Abstract
Background: Vaccination against rotavirus was offered in Stockholm to children born on 1 March 2014 and onwards with 85% coverage after two years. We investigated changes in nosocomial diarrhoea 2010-2018 in children admitted to Astrid Lindgren Children's Hospital, Stockholm, Sweden. Methods: We retrospectively identified cases from diagnostic and virology department registers. Complications and chronic medical conditions were retrieved from the case records. Children <18 years of age who developed diarrhoea ≥48 h after admission for another diagnosis and had a faecal sample submitted to the virology department were included. Results: There were 474 episodes of nosocomial diarrhoea. Of these, 401 (85%) occurred in children with chronic medical conditions. In children <5 years the rates of nosocomial rotavirus gastroenteritis, with 95% confidence intervals, significantly decreased from 0.34 (0.25-0.45) per 100 admissions prevaccination to 0.09 (0.04-0.17) postvaccination and from 0,66 (0.48-0.88) to 0.16 (0.07-0.30) cases per 1000 hospital days. Postvaccination norovirus became the most frequent pathogen. Virus-positive cases were more common in young children and in winter months. Conclusions: Before the initiation of rotavirus vaccination, norovirus and rotavirus were equally common causes of nosocomial diarrhoea. Postvaccination, rotavirus was reduced by approximately 75% while the frequency of other viruses did not change.

Abstract
In infants with immunodeficiency, rotavirus (RV) vaccines can be continuously excreted in stool. We analysed nosocomial infection with RV vaccine strain in immunodeficient paediatric patients. RV1 RNAs were detected in stool and serum samples from case A, who was vaccinated with RV1, and case B, who was not. PAGE analysis of serial stool samples of case A revealed several rearrangements of the RV genome. In case B, the only band pattern detected was the same as a rearrangement detected in case A at the same time. In summary, RV vaccination of infants with immunodeficiency poses a risk of nosocomial infections.

Rotavirus disease and health care utilisation among children under 5 years of age in highly developed countries: A systematic review and meta-analysis. Vaccine 2021; 39:2917-2928. [PMID: 33934916 DOI: 10.1016/j.vaccine.2021.04.039] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2020] [Revised: 04/16/2021] [Accepted: 04/17/2021] [Indexed: 10/21/2022]
Abstract
BACKGROUND Rotavirus (RV) infection is the leading cause of diarrhoea-associated morbidity and mortality globally among children under 5 years of age. RV vaccination is available, but has not been implemented in many national immunisation plans, especially in highly developed countries. This systematic review aimed to estimate the prevalence and incidence of health care use for RV gastroenteritis (RVGE) among children aged under 5 years in highly developed countries without routine RV vaccination. METHODS We searched MEDLINE and Embase databases from January 1st 2000 to December 17th 2018 for publications reporting on incidence or prevalence of RVGE-related health care use in children below 5 years of age: primary care and emergency department (ED) visits, hospitalisations, nosocomial infections and deaths. We included only studies with laboratory-confirmed RV infection, undertaken in highly developed countries with no RV routine vaccination plans. We used random effects meta-analysis to generate summary estimates with 95% confidence intervals (CI) and prediction intervals. RESULTS We screened 4033 abstracts and included 74 studies from 21 countries. Average incidence rates of RVGE per 100 000 person-years were: 2484 (95% CI 697-5366) primary care visits, 1890 (1597-2207) ED visits, 500 (422-584) hospitalisations, 34 (20-51) nosocomial infections and 0.04 (0.02-0.07) deaths. Average proportions of cases of acute gastroenteritis caused by RV were: 21% (95% CI 16-26%) for primary care visits; 32% (25-38%) for ED visits; 41% (36-47%) for hospitalisations, 29% (25-34%) for nosocomial infections and 12% (8-18%) for deaths. Results varied widely between and within countries, and heterogeneity was high (I2 > 90%) in most models. CONCLUSION RV in children under 5 years causes many healthcare visits and hospitalisations, with low mortality, in highly developed countries without routine RV vaccination. The health care use estimates for RVGE obtained by this study can be used to model RV vaccine cost-effectiveness in highly developed countries.

Introduction of rotavirus vaccination in a Swedish region: assessing parental decision-making, obtained vaccination coverage and resulting hospital admissions. Acta Paediatr 2019; 108:1329-1337. [PMID: 30507015 DOI: 10.1111/apa.14674] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/14/2018] [Revised: 11/26/2018] [Accepted: 11/27/2018] [Indexed: 11/28/2022]
Abstract
AIM This study evaluated the introduction of rotavirus vaccination in Jönköping County, Sweden, starting in 2014. This project explored the parental factors that influenced the decision to vaccinate and studied the obtained vaccination coverage and its potential influence on hospital admissions due to acute gastroenteritis. METHODS This was a descriptive, cross-sectional study based on a study-specific questionnaire (n = 356) and regional statistical data on vaccination coverage and hospital admissions in Jönköping County, Sweden. RESULTS Central aspects when deciding on vaccination were vaccine efficacy and safety, that the vaccine was offered to all children, and recommended by healthcare professionals. One in five parents expressed uncertainty about whether they had sufficient information to make a decision. However, the rotavirus vaccination coverage was elevated from 76.1% to 81.0% and the hospital admissions due to acute gastroenteritis decreased by approximately 60%. CONCLUSION The results highlight the necessity for Child Health Services to have solid knowledge regarding vaccinations, to understand individual parental issues and to support uncertain parents. The high vaccination coverage achieved is an indication of the trust in healthcare professionals and is considered to be a major contributing factor to the substantial reduction of hospital admissions due to acute gastroenteritis.

Abstract
The transmission of infectious agents within healthcare settings is a priority public health problem. Although the main burden of healthcare-associated infections is commonly caused by Gram-negative bacteria and fungi, vaccine-preventable diseases represent an additional infectious risk for patients attending healthcare facilities. Hepatitis B, rotavirus gastroenteritis, influenza, measles, pertussis and pneumococcal and meningococcal invasive bacterial infections still represent a threat, notwithstanding the presence of universal vaccination programs. For this reason, healthcare worker immunization is an important strategy to limit the risk of vaccine-preventable diseases in such a fragile population.

Abstract
Rotavirus (RV) is the leading cause of severe gastroenteritis in young children. However, because the incorporation of live-attenuated RV vaccines as part routine childhood immunization schedules, the rates of hospitalization from RV infections have decreased significantly across the globe. While RV vaccine safety and effectiveness have been well documented in the general population, there is controversy surrounding its use in preterm and immunocompromised infants. In this article, we review current research and consensus statements on the safety of the RV vaccine, the immunogenicity of the response and the potential for transmission and shedding of the virus postvaccination in both preterm infants and immunocompromised infants. RV vaccines are well tolerated in hospitalized preterm infants with no significant increase in nosocomial infections, gastrointestinal complications or feeding difficulties. In select immunocompromised infants (such as HIV-infected or HIV-exposed infants), RV vaccine administration did not increase the rate of adverse events. However, multiple case reports noted increased rates of adverse events in infants with severe combined immunodeficiency. The risk of viral shedding and transmission between vaccinated neonates and household contacts remain low and does not outweigh the benefit of vaccination.

Abstract
BACKGROUND During one week in September, one index case, followed by two cases of rotavirus gastroenteritis infection, was identified in a neonate intermediate care unit of a tertiary teaching children's hospital. An outbreak investigation was launched to clarify the possible infection source and to stop the spread of infection. METHODS Cohort care and environmental disinfection were immediately implemented. We screened rotavirus in all the unit neonates' stool samples as well as environmental swab samples. The precautionary measures with regard to hand hygiene and contact isolation taken by healthcare providers and family members were re-examined. RESULTS The fourth case was identified 5 days after commencement of the outbreak investigation. There were total 39 contacts, including 6 neonates, 8 family members, and 25 healthcare providers. Nineteen stool samples collected from other neonates in the units revealed one positive case (the fourth case). However, one sample taken from the computer keyboard and mouse in the ward was also positive. The observation of hygiene precautions and the use of isolation gowns by healthcare workers were found to be inadequate. Following the intensification of infection control measures, no further cases of infection were reported. CONCLUSIONS Hand hygiene and an intensive isolation strategy remained the most critical precautions for preventing an outbreak of healthcare-associated viral gastroenteritis in the neonate care unit.

Abstract
Enteric viruses are the most common cause of acute gastroenteritis (AGE) in young children and a significant public health problem globally. Hospital admissions of children under 5 years of age with diarrhea are primarily associated with group A rotavirus (RVA) infection. In this retrospective study, the population structure of viruses linked to AGE etiology in young children hospitalized with AGE in Moscow was evaluated, and molecular characterization of RVA strains was performed. Fecal specimens were collected from children under 5 years old hospitalized with AGE between 2009 and 2014 in Moscow, Russia. Multiplex real-time reverse transcription PCR was used to detect enteric viruses and for G/[P]-genotyping of isolated RVAs. Sequencing of RVA VP7 and VP4 cDNA fragments was used to validate the data obtained by PCR-genotyping. The main causes for hospitalization of children with AGE were RVA (40.1%), followed by noroviruses (11.4%), while adenoviruses, astroviruses, sapoviruses, enteroviruses, and orthoreoviruses were detected in 4.7%, 1.9%, 1.4%, 1.2%, and 0.2% of samples tested, respectively. Nosocomial infections, predominantly associated with RVAs and noroviruses, were detected in 24.8% of cases and occurred significantly more frequently in younger infants. The predominant RVA genotype was G4P[8], detected in 38.7% of RVA-positive cases, whereas genotypes G1P[8], G9P[8], G3P[8], and G2P[4] were found in 11.8%, 6.6%, 4.2%, and 3.3% of cases, respectively. Together, the presence of circulating RVA strains with rare VP7 and VP4 gene variants (G6 and P[9]) highlights the need to conduct continuous epidemiological monitoring of RVA infection.

Abstract
STUDY OBJECTIVE Most studies of children with isolated skull fractures have been relatively small, and rare adverse outcomes may have been missed. Our aim is to quantify the frequency of short-term adverse outcomes of children with isolated skull fractures. METHODS PubMed, EMBASE, the Cochrane Library, Scopus, Web of Science, and gray literature were systematically searched to identify studies reporting on short-term adverse outcomes of children aged 18 years or younger with linear, nondisplaced, isolated skull fractures (ie, without traumatic intracranial injury on neuroimaging). Two investigators independently reviewed identified articles for inclusion, assessed quality, and extracted relevant data. Our primary outcome was emergency neurosurgery or death. Secondary outcomes were hospitalization and new intracranial hemorrhage on repeated neuroimaging. Meta-analyses of pooled estimate of each outcome were conducted with random-effects models, and heterogeneity across studies was assessed. RESULTS Of the 587 studies screened, the 21 that met our inclusion criteria included 6,646 children with isolated skull fractures. One child needed emergency neurosurgery and no children died (pooled estimate 0.0%; 95% confidence interval [CI] 0.0% to 0.0%; I2=0%). Of the 6,280 children with known emergency department disposition, 4,914 (83%; 95% CI 71% to 92%; I2=99%) were hospitalized. Of the 569 children who underwent repeated neuroimaging, 6 had new evidence of intracranial hemorrhage (0.0%; 95% CI 0.0% to 9.0%; I2=77%); none required operative intervention. CONCLUSION Children with isolated skull fractures were at extremely low risk for emergency neurosurgery or death, but were frequently hospitalized. Clinically stable children with an isolated skull fracture may be considered for outpatient management in the absence of other clinical concerns.

Abstract
The presence of patients with diverse pathologies in hospitals results in an environment that can be rich in various microorganisms including respiratory and enteric viruses, leading to outbreaks in hospitals or spillover infections to the community. All hospital patients are at risk of nosocomial viral infections, but vulnerable groups such as older adults, children and immuno-compromised/-suppressed patients are at particular risk of severe outcomes including prolonged hospitalization or death. These pathogens could transmit through direct or indirect physical contact, droplets or aerosols, with increasing evidence suggesting the importance of aerosol transmission in nosocomial infections of respiratory and enteric viruses. Factors affecting the propensity to transmit and the severity of disease transmitted via the aerosol route include the biological characteristics affecting infectivity of the viruses and susceptibility of the host, the physical properties of aerosol particles, and the environmental stresses that alter these properties such as temperature and humidity. Non-specific systematic and individual-based interventions designed to mitigate the aerosol route are available although empirical evidence of their effectiveness in controlling transmission of respiratory and enteric viruses in healthcare settings are sparse. The relative importance of aerosol transmission in healthcare setting is still an on-going debate, with particular challenge being the recovery of infectious viral bioaerosols from real-life settings and the difficulty in delineating transmission events that may also be a result of other modes of transmission. For the prevention and control of nosocomial infections via the aerosol route, more research is needed on identifying settings, medical procedures or equipment that may be associated with an increased risk of aerosol transmission, including defining which procedures are aerosol-generating; and on the effectiveness of systematic interventions on aerosol transmission of respiratory and enteric viruses in healthcare settings.

Abstract
Introduction The benefits of rotavirus (RV) vaccination in developed countries have focused on reductions in mortality, hospitalization and medical visits, and herd protection. We investigated other aspects related to RV-induced nosocomial infection, duration of hospital stay, age shift, and sustained vaccine impact (VI) over time. Method RotaBIS (Rotavirus Belgian Impact Study; ClinicalTrials.gov identifier, NCT01563146) annually collects retrospective data on hospitalization linked to RV testing in children up to 5 years old from 11 pediatric wards located all over Belgium. Data from 2005 to 2012 have been split in pre- (2005–2006) and post-vaccination (2007–2012) period. Information was collected on age, gender, RV test result, nosocomial infection caused by RV and duration of hospital stay. Results Over the 6-year period after the introduction of the RV vaccine, an 85% reduction in nosocomial infections was observed (221 in 2005 to 33 in 2012, p < 0.001). A significant reduction of almost 2 days in average duration of hospital stay per event was observed overall (7.62 days in 2005 to 5.77 days in 2012, p < 0.001). The difference is mainly explained by the higher reduction in number of nosocomial infections. A pronounced age shift (+24%, p < 0.01) of RV nosocomial infection to infants ≤2 months old was observed, increasing with length of post-vaccination period. VI was maintained over the follow-up (±79% VI per birth cohort). A decrease was seen depending on age, 85% (95% CI 76–91%) in the youngest to 63% (95% CI 22–92%) in the oldest age group. Conclusion The higher reduction in nosocomial infection may affect the overall average duration of hospital stay for RV infection. No change in VI by birth cohort, but a reduction by age group was observed. These findings could be important for decision-makers considering the introduction of universal mass RV vaccination programs. Trial registration ClinicalTrials.gov identifier,

Abstract
Rotavirus and norovirus are important etiologies of gastroenteritis among hospitalized children. During 2012–2013, we tested 207 residual stool specimens from children with healthcare-associated vomiting and/or diarrhea for rotavirus and norovirus. Twenty (10%) were rotavirus positive, and 3 (3%) were norovirus positive, stressing the importance of these pathogens in hospitalized children.

Abstract
Rotavirus (RV) is worldwide considered as the most important viral agent of acute gastroenteritis in children less than 5 y. Since 2006, the availability of anti-RV vaccines has deeply modified the incidence and economic burden of RV infection. In Europe, some countries have introduced an anti-RV vaccination program in the last 10 y. Although community acquired RV (CARV) disease is the most studied condition of RV infection, recently some authors have highlighted the importance of nosocomial RV (nRV) disease as an emerging public health issue. The aim of this review is to summarize the epidemiology of both CARV and nRV, in order to discuss the difficulty of a clear evaluation of the burden of the disease in absence of comparable data. In particular, we focused our attention to European studies regarding nRV in terms of divergences related to definition, report of incidence rate and methodological issues.

Abstract
Background and Purpose Transient global amnesia (TGA) is a stereotypic condition characterized by anterograde and retrograde amnesia that typically resolves within 24 hours. The pathophysiology of TGA is still unclear. We noted that patients hospitalized with TGA tend to appear in seasonal clusters, and decided to investigate this phenomenon. Methods Every patient with acute presentation of amnesia at our medical center is hospitalized for observation and evaluation. We reviewed the monthly occurrence of TGA in our patient population between 2000 and 2014, and compared this to non-TGA hospitalizations during the same time period. Results During the analysis period, 154 patients who met the criteria for TGA were hospitalized, as well as 259,007 non-TGA hospitalizations. The annual occurrence of TGA ranged from 5 to 16 hospitalizations. There were 91 TGA events in women and 63 in men, in subjects aged 62.8±10.6 years (mean±SD). The incidence was maximal during December [odds ratio (OR)=2.83, 95% confidence interval (CI)=1.20–6.67] and March (OR=2.77, 95% CI=1.17–6.56), and minimal from April to August. The incidence exhibited an increase followed by a decrease from October to February. A seasonal trend was observed as well, with incidence peaks occurring in winter (OR=1.82, 95% CI=1.12–2.96) and spring (OR=1.80, 95% CI=1.10–2.94). Conclusions Our findings suggest that the incidence of TGA exhibits seasonal variations. This observation may help to improve the understanding of the pathophysiology underlying TGA.

Abstract
BACKGROUND Norway has initiated a publicly funded rotavirus immunization program for all age-eligible children in 2014. We aimed to estimate the healthcare costs of rotavirus gastroenteritis in children younger than 5 years old. METHODS We identified all gastroenteritis cases in children younger than 5 years old treated during 2009-2013 through the national claims database for primary care and the national hospital registry. We estimated direct medical costs of rotavirus-associated primary care consultations and hospital encounters (inpatient admission, outpatient visit and ambulatory care). We performed a range of one-way sensitivity analyses to explore uncertainty in the cost estimates. RESULTS Before vaccine introduction, the mean healthcare cost of rotavirus gastroenteritis in children younger than 5 years old was €4,440,337 per year. Among rotavirus-associated costs, 92% were hospital costs and the remaining 8% were primary care costs. The mean annual cost of rotavirus-associated hospital encounters was €4,083,691, of which 95% were costs of inpatient hospital admissions. The average healthcare cost of medically attended gastroenteritis in children younger than 5 years old was approximately €8 million per year, of which rotavirus-related costs represented 56%. CONCLUSIONS Healthcare costs of rotavirus gastroenteritis in Norway are substantial. The cost-effectiveness of ongoing rotavirus immunization program should be reassessed.

Abstract
INTRODUCTION The perineal adhesive bag is the most used method in our country for urine culture collection in infants, despite having a high risk of contamination and false-positive results. We aim to quantify both types of risks through a systematic review. METHODS Search updated in May 2014 in PUBMED, SCOPUS (includes EMBASE), IBECS; CINAHL, LILACS AND CUIDEN, without language or time limits. Percentages of contaminated urines, false positives, sensitivity and specificity (with respect to catheterization or bladder puncture) were recorded. RESULTS A total of 21 studies of medium quality (7,659 samples) were selected. The pooled percentage of contaminated urines was 46.6% (15 studies; 6856 samples; 95% confidence interval [95% CI]: 35.6 to 57.8%; I(2): 97.3%). The pooled percentage of false positives was 61.1% (12 studies; 575 samples; 95% CI: 37.9 to 82.2%; I(2): 96.2%). Sensitivity (88%; 95% CI: 81-93%; I(2): 55.2%), and specificity (82%; 95% CI: 75-89%; I(2): 41.3%) were estimated in five studies, but without including contaminated urines. CONCLUSION The perineal adhesive bag is not a valid enough method for urine culture collection, because almost half are contaminated and, if they are positive, two out of three are false. Although these estimates are imprecise, because of their great heterogeneity, they should be considered when choosing the method of urine collection. The estimates of sensitivity and specificity are not applicable because they do not take into account the risk of contamination.

Abstract
Although viruses are well-established causes of acute gastroenteritis, few data on the circulation of these pathogens in Porto Velho, state of Rondônia, Brazil, are available. Thus, faecal samples from hospitalised diarrhoeic children, under six years of age, were collected and tested for the presence of norovirus (NoV), adenovirus (AdV) and astrovirus (AstV) from February 2010-February 2012. Specimens were screened by reverse-transcription polymerase chain reaction and viruses were found in 10.7% (63/591) of the cases. NoV, AdV and AstV were detected in 7.8%, 2% and 0.8% of the samples, respectively. NoV infection was observed at all ages and was most prevalent in zero-18-month-old children (84.7%; p = 0.002). A higher incidence of NoV was detected from February-April 2010, when it was found in 52.2% of the cases. Co-infections involving these viruses, rotavirus and enteropathogenic bacteria were detected in 44.4% (28/63) of the children with viral diarrhoea. Nosocomial infections were demonstrated in 28.6% (18/63) of the cases in which viruses were detected. The present paper reports, for the first time, the circulation of NoV and AstV among the paediatric population of Porto Velho and it contributes to our understanding of the roles of these pathogens in gastrointestinal infections.

Abstract
Background Systematic reviews (SRs) are expected to critically appraise included studies and privilege those at lowest risk of bias (RoB) in the synthesis. This study examines if and how critical appraisals inform the synthesis and interpretation of evidence in SRs. Methods All SRs published in March–May 2012 in 14 high-ranked medical journals and a sample from the Cochrane library were systematically assessed by two reviewers to determine if and how: critical appraisal was conducted; RoB was summarised at study, domain and review levels; and RoB appraisals informed the synthesis process. Results Of the 59 SRs studied, all except six (90%) conducted a critical appraisal of the included studies, with most using or adapting existing tools. Almost half of the SRs reported critical appraisal in a manner that did not allow readers to determine which studies included in a review were most robust. RoB assessments were not incorporated into synthesis in one-third (20) of the SRs, with their consideration more likely when reviews focused on randomised controlled trials. Common methods for incorporating critical appraisals into the synthesis process were sensitivity analysis, narrative discussion and exclusion of studies at high RoB. Nearly half of the reviews which investigated multiple outcomes and carried out study-level RoB summaries did not consider the potential for RoB to vary across outcomes. Conclusions The conclusions of the SRs, published in major journals, are frequently uninformed by the critical appraisal process, even when conducted. This may be particularly problematic for SRs of public health topics that often draw on diverse study designs.

Abstract
BACKGROUND Nosocomial outbreaks of viral etiology are costly and can have a major impact on patient care. Many viruses are known to persist in the inanimate environment and may pose a risk to patients and health care workers. We investigate the frequency of environmental contamination with common health care-associated viruses and explore the use of torque-teno virus as a marker of environmental contamination. METHODS Environmental screening for a variety of clinically relevant viruses was carried out over 3 months in a UK pediatric hospital using air sampling and surface swabbing. Swabs were tested for the presence of virus nucleic acid by quantitative polymerase chain reactions. RESULTS Viral nucleic acid was found on surfaces and in the air throughout the screening period, with adenovirus DNA being the most frequent. Door handles were frequently contaminated. Torque-teno virus was also found at numerous sites. CONCLUSION Evidence of environmental contamination with viral pathogens is present in health care environments and may be indicative of an infectious virus being present. Screening for viruses should be included in infection control strategies. Torque-teno virus may provide a better marker of contamination and reduce time and cost of screening for individual viruses.

Abstract
Two licensed vaccines are available to prevent RVGE in infants. A worldwide critical review of economic evaluations of these vaccines was conducted. The objective was to describe differences in methodologies, assumptions and inputs and determine the key factors driving differences in conclusions. 68 economic evaluations were reviewed. RV vaccination was found to be cost-effective in developing countries, while conclusions varied between studies in developed countries. Many studies found that vaccination was likely to be cost-effective under some scenarios, such as lower prices scenarios, inclusion of herd protection, and/or adoption of a societal perspective. Other reasons for variability included uncertainty around healthcare visits incidence and lack of consensus on quality of life (QoL) valuation for infants and caregivers. New evidence on the vaccination effectiveness in real-world, new ways of modeling herd protection and assessments of QoL in children could help more precisely define the conditions under which RV vaccination would be cost-effective in developed countries.

Abstract
The NSP4 protein is a multifunctional protein that plays a role in the morphogenesis and pathogenesis of the rotavirus. Although NSP4 is considered an enterotoxin, the relationship between gastroenteritis severity and amino acid variations in NSP4 of the human rotavirus remains unclear. In this study, we analyzed the sequence diversity of NSP4 and the severity of gastroenteritis of children with moderate to severe gastroenteritis. The rotavirus-infected children were hospitalized before the rotavirus vaccine program in Mexico. All children had diarrhea within 1-4 days, 44 (88%) were vomiting and 35 (70%) had fevers. The severity analysis showed that 13 (26%) cases had mild gastroenteritis, 23 (46%) moderate gastroenteritis and 14 (28%) severe. NSP4 phylogenetic analysis showed three clusters within the genotype E1. Sequence analysis revealed similar mutations inside each cluster, and an uncommon variation in residue 144 was found in five of the Mexican NSP4 sequences. Most of the amino acid variations were located in the VP4 and VP6 binding site domains, with no relationship to different grades of gastroenteritis. This finding indicates that severe gastroenteritis caused by the rotavirus appears to be related to diverse viral or cellular factors instead of NSP4 activity as a unique pathogenic factor.

Abstract
In Germany, routine RV-vaccination is not adopted into the national immunization schedule as of 2012. Because RV-vaccines were already on the market since 2006, in 2010 a moderate (58%) and low (22%) vaccine uptake was observed in the 5 eastern federal states (EFS) and the 11 western federal states (WFS), respectively. To assess the impact of RV-vaccination, we compared the incidence rates (IR) of RV-related hospitalizations before (2004‒2006) and in seasons after (2008/09-2010/11) RV-vaccine introduction in Germany by utilizing data from the national mandatory disease reporting system. In the EFS, the IR was significantly reduced in age-groups < 18 mo in 2008/09 and in age-groups < 24 mo in 2009/10-2010/11. In the WFS an IR-reduction was observed only in age-groups < 12 mo in 2008/09 and in age-groups < 18 mo in 2009/10-2010/11. Overall IR-reduction in age-groups < 24 mo comparing 2008-11 with 2004-06 was 36% and 25% in EFS and WFS, respectively. In addition, we computed IR-ratios (IRR) in the seasons after mid-2006 with negative binomial regression. The effect of vaccination was independent from the geographic region. Vaccination was associated with a significant reduction in RV-related hospitalizations in the age-groups 6-23 mo. Most prominently, vaccination of 50% of infants led to an estimated decrease in age group 6-11 mo by 42%. No significant reduction was observed in age-groups ≥ 24 mo. In conclusion, in the German setting with low to moderate vaccine uptake, RV-related hospitalization incidence decreased substantially depending on the achieved vaccination coverage, but only in the first two years of life.
