacy on E. Coli was higher compared to the other pathogens. Three hand sanitizers were efficacious on one of the pathogens and not the other. In terms of organoleptic properties, gel-based formulations were rated far higher than the liquid based formulations brands. Conclusion Fifty percent (50%) of the selected hand sanitizers in the Kenyan market have efficacy that falls below the World Health Organization (WHO) and DIN EN 1500:2013. Of the 14 hand sanitizers found in the Kenyan market, only four showed efficacies that were comparable to the WHO-formulation. There is a need to evaluate how many of these products with <3 efficacy that have been incorporated into the health system for hand hygiene and the country’s policy on regulations on their usage.

Abstract
BACKGROUND We assessed the effectiveness of a handwashing program using hand sanitizer to prevent school absenteeism due to upper respiratory infections (URIs). METHODS This was a randomized, controlled, and open study on a sample of 1341 children 4-12 years old, attending 5 state schools in Almería (Spain), with an 8-month follow-up. The experimental group (EG) washed their hands with soap and water, together with using hand sanitizer, and the control group followed their usual handwashing procedures. Absenteeism rates due to URIs were compared between the 2 groups through a multivariate Poisson regression analysis. The percent of days missed in both groups were compared with a z test. RESULTS Overall, 1271 cases of school absenteeism due to URIs were registered. Schoolchildren from the EG had a 38% lower risk of absenteeism due to URIs, incidence rate ratio: 0.62, 95% confidence interval: 0.55-0.70, and a decrease in absenteeism of 0.45 episodes/child/academic year, p < .001. Pupils missed 2734 school days due to URIs and the percentage of days absent was significantly lower in the EG, p < .001. CONCLUSIONS Use of hand sanitizer plus handwashing with soap accompanied by educational support is an effective measure to reduce absenteeism due to URIs.

Abstract
Hand washing is the most effective way to prevent the spread of communicable disease. The purpose of this double-blind, placebo-controlled study was to assess whether an alcohol-free, instant hand sanitizer containing surfactants, allantoin, and benzalkonium chloride could reduce illness absenteeism in a population of 769 elementary school children and serve as an effective alternative when regular soap and water hand washing was not readily available. Prior to the study, students were educated about proper hand washing technique, the importance of hand washing to prevent transmission of germs, and the relationship between germs and illnesses. Children in kindergarten through the 6th grade (ages 5–12) were assigned to the active or placebo hand-sanitizer product and instructed to use the product at scheduled times during the day and as needed after coughing or sneezing. Data on illness absenteeism were tracked. After 5 weeks, students using the active product were 33% less likely to have been absent because of illness when compared with the placebo group.

Abstract
The purpose of this project was to determine if a multiple-week learner-centered hand washing program could improve hand hygiene behaviors of 2nd-graders in a northern Illinois public school system. Volunteers from the Rockford Hand Washing Coalition went into 19 different classrooms for 4 consecutive weeks and taught a learner-centered program. The program consisted of interactive class discussions and activities using GlitterBug®training devices and agar plate materials. A one-factor repeated measure analysis of variance indicated a statistically significant 34% decrease in the absenteeism rate for students in the intervention group. Chi-square analyses on agar plate data indicated that students had cleaner hands after washing. Qualitative data from parents and teachers indicated that a majority of the students were engaging in hand-washing behavior. These results indicate that integrating a learner-centered interactive program in a multiple-week structure can lead to improvement in hand hygiene behavior.

Abstract
Young schoolchildren are recognised as being at particular risk of contracting and transmitting enteric infection. (Finn and Crook, 1998/1999). A collaborative infection control programme was designed, piloted and evaluated in six primary schools in conjunction with the local authority's public protection and education departments and the local health protection team. These pilots helped to inform the programme rolled out to all primary and special needs schools during 2002 to 2003. A baseline sanitation survey was undertaken with the scores used to prioritise schools for infection control audits. High priority schools were audited. Medium and low priority schools were sent self-assessment packs, the results of which were subsequently validated. Risks were communicated to each school at the time of visit with a follow-up written report. All schools received advice and support on infection control, including recommendations for improvements, updated policies and supporting educational materials. Key findings from the programme were lack of adequate facilities for handwashing such as soap, paper towels and hot water; ineffective cleaning programmes and working practices, including awareness of Control of Substances Hazardous to Health (COSHH) (1999) and waste disposal. Infection control guidelines have been produced for schools, together with an ongoing programme of infection control follow-up audits.

Abstract
Hands can be a vector for transmitting pathogenic microorganisms to foodstuffs and drinks, and to the mouths of susceptible hosts. Hand washing is the primary barrier to prevent transmission of enteric pathogens via cross-contamination from infected persons. Conventional hand washing involves the use of water, soap, and friction to remove dirt and microorganisms. The availability of hand sanitizing products for use when water and soap are unavailable has increased in recent years. The aim of this systematic review was to collate scientific information on the efficacy of hand sanitizers compared with washing hands with soap and water for the removal of foodborne pathogens from the hands of food handlers. An extensive literature search was carried out using three electronic databases: Web of Science, Scopus, and PubMed. Twenty-eight scientific publications were ultimately included in the review. Analysis of this literature revealed various limitations in the scientific information owing to the absence of a standardized protocol for evaluating the efficacy of hand products and variation in experimental conditions. However, despite conflicting results, scientific evidence seems to support the historical skepticism about the use of waterless hand sanitizers in food preparation settings. Water and soap appear to be more effective than waterless products for removal of soil and microorganisms from hands. Alcohol-based products achieve rapid and effective inactivation of various bacteria, but their efficacy is generally lower against nonenveloped viruses. The presence of food debris significantly affects the microbial inactivation rate of hand sanitizers.

Abstract
OBJECTIVE The aim of this study was to determine the efficacy of a multimodal hand hygiene intervention program in reducing health care insurance claims for hygiene preventable infections (eg, cold and influenza), absenteeism, and subjective impact on employees. METHODS A 13.5-month prospective, randomized cluster controlled trial was executed with alcohol-based hand sanitizer in strategic workplace locations and personal use (intervention group) and brief hand hygiene education (both groups). Four years of retrospective data were collected for all participants. RESULTS Hygiene-preventable health care claims were significantly reduced in the intervention group by over 20% (P < 0.05). Absenteeism was positively impacted overall for the intervention group. Employee survey data showed significant improvements in hand hygiene behavior and perception of company concern for employee well-being. CONCLUSION Providing a comprehensive, targeted, yet simple to execute hand hygiene program significantly reduced the incidence of health care claims and increased employee workplace satisfaction.

Abstract
Background: To evaluate the antimicrobial efficacy of four different hand sanitizers against Staphylococcus aureus, Staphylococcus epidermidis, Pseudomonas aeruginosa, Escherichia coli, and Enterococcus faecalis as well as to assess and compare the antimicrobial effectiveness among four different hand sanitizers. Materials and Methods: The present study is an in vitro study to evaluate antimicrobial efficacy of Dettol, Lifebuoy, PureHands, and Sterillium hand sanitizers against clinical isolates of the aforementioned test organisms. The well variant of agar disk diffusion test using Mueller-Hinton agar was used for evaluating the antimicrobial efficacy of hand sanitizers. McFarland 0.5 turbidity standard was taken as reference to adjust the turbidity of bacterial suspensions. Fifty microliters of the hand sanitizer was introduced into each of the 4 wells while the 5th well incorporated with sterile water served as a control. This was done for all the test organisms and plates were incubated in an incubator for 24 h at 37C. After incubation, antimicrobial effectiveness was determined using digital caliper (mm) by measuring the zone of inhibition. Results: The mean diameters of zones of inhibition (in mm) observed in Group A (Sterillium), Group B (PureHands), Group C (Lifebuoy), and Group D (Dettol) were 22 ± 6, 7.5 ± 0.5, 9.5 ± 1.5, and 8 ± 1, respectively. Maximum inhibition was found with Group A against all the tested organisms. Data were statistically analyzed using analysis of variance, followed by post hoc test for group-wise comparisons. The difference in the values of different sanitizers was statistically significant at P < 0.001. Conclusion: Sterillium was the most effective hand sanitizer to maintain the hand hygiene.

Abstract
OBJECTIVE To spread knowledge and instigate the health professional to give advice on childcare during travels and on child transport safety. SOURCES OF DATA Literature review through the LILACS and MEDLINE(®) databases, using the terms: travel, safety, protective equipment, child, preventive medicine, retrieving articles published in the last 21 years. SUMMARY OF THE FINDINGS The authors analyzed 93 articles, of which 66 met the inclusion criteria after summaries were read. For drafting this article, the following sub-themes were proposed: getting ready to travel with children; knowing some of the transfer risks (air, land and water transportation) and exploring the destination with children (sun exposure, accommodations, altitude, food, traveler's diarrhea, insect bites) and return from the trip with children. CONCLUSIONS Over the years, there has been an increase in the number of children who travel around the world. However, this population is still subject to health problems while traveling and may be even more susceptible than the adult age group. These problems arise from a variety of factors, including exposure to infectious organisms, the use of certain types of transportation, and participation in some activities, such as hiking at high altitudes, among others. However, when traveling with children, these risk factors can be overlooked; a trip that is considered safe for an adult might not be a good choice for this age group. The pediatric consultation should be a good opportunity to optimize preventive guidelines at the pre-trip planning.

Abstract
BACKGROUND Diarrhoea accounts for 1.8 million deaths in children in low- and middle-income countries (LMICs). One of the identified strategies to prevent diarrhoea is hand washing. OBJECTIVES To assess the effects of hand washing promotion interventions on diarrhoeal episodes in children and adults. SEARCH METHODS We searched the Cochrane Infectious Diseases Group Specialized Register (27 May 2015); CENTRAL (published in the Cochrane Library 2015, Issue 5); MEDLINE (1966 to 27 May 2015); EMBASE (1974 to 27 May 2015); LILACS (1982 to 27 May 2015); PsycINFO (1967 to 27 May 2015); Science Citation Index and Social Science Citation Index (1981 to 27 May 2015); ERIC (1966 to 27 May 2015); SPECTR (2000 to 27 May 2015); Bibliomap (1990 to 27 May 2015); RoRe, The Grey Literature (2002 to 27 May 2015); World Health Organization (WHO) International Clinical Trial Registry Platform (ICTRP), metaRegister of Controlled Trials (mRCT), and reference lists of articles up to 27 May 2015. We also contacted researchers and organizations in the field. SELECTION CRITERIA Individually randomized controlled trials (RCTs) and cluster-RCTs that compared the effects of hand washing interventions on diarrhoea episodes in children and adults with no intervention. DATA COLLECTION AND ANALYSIS Three review authors independently assessed trial eligibility, extracted data, and assessed risk of bias. We stratified the analyses for child day-care centres or schools, community, and hospital-based settings. Where appropriate, incidence rate ratios (IRR) were pooled using the generic inverse variance method and random-effects model with 95% confidence intervals (CIs). We used the GRADE approach to assess the quality of evidence. MAIN RESULTS We included 22 RCTs: 12 trials from child day-care centres or schools in mainly high-income countries (54,006 participants), nine community-based trials in LMICs (15,303 participants), and one hospital-based trial among people with acquired immune deficiency syndrome (AIDS) (148 participants).Hand washing promotion (education activities, sometimes with provision of soap) at child day-care facilities or schools prevents around one-third of diarrhoea episodes in high income countries (rate ratio 0.70; 95% CI 0.58 to 0.85; nine trials, 4664 participants, high quality evidence), and may prevent a similar proportion in LMICs but only two trials from urban Egypt and Kenya have evaluated this (rate ratio 0.66, 95% CI 0.43 to 0.99; two trials, 45,380 participants, low quality evidence). Only three trials reported measures of behaviour change and the methods of data collection were susceptible to bias. In one trial from the USA hand washing behaviour was reported to improve; and in the trial from Kenya that provided free soap, hand washing did not increase, but soap use did (data not pooled; three trials, 1845 participants, low quality evidence).Hand washing promotion among communities in LMICs probably prevents around one-quarter of diarrhoea episodes (rate ratio 0.72, 95% CI 0.62 to 0.83; eight trials, 14,726 participants, moderate quality evidence). However, six of these eight trials were from Asian settings, with only single trials from South America and sub-Saharan Africa. In six trials, soap was provided free alongside hand washing education, and the overall average effect size was larger than in the two trials which did not provide soap (soap provided: rate ratio 0.66, 95% CI 0.56 to 0.78; six trials, 11,422 participants; education only: rate ratio: 0.84, 95% CI 0.67 to 1.05; two trials, 3304 participants). There was increased hand washing at major prompts (before eating/cooking, after visiting the toilet or cleaning the baby's bottom), and increased compliance to hand hygiene procedure (behavioural outcome) in the intervention groups than the control in community trials (data not pooled: three trials, 3490 participants, high quality evidence).Hand washing promotion for the one trial conducted in a hospital among high-risk population showed significant reduction in mean episodes of diarrhoea (1.68 fewer) in the intervention group (Mean difference 1.68, 95% CI 1.93 to 1.43; one trial, 148 participants, moderate quality evidence). There was increase in hand washing frequency, seven times per day in the intervention group versus three times in the control in this hospital trial (one trial, 148 participants, moderate quality evidence).We found no trials evaluating or reporting the effects of hand washing promotions on diarrhoea-related deaths, all-cause-under five mortality, or costs. AUTHORS' CONCLUSIONS Hand washing promotion probably reduces diarrhoea episodes in both child day-care centres in high-income countries and among communities living in LMICs by about 30%. However, less is known about how to help people maintain hand washing habits in the longer term.

Process evaluation of a multi-component intervention to reduce infectious diseases and improve hygiene and well-being among school children: the Hi Five study. HEALTH EDUCATION RESEARCH 2015; 30:497-512.

Abstract
The Hi Five study was a three-armed cluster randomized controlled trial designed to reduce infections and improve hygiene and well-being among pupils. Participating schools (n = 43) were randomized into either control (n = 15) or one of two intervention groups (n = 28). The intervention consisted of three components: (i) a curriculum (ii) mandatory daily hand washing before lunch (iii) extra cleaning of school toilets. The aim of this study was to evaluate the implementation and to identify challenges to program implementation. Several data sources were used, including observations of school toilets, semi-structured interviews with school coordinators (n = 4), focus groups with pupils (n = 6) and teachers (n = 5), and questionnaires among pupils (n = 5440), teachers (n = 387) and school coordinators (n = 28). This study indicates that the curriculum was successfully implemented at most schools, and that teachers and pupils reacted positively to this part of the intervention. However, daily hand washing before lunch seems to be difficult to implement. Overall, the implementation process was affected by several factors such as poor sanitary facilities, lack of time and prioritization and objections against the increasing tendency to place the responsibility for child-rearing tasks on schools. This study reveals the strong and weak parts of the Hi Five study and can guide program improvement.

Abstract
BACKGROUND Infectious illnesses such as influenza and diarrhea are leading causes of absenteeism among Danish school children. Interventions in school settings addressing hand hygiene have shown to reduce the number of infectious illnesses. However, most of these studies include small populations and almost none of them are conducted as randomized controlled trials. The overall aim of the Hi Five study was to develop, implement and evaluate a multi-component school-based intervention to improve hand hygiene and well-being and to reduce the prevalence of infections among school children in intervention schools by 20% compared to control schools. This paper describes the development and the evaluation design of Hi Five. METHODS/DESIGN The Hi Five study was designed as a tree-armed cluster-randomized controlled trial. A national random sample of schools (n = 44) was randomized to one of two intervention groups (n = 29) or to a control group with no intervention (n = 15). A total of 8,438 six to fifteen-year-old school children were enrolled in the study. The Hi Five intervention consisted of three components: 1) a curriculum component 2) mandatory daily hand washing before lunch 3) extra cleaning of school toilets during the school day. Baseline data was collected from December 2011 to April 2012. The intervention period was August 2012 to June 2013. The follow-up data was collected from December 2012 to April 2013. DISCUSSION The Hi Five study fills a gap in international research. This large randomized multi-component school-based hand hygiene intervention is the first to include education on healthy and appropriate toilet behavior as part of the curriculum. No previous studies have involved supplementary cleaning at the school toilets as an intervention component. The study will have the added value of providing new knowledge about usability of short message service (SMS, text message) for collecting data on infectious illness and absenteeism in large study populations.

Abstract
Objective.To assess published hand hygiene behavioral interventions that employed a social marketing framework and to recommend improvements to future interventions.Methods.We performed a systematic literature review by searching the PubMed database and the Cumulative Index to Nursing and Allied Health Literature for published articles about hand hygiene behavioral interventions in healthcare facilities, schools, and community settings. Our analysis included articles that describe multifaceted interventions and evaluated them with predefined social marketing benchmark criteria.Results.Of 53 interventions analyzed in this review, 16 (30.2%) employed primary formative audience research, 5 (9.4%) incorporated social or behavioral theories, 27 (50.9%) employed segmentation and targeting of the audience, 44 (83.0%) used components of the “marketing mix,” 3 (5.7%) considered the influence of competing behaviors, 7 (13.2%) cultivated relationships with the target audience, and 15 (28.3%) provided simple behavioral messages. Thirty-five (66.0%) of the interventions demonstrated a significant improvement in performance, but only 21 (39.6%) were considered to have a strong evaluative design. The median duration of the interventions was 8.0 months.Conclusions.From a social marketing perspective, the promotion of hand hygiene could be improved in several ways. The effectiveness of social marketing in hand hygiene promotion should be tested in future interventions.

Abstract
A novel alcohol-based antiseptic and a novel water-based antiseptic lotion, both with a synergistic combination of antimicrobial ingredients containing 0.2% benzethonium chloride, were evaluated using the standard time-kill method against 25 FDA-specified challenge microorganisms. The purpose of the testing was to determine whether a non-alcohol product could have equivalent rapid and broad-spectrum kill to a traditional alcohol sanitizer. Both the alcohol- and water-based products showed rapid and broad-spectrum antimicrobial activity. The average 15-s kill was 99.999% of the challenge organism for the alcohol-based antiseptic and 99.971% for the water-based antiseptic. The alcohol-based product demonstrated 100% of peak efficacy (60s) within the first 15s, whereas the water-based product showed 99.97%. The novel alcohol-based antiseptic reduced concentrations of 100% of organisms by 99.999%, whereas the water-based antiseptic lotion showed the same reduction for 96% of organisms. A novel water-based antiseptic product demonstrated equivalent rapid, broad-spectrum antimicrobial activity to an alcohol-based sanitizer and provided additional benefits of reduced irritation, persistent effect, and greater efficacy against common viruses. The combination of rapid, broad-spectrum immediate kill and persistent efficacy against pathogens may have significant clinical benefit in limiting the spread of disease.

Abstract
BACKGROUND Alcohol-based hand sanitizers (ABHSs) have been widely used in homes, workplaces and schools to prevent the spread of infectious diseases. We report a young child unintentionally ingested ABHS at a school, resulting in intoxication. METHODS The child was a 6-year-old girl who had been brought to the emergency department (ED) for hypothermia, altered mental status (AMS), periods of hypoventilation, hypothermia and vomiting. Computed tomography of her head revealed nothing abnormal in intracranial pathology. Urine drug screening was negative. Alcohol level was 205 mg/dL on admission. Other abnormal values included potassium of 2.8 mEq/L, osmolality of 340 mOsm/kg and no hypoglycemia. Further investigation revealed that the patient had gone frequently to the class restroom for ingestion of unknown quantities of ABHSs during the day. The patient was admitted for one day for intravenous fluid hydration and close observation of her mental status. RESULTS The patient was discharged from the hospital the next day without any complications. CONCLUSION Despite the large safety margin of ABHSs, emergency physicians need to be aware of the potential risk of ingestion of a large amount of such products in children and consider it in the assessment and management of school-age children with acute AMS.

PLoS Med 2014; 11:e1001700.

Abstract
BACKGROUND The potential for transmission of infectious diseases offered by the school environment are likely to be an important contributor to the rates of infectious disease experienced by children. This study aimed to test whether the addition of hand sanitiser in primary school classrooms compared with usual hand hygiene would reduce illness absences in primary school children in New Zealand. METHODS AND FINDINGS This parallel-group cluster randomised trial took place in 68 primary schools, where schools were allocated using restricted randomisation (1:1 ratio) to the intervention or control group. All children (aged 5 to 11 y) in attendance at participating schools received an in-class hand hygiene education session. Schools in the intervention group were provided with alcohol-based hand sanitiser dispensers in classrooms for the winter school terms (27 April to 25 September 2009). Control schools received only the hand hygiene education session. The primary outcome was the number of absence episodes due to any illness among 2,443 follow-up children whose caregivers were telephoned after each absence from school. Secondary outcomes measured among follow-up children were the number of absence episodes due to specific illness (respiratory or gastrointestinal), length of illness and illness absence episodes, and number of episodes where at least one other member of the household became ill subsequently (child or adult). We also examined whether provision of sanitiser was associated with experience of a skin reaction. The number of absences for any reason and the length of the absence episode were measured in all primary school children enrolled at the schools. Children, school administrative staff, and the school liaison research assistants were not blind to group allocation. Outcome assessors of follow-up children were blind to group allocation. Of the 1,301 and 1,142 follow-up children in the hand sanitiser and control groups, respectively, the rate of absence episodes due to illness per 100 child-days was similar (1.21 and 1.16, respectively, incidence rate ratio 1.06, 95% CI 0.94 to 1.18). The provision of an alcohol-based hand sanitiser dispenser in classrooms was not effective in reducing rates of absence episodes due to respiratory or gastrointestinal illness, the length of illness or illness absence episodes, or the rate of subsequent infection for other members of the household in these children. The percentage of children experiencing a skin reaction was similar (10.4% hand sanitiser versus 10.3% control, risk ratio 1.01, 95% CI 0.78 to 1.30). The rate or length of absence episodes for any reason measured for all children also did not differ between groups. Limitations of the study include that the study was conducted during an influenza pandemic, with associated public health messaging about hand hygiene, which may have increased hand hygiene among all children and thereby reduced any additional effectiveness of sanitiser provision. We did not quite achieve the planned sample size of 1,350 follow-up children per group, although we still obtained precise estimates of the intervention effects. Also, it is possible that follow-up children were healthier than non-participating eligible children, with therefore less to gain from improved hand hygiene. However, lack of effectiveness of hand sanitiser provision on the rate of absences among all children suggests that this may not be the explanation. CONCLUSIONS The provision of hand sanitiser in addition to usual hand hygiene in primary schools in New Zealand did not prevent disease of severity sufficient to cause school absence.

Abstract
BACKGROUND School absenteeism because of infections is one of the most important problems facing both public and private primary schools. The aim of the study was to assess the impact of infections on school absenteeism and their reduction with a handwashing program using hand sanitizer. METHODS The study was an 8-month-long, randomized, controlled open study (N = 1,609 children, aged 4-12 years old) at 5 state schools in Almeria (Spain). The experimental group (EG) washed their hands with soap and water, complemented with the use of hand sanitizer, and the control group (CG) followed the usual handwashing procedure. The total number of episodes and days missed as well as those because of upper respiratory infections and gastrointestinal infections were compared in both groups with a Z-test. RESULTS The students were absent 12,386 days in 7,945 episodes. The incidence of total absent episodes and percent of missed days, including those because of upper respiratory infections and gastrointestinal infections, were significantly lower in the EG than the CG (P < .001), and this was maintained through the flu pandemic period. CONCLUSION School absenteeism because of infections in schools is reduced when a hand hygiene program utilizing sanitizing gels is properly carried out, especially during the flu season.

Abstract
BACKGROUND Acute gastroenteritis (AGE) is one of the most common diseases among children and an important cause of school absenteeism. The aim of this study was to assess the effectiveness of a handwashing program using hand sanitizers for the prevention of school absenteeism due to AGE. METHODS A randomized, controlled and open study of a sample of 1341 children between 4 and 12 years of age, attending 5 state schools in Almería (Spain), with an 8-month follow up (academic year). The experimental group (EG) washed their hands with soap and water, complementing this with the use of a hand sanitizer, and the control group (CG) followed the usual handwashing procedure. Absenteeism rates due GI were compared between the 2 groups through the multivariate Poisson regression analysis. Percent days absent in both groups were compared with a Z-test. RESULTS 446 cases of school absenteeism due to AGE were registered. The school children from the EG had a 36% lower risk of absenteeism due to AGE (IRR: 0.64, 95% confidence interval: 0.52-0.78) and a decrease in absenteeism of 0.13 episodes/child/academic year (0.27 of EG vs 0.40 CG/episodes/child/academic year, P < 0.001). Pupils missed 725 school days due to AGE and absent days was significantly lower in the EG (EG: 0.31%, 95% confidence interval: 0.28-0.35 vs. CG: 0.44%, 95% confidence interval: 0.40-0.48, P < 0.001). CONCLUSIONS The use of hand sanitizer as a complement to handwashing with soap is an efficient measure to reduce absent days and the number of school absenteeism cases due to AGE.

Abstract
PURPOSE This review was done to explore the impact of water treatment, hygiene, and sanitary interventions on improving child health outcomes such as absenteeism, infections, knowledge, attitudes, and practices and adoption of point-of-use water treatment. METHODS A literature search was conducted using the databases PubMed and Google scholar for studies published between 2009 and 2012 and focusing on the effects of access to safe water, hand washing facilities, and hygiene education among school-age children. Studies included were those that documented the provision of water and sanitation in schools for children less than 18 years of age, interventions which assessed WASH practices, and English-language, full-text peer reviewed papers. RESULTS Fifteen studies were included in the final analysis. 73% (n = 11) of the studies were conducted in developing countries and were rural based (53%, n = 8). The child's age, gender, grade level, socioeconomic index, access to hygiene and sanitary facilities, and prior knowledge of hygiene practices were significantly associated with the outcomes. Nutrition practices which are key factors associated with the outcomes were rarely assessed. CONCLUSION Further research is required to assess the long-term impact of such interventions in different settings.

Abstract
The workplace is an important location to access community members, and employers have a direct interest in employee well-being. A survey administered to a random sample of employees at a Midwestern US university tested the ability of a model informed by the theory of planned behavior to predict hand hygiene practices and beliefs using structural equation modeling. Questions demonstrated acceptable validity and reliability. Constructs predicted self-reported hand hygiene behaviors, and hand hygiene behaviors reduced the odds of reporting sickness from respiratory tract and gastrointestinal infections. The findings support multi-modal hand hygiene improvement interventions.

Abstract
OBJECTIVE To investigate the predictors of use of anti-amoebiasis protective measures (AAPMs) among Taiwan immigrants returning to their country of origin, using the Health Belief Model (HBM) to guide the investigation. DESIGN Cross-sectional study. METHODS Between March and May 2011, all permanent immigrants originating from amoebiasis-endemic countries who received services at the immigrant service centres in Taipei or Tainan and who reported that they had returned to their country of origin within the past five years were enrolled in the study. A structured questionnaire containing questions on sociodemographic characteristics and items related to the constructs of the HBM was used as the data collection instrument. RESULTS Complete information was collected from 384 immigrants, with a response rate of 80% (384/480). The mean age of the subjects was 38.4 years (standard deviation 10.6 years). The majority (70%) of participants did not receive travel information through a pretravel consultation, and more than 17% reported that they did not use measures to prevent amoebiasis. Multiple regression analyses revealed that Chinese proficiency, pretravel consultation and lower barriers to using protective measures were significantly associated with the use of AAPMs during return trips to country of origin (R(2) = 0.45; F = 77.5; P < 0.001). CONCLUSION The HBM significantly predicted the use of AAPMs in this study. A high proportion of immigrants did not use appropriate AAPMs when they returned to their country of origin. Educational approaches should be targeted at immigrants originating from amoebiasis-endemic regions who return to their country of origin.

Abstract
Handwashing is difficult in settings with limited resources and water access. In primary schools within urban Kibera, Kenya, we investigated the impact of providing waterless hand sanitizer on student hand hygiene behavior. Two schools received a waterless hand sanitizer intervention, two schools received a handwashing with soap intervention, and two schools received no intervention. Hand cleaning behavior after toilet use was monitored for 2 months using structured observation. Hand cleaning after toileting was 82% at sanitizer schools (N = 2,507 toileting events), 38% at soap schools (N = 3,429), and 37% at control schools (N = 2,797). Students at sanitizer schools were 23% less likely to have observed rhinorrhea than control students (P = 0.02); reductions in student-reported gastrointestinal and respiratory illness symptoms were not statistically significant. Providing waterless hand sanitizer markedly increased student hand cleaning after toilet use, whereas the soap intervention did not. Waterless hand sanitizer may be a promising option to improve student hand cleansing behavior, particularly in schools with limited water access.

Abstract
Home and everyday life hygiene is a key part of the public health strategy to reduce infectious disease, but an effective code of practice is required. This short review summarizes the basic scientific principles of a risk-based approach to home hygiene where hygiene procedures are applied at critical points at appropriate times. It suggests that, although detergent-based cleaning can be used to break the chain of infection, in some cases an antimicrobial agent is required.

Abstract
Community hand hygiene interventions have reduced the spread of infectious disease in elementary schools, daycare centers, and private homes. Despite this success, and the potential for reducing workplace absenteeism and presenteeism, few peer-reviewed hand hygiene intervention studies among workers have been published. This research used the Theory of Planned Behavior (TPB) to guide the development of a model to understand and predict motivations for performing hand hygiene, and to examine related illness, absenteeism, and presenteeism among employees from 39 bank branches in Ohio. Although the TPB has been used extensively to elucidate hand hygiene practices among employees in the health care and food industries, little is known about the ability of the TPB to predict hand hygiene practices among workers in public settings. These survey findings indicate a need for hand hygiene improvement, and support the use of attitudinal beliefs and social norms to guide multimodal approaches for workplace hand hygiene interventions.

Abstract
Introduction Children are important transmitters of influenza in the community and a number of non-pharmaceutical interventions (NPIs), including hand washing and use of hand sanitizer, have been recommended to mitigate the transmission of influenza, but limited information is available regarding schools' ability to implement these NPIs during an influenza outbreak. We evaluated implementation of NPIs during fall 2009 in response to H1N1 pandemic influenza (pH1N1) by New York City (NYC) public schools. Methods From January 25 through February 9, 2010, an online survey was sent to all the 1,632 NYC public schools and principals were asked to participate in the survey or to designate a school nurse or other school official with knowledge of school policies and characteristics to do so. Results Of 1,633 schools, 376(23%) accessed and completed the survey. Nearly all respondents (99%) implemented at least two NPIs. Schools that had a Flu Response Team (FRT) as a part of school emergency preparedness plan were more likely to implement the NPI guidelines recommended by NYC public health officials than schools that did not have a FRT. Designation of a room for isolating ill students, for example, was more common in schools with a FRT (72%) than those without (53%) (p<0.001). Conclusions Implementing an NPI program in a large school system to mitigate the effects of an influenza outbreak is feasible, but there is potential need for additional resources in some schools to increase capacity and adherence to all recommendations. Public health influenza-preparedness plans should include school preparedness planning and FRTs.

Abstract
A multiple baseline across groups design was used to investigate the effects of a treatment package on hand washing before lunch by five students with disabilities who attended a young adult educational program. To evaluate hand washing, a lotion called Glo Germ was applied to participants' hands. Glo Germ is visible under a black light, which allowed the quality of hand washing to be assessed by comparing the amount visible before and after hand washing using a 3-point scale. Following a baseline period in which hand washing was assessed, participants were exposed to a hand washing training procedure, which improved one participant's hand washing. Next, a lottery system was imposed in which the number of lottery tickets earned each day depended on the quality of hand washing, specifically, on the rating assigned (0, 1, or 2). This condition was associated with improved hand washing by the other four participants. Finally, a condition adding feedback to the lottery system resulted in further improvements in the quality of hand washing for all participants. Follow up data indicated modest maintenance of hand washing after lunch. These results suggest that treatment packages similar to that used in the present study merit further investigation and that Glo Germ is of value in ascertaining the quality of hand washing.

Abstract
BACKGROUND Viral upper respiratory tract infections have been implicated as a major cause of asthma exacerbations among school-aged children. Regular hand washing is the most effective method to prevent the spread of viral respiratory tract infections, but effective hand-washing practices are difficult to establish in schools. OBJECTIVES This randomized controlled trial evaluated whether a standardized regimen of hand washing plus alcohol-based hand sanitizer could reduce asthma exacerbations more than schools' usual hand hygiene practices. METHODS This was a 2-year, community-based, randomized controlled crossover trial. Schools were randomized to usual care and then intervention (sequence 1) or intervention and then usual care (sequence 2). Intervention schools were provided with alcohol-based hand sanitizer, hand soap, and hand hygiene education. The primary outcome was the proportion of students experiencing an asthma exacerbation each month. Generalized estimating equations were used to model the difference in the marginal rate of exacerbations between sequences while controlling for individual demographic factors and the correlation within each student and between students within each school. RESULTS Five hundred twenty-seven students with asthma were enrolled among 31 schools. The hand hygiene intervention did not reduce the number of asthma exacerbations compared with the schools' usual hand hygiene practices (P = .132). There was a strong temporal trend because both sequences experienced fewer exacerbations during year 2 compared with year 1 (P < .001). CONCLUSIONS Although the intervention was not found to be effective, the results were confounded by the H1N1 influenza pandemic that resulted in substantially increased hand hygiene behaviors and resources in usual-care schools. Therefore these results should be viewed cautiously.

Abstract
OBJECTIVES The purpose of this study was to determine to what extent school-aged children can learn hygiene-based nonpharmaceutical interventions (NPIs) and persist in these behavioral changes over the duration of an influenza season. If this can be done successfully, it may be a preferable pandemic mitigation strategy to much more disruptive strategies such as whole-scale school closure. METHODS The Pittsburgh Influenza Prevention Project (PIPP) is a prospective, controlled, randomized trial of the effectiveness of a suite of hygiene-based NPIs in controlling influenza and related illnesses in elementary schools in the City of Pittsburgh. During the 2007-08 school year, the project measured adoption of NPIs by students in five elementary schools through surveys of home-room teachers before, during, and after influenza season. RESULTS Results showed highly statistically significant improvement in students' daily practice of nearly all of the NPIs, including hand washing and sanitizer use and covering coughs and sneezes. CONCLUSIONS The study provides evidence that children can learn, implement, and persist in the behaviors of a multilayered suite of NPIs over a typical flu season. These results will be useful to public health policy makers and practitioners considering methods of infectious disease prevention in school-based settings.

Abstract
Background Illness-related absences have been shown to lead to negative educational and economic outcomes. Both hand washing and hand sanitizer interventions have been shown to be effective in reducing illness-related absences. However, while the importance of hand hygiene in schools is clear, the role of instruction in use is less obvious. The purpose of this study was to compare absenteeism rates among elementary students given access to hand hygiene facilities versus students given both access and short repetitive instruction in use, particularly during influenza season when illness-related absences are at a peak. Methods A hand hygiene intervention was implemented from October to May during the 2009/2010 academic year, including peak flu season, in two Chicago Public Elementary Schools among students grades pre-kindergarten to eighth grade (ages 4–14). Classrooms were systematically assigned to an intervention or control group by grade (cluster design). Hand hygiene facilities (sanitizer and soap) were made available to all students. Students in the intervention group also received short repetitive instruction in hand hygiene every 2 months. Only absences as a result of respiratory or gastrointestinal illness were used to establish illness-related absenteeism rates. Percent absent days were calculated and bivariate analyses were performed to compare percent absent days among students given access to hand hygiene facilities versus students given both access and instruction. Prior to the intervention, teachers’ perceptions of students’ hand hygiene were also evaluated. Teacher perceptions were analysed to describe attitudes and beliefs. Results Data were collected and analysed for 773 students reporting 1,886 absences during the study period (1.73% of total school days). Both the percent total absent days and percent illness-related absent days were significantly lower in the group receiving short instruction during flu season (P = 0.002, P < 0.001, respectively). This difference peaked during the influenza season (when intervention began) and declined in the following months. Teachers (n = 23) agreed that hand hygiene is not performed properly among students and reported time constraints as a barrier to frequent hand washing. Conclusions Adding hand hygiene instruction to existing hand hygiene practices improved attendance at public elementary schools during the flu season. Standardized and brief repetitive instruction in hand hygiene holds potential to significantly reduce absenteeism.

Abstract
BACKGROUND It has been shown that nontoxic concentrations of ethanol are absorbed after hand hygiene using ethanol-based hand rubs. This study investigated whether absorption of propan-1-ol and propan-2-ol from commercially available hand rubs results in measurable concentrations after use. METHODS The pulmonary and dermal absorption of propanol during hand rubs was investigated. Rubs contained 70% (w/w) propan-1-ol, 63.14% (w/w) propan-2-ol, or 45% (w/w) propan-2-ol in combination with 30% (w/w) propan-1-ol. RESULTS Peak median blood levels were 9.15 mg/L for propan-1-ol and 5.3 mg/L for propan-2-ol after hygienic hand rubs and 18.0 mg/L and 10.0 mg/L, respectively, after surgical hand rubs. Under actual surgical conditions, the highest median blood levels were 4.08 mg/L for propan-1-ol and 2.56 mg/L for propan-2-ol. The same procedure performed with prevention of pulmonary exposure through the use of a gas-tight mask resulted in peak median blood levels of 1.16 mg/L of propan-1-ol and 1.74 mg/L of propan-2-ol. CONCLUSION Only minimal amounts of propanols are absorbed through the use of hand rubs. Based on our experimental data, the risk of chronic systemic toxic effects caused by hand rubs is likely negligible. However, our study did not evaluate the consequences of long-term daily and frequent use of hygienic hand rubs.

Abstract
OBJECTIVES There has been increased attention to access to water, sanitation and hygiene (WASH) at schools in developing countries, but a dearth of empirical studies on the impact. We conducted a cluster-randomized trial of school-based WASH on pupil absence in Nyanza Province, Kenya, from 2007 to 2008. METHODS Public primary schools nested in three geographical strata were randomly assigned and allocated to one of three study arms [water treatment and hygiene promotion (WT & HP), additional sanitation improvement, or control] to assess the effects on pupil absence at 2-year follow-up. RESULTS We found no overall effect of the intervention on absence. However, among schools in two of the geographical areas not affected by post-election violence, those that received WT and HP showed a 58% reduction in the odds of absence for girls (OR 0.42, CI 0.21-0.85). In the same strata, sanitation improvement in combination with WT and HP resulted in a comparable drop in absence, although results were marginally significant (OR 0.47, 0.21-1.05). Boys were not impacted by the intervention. CONCLUSION School WASH improvements can improve school attendance for girls, and mechanisms for gendered impacts should be explored. Incomplete intervention compliance highlights the challenges of achieving consistent results across all settings.

Abstract
Background Asthma exacerbations are seasonal with the greatest risk in elementary-age
students occurring shortly after returning to school following summer break. Recent
research suggests that this seasonality in children is primarily related to viral
respiratory tract infections. Regular hand washing is the most effective method to
prevent the spread of viral respiratory infections; unfortunately, achieving hand
washing recommendations in schools is difficult. Therefore, we designed a study to
evaluate the effect of hand sanitizer use in elementary schools on exacerbations
among children with asthma. Purpose To describe the process of redesigning the trial in response to changes in
the safety profile of the hand sanitizer as well as changes in hand hygiene practice
in the schools. Methods The original trial was a randomized, longitudinal, subject-blinded,
placebo-controlled, community-based crossover trial. The primary aim was to evaluate
the incremental effectiveness of hand sanitizer use in addition to usual hand hygiene
practices to decrease asthma exacerbations in elementary-age children. Three events
occurred that required major modifications to the original study protocol: (1) safety
concerns arose regarding the hand sanitizer’s active ingredient; (2) no substitute
placebo hand sanitizer was available; and (3) community preferences changed regarding
hand hygiene practices in the schools. Results The revised protocol is a randomized, longitudinal, community-based crossover
trial. The primary aim is to evaluate the incremental effectiveness of a two-step
hand hygiene process (hand hygiene education plus institutionally provided
alcohol-based hand sanitizer) versus usual care to decrease asthma exacerbations.
Enrollment was completed in May 2009 with 527 students from 30 schools. The
intervention began in August 2009 and will continue through May 2011. Study results
should be available at the end of 2011. Limitations The changed design does not allow us to directly measure the effectiveness of
hand sanitizer use as a supplement to traditional hand washing practices. Conclusions The need to balance a rigorous study design with one that is acceptable to
the community requires investigators to be actively involved with community
collaborators and able to adapt study protocols to fit changing community
practices.

Abstract
BACKGROUND Laboratory-based evidence is lacking regarding the efficacy of nonpharmaceutical interventions (NPIs) such as alcohol-based hand sanitizer and respiratory hygiene to reduce the spread of influenza. METHODS The Pittsburgh Influenza Prevention Project was a cluster-randomized trial conducted in 10 elementary schools in Pittsburgh, PA, during the 2007 to 2008 influenza season. Children in 5 intervention schools received training in hand and respiratory hygiene, and were provided and encouraged to use hand sanitizer regularly. Children in 5 schools acted as controls. Children with influenza-like illness were tested for influenza A and B by reverse-transcriptase polymerase chain reaction. RESULTS A total of 3360 children participated in this study. Using reverse-transcriptase polymerase chain reaction, 54 cases of influenza A and 50 cases of influenza B were detected. We found no significant effect of the intervention on the primary study outcome of all laboratory-confirmed influenza cases (incidence rate ratio [IRR]: 0.81; 95% confidence interval [CI]: 0.54, 1.23). However, we did find statistically significant differences in protocol-specified ancillary outcomes. Children in intervention schools had significantly fewer laboratory-confirmed influenza A infections than children in control schools, with an adjusted IRR of 0.48 (95% CI: 0.26, 0.87). Total absent episodes were also significantly lower among the intervention group than among the control group; adjusted IRR 0.74 (95% CI: 0.56, 0.97). CONCLUSIONS NPIs (respiratory hygiene education and the regular use of hand sanitizer) did not reduce total laboratory-confirmed influenza. However, the interventions did reduce school total absence episodes by 26% and laboratory-confirmed influenza A infections by 52%. Our results suggest that NPIs can be an important adjunct to influenza vaccination programs to reduce the number of influenza A infections among children.
