Pilot of an Elementary School Cough Etiquette Intervention: Acceptability, Feasibility, and Potential for Sustainability

Non-pharmaceutical interventions to reduce influenza transmission in households: a systematic review and meta-analysis

BACKGROUND

Influenza pandemic plans often recommend non-pharmaceutical interventions (NPIs) in household settings, including hand hygiene and face masks. We reviewed the evidence supporting the recommendations of these measures to prevent the spread of influenza in households.

METHODS

We performed systematic reviews between 26 May and 30 August 2022 in Medline, PubMed, EMBASE, and CENTRAL to identify evidence for the effectiveness of selected measures recommended by representative national influenza pandemic plans. We prioritized evidence from randomized controlled trials conducted during influenza pandemics and seasonal influenza epidemics. Fixed-effects models were used to estimate the overall effects. Systematic reviews were registered in the OSF registry (https://osf.io/8kyth).

RESULTS

We selected 9 NPIs for evidence review. We identified 9 randomized-controlled trials related to hand hygiene and face masks in household settings. 2 studies reported that measures could delay the introduction of influenza virus infections into households. However, we did not identify evidence from randomized controlled trials that indicated a substantial effect of hand hygiene and face masks in preventing the spread of influenza within households.

CONCLUSION

Limited evidence indicated that within-household measures may likely be effective only when implemented before or as soon as possible after symptom onset in an infected case. Improving the evidence base for NPIs in households and elsewhere is a continuing priority.

Kukaa Salama (Staying Safe): a pre-post trial of an interactive informational mobile health intervention for increasing COVID-19 prevention practices with urban refugee youth in Uganda

BACKGROUND

Tailored coronavirus disease 2019 (COVID-19) prevention strategies are needed for urban refugee youth in resource-constrained contexts. We developed an 8-wk interactive informational mobile health intervention focused on COVID-19 prevention practices informed by the Risk, Attitude, Norms, Ability, Self-regulation-or RANAS-approach.

METHODS

We conducted a pre-post trial with a community-recruited sample of refugee youth aged 16-24 y in Kampala, Uganda. Data were collected before (T1) and immediately following (T2) the intervention, and at the 16-wk follow up (T3), to examine changes in primary (COVID-19 prevention self-efficacy) and secondary outcomes (COVID-19 risk awareness, attitudes, norms and self-regulation practices; depression; sexual and reproductive health [SRH] access; food/water security; COVID-19 vaccine acceptability).

RESULTS

Participants (n=346; mean age: 21.2 [SD 2.6] y; cisgender women: 50.3%; cisgender men: 48.0%; transgender persons: 1.7%) were largely retained (T2: n=316, 91.3%; T3: n=302, 87.3%). In adjusted analyses, COVID-19 prevention self-efficacy, risk awareness, attitudes and vaccine acceptance increased significantly from T1 to T2, but were not sustained at T3. Between T1 and T3, COVID-19 norms and self-regulation significantly increased, while community violence, water insecurity and community SRH access decreased.

CONCLUSIONS

Digital approaches for behaviour change hold promise with urban refugee youth but may need booster messaging and complementary programming for sustained effects.

Kukaa Salama (Staying Safe): study protocol for a pre/post-trial of an interactive mHealth intervention for increasing COVID-19 prevention practices with urban refugee youth in Kampala, Uganda

INTRODUCTION

With over 82.4 million forcibly displaced persons worldwide, there remains an urgent need to better describe culturally, contextually and age-tailored strategies for preventing COVID-19 in humanitarian contexts. Knowledge gaps are particularly pronounced for urban refugees who experience poverty, overcrowded living conditions and poor sanitation access that constrain the ability to practise COVID-19 mitigation strategies such as physical distancing and frequent hand washing. With over 1.4 million refugees, Uganda is sub-Saharan Africa's largest refugee hosting nation. More than 90 000 of Uganda's refugees live in Kampala, most in informal settlements, and 27% are aged 15-24 years old. There is an urgent need for tailored COVID-19 responses with urban refugee adolescents and youth. This study aims to evaluate the effectiveness of an 8-week interactive informational mobile health intervention on COVID-19 prevention practices among refugee and displaced youth aged 16-24 years in Kampala, Uganda.

METHODS AND ANALYSIS

We will conduct a pre-test/post-test study nested within a larger cluster randomised trial. Approximately 385 youth participants will be enrolled and followed for 6 months. Data will be collected at three time points: before the intervention (time 1); immediately after the intervention (time 2) and at 16-week follow-up (time 3). The primary outcome (self-efficacy to practise COVID-19 prevention measures) and secondary outcomes (COVID-19 risk awareness, attitudes, norms and self-regulation practices; depression; sexual and reproductive health practices; food and water security; COVID-19 vaccine acceptability) will be evaluated using descriptive statistics and regression analyses.

ETHICS AND DISSEMINATION

This study has been approved by the University of Toronto Research Ethics Board, the Mildmay Uganda Research Ethics Committee, and the Uganda National Council for Science & Technology. The results will be published in peer-reviewed journals, and findings communicated through reports and conference presentations.

Decrease of respiratory diseases in one social children welfare institute in Shanxi Province during COVID-19

Background

To assess the impact of disinfection measures on the incidence of common diseases in children welfare institute during the epidemic of Corona Virus Disease 2019 (COVID-19), and provide a basis for the daily disinfection management of children welfare institute.

Methods

This study surveyed and analyzed common diseases among children under the age of 14 in one social children welfare institute in Shanxi Province from January to May in 2018–2020 by the year-on-year method.

Results

The prevalence rate of respiratory diseases in 2020 was a significantly negative growth compared with 2018 and 2019. There was no obvious pattern of changes in digestive diseases group.

Conclusion

In view of the above anti-epidemic measures, it indicates that the children gathering institutions should strengthen effective personal protection and public health management to reduce infectious disease among children.

Piloting an acceptable and feasible menstrual hygiene products disposal system in urban and rural schools in Bangladesh

BACKGROUND

Access to washroom facilities and a place to dispose of menstrual waste are prerequisites for optimal menstrual hygiene management in schools. Like other low- and middle-income countries, Bangladeshi schools lack facilities for girls to change and dispose of their menstrual absorbents. We explored existing systems for disposing of menstrual absorbent wastes in urban and rural schools of Bangladesh and assessed the feasibility and acceptability of alternative disposal options.

METHODS

We explored how girls dispose of their menstrual products, identified girls' preferences and choices for a disposal system and piloted four disposal options in four different schools. We then implemented one preferred option in four additional schools. We explored girls', teachers', and janitors' perspectives and evaluated the acceptability, feasibility, and potential for sustainability of the piloted disposal system.

RESULTS

Barriers to optimal menstrual hygiene management included lack of functional toilets and private locations for changing menstrual products, and limited options for disposal. Girls, teachers, and janitors preferred and ranked the chute disposal system as their first choice, because it has large capacity (765 L), is relatively durable, requires less maintenance, and will take longer time to fill. During implementation of the chute disposal system in four schools, girls, teachers, and janitors reported positive changes in toilet cleanliness and menstrual products disposal resulting from the intervention.

CONCLUSIONS

The chute disposal system for menstrual products is a durable option that does not require frequent emptying or regular maintenance, and is accepted by schoolgirls and janitors alike, and can improve conditions for menstrual hygiene management in schools. However, regular supervision, motivation of girls to correctly dispose of their products, and a long-term maintenance and management plan for the system are necessary.

Effectiveness of a Behavior Change Intervention with Hand Sanitizer Use and Respiratory Hygiene in Reducing Laboratory-Confirmed Influenza among Schoolchildren in Bangladesh: A Cluster Randomized Controlled Trial

Schoolchildren are commonly linked to influenza transmission. Handwashing with soap has been shown to decrease infections; however, improving handwashing practices using soap and water is difficult in low-resource settings. In these settings, alternative hygiene options, such as hand sanitizer, could improve handwashing promotion to reduce influenza virus infections. We conducted a cluster randomized control trial in 24 primary schools in Dhaka to assess the effectiveness of hand sanitizer and a respiratory hygiene education intervention in reducing influenza-like illness (ILI) and laboratory-confirmed influenza during June-September 2015. Twelve schools were randomly selected to receive hand sanitizer and respiratory hygiene education, and 12 schools received no intervention. Field staff actively followed children daily to monitor for new ILI episodes (cough with fever) through school visits and by phone if a child was absent. When an illness episode was identified, medical technologists collected nasal swabs to test for influenza viruses. During the 10-week follow-up period, the incidence of ILI per 1,000 student-weeks was 22 in the intervention group versus 27 in the control group (P-value = 0.4). The incidence of laboratory-confirmed influenza was 53% lower in the intervention schools (3/1,000 person-weeks) than in the control schools (6/1,000 person-weeks) (P-value = 0.01). Hand sanitizer and respiratory hygiene education can help to reduce the risk of influenza virus transmission in schools.

Piloting a Shared Source Water Treatment Intervention among Elementary Schools in Bangladesh

Hundreds of thousands of children continue to die each year from diarrhea. We piloted a low-cost liquid chlorine point-of-use (POU) water treatment among elementary school children in Bangladesh. We began the 1-month intervention in four schools (two urban and two rural) by introducing POU drinking water hardware and behavior change communication. We trained teachers to deliver sessions encouraging students to drink chlorinated water from their own small plastic bottles to avoid disease transmission. We used cue cards and flip charts as visual aids. We evaluated the acceptability, feasibility, and potential for sustainability after 1 month and after 14 months of the intervention. During 1-month follow-up, among 141 drinking events observed, 141 students (100%) drank chlorinated water. In 93 or 66% of events, students used their own bottles, and in 43 (30%) of the events, they used common cups or hands washed before drinking. During the 14-month follow-up, we observed 732 drinking events. In 653 of 732 events (89%), students drank chlorinated water; in 78 events (11%), they consumed water from untreated drinking water sources. Among those who consumed chlorinated water, 20% (131/653) used their own bottles to drink water, 72% (467/653) used common cups, and 8% (55/653) used both hands to drink water. Most stated that they drank chlorinated water because it is safe, it has health benefits, and treatment reduces germs. Introduction of specific hardware, weekly hygiene sessions, and education materials enabled schools to treat water at POU and students to consume treated water.
