A 7-Year Survey (2015-2021) in One Pediatric Hospital (Brasov, Romania) on Rotavirus Gastroenteritis Specified as Community- or Hospital-Acquired Infection in Young Children. Trop Med Infect Dis 2023; 8:509. [PMID: 38133441 PMCID: PMC10747557 DOI: 10.3390/tropicalmed8120509] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Revised: 11/16/2023] [Accepted: 11/22/2023] [Indexed: 12/23/2023] Open
Abstract
This project is an observational, descriptive study evaluating frequencies of rotavirus disease in hospitalized children aged less than 5 years old between 2015 and 2021 in the Pediatric Hospital of Brasov, Central Romania. The study compares socio-demographic (age, sex, place of living and ethnicity), clinical, and treatment aspects between community-acquired rotavirus gastroenteritis (CARG) and hospital-acquired rotavirus gastroenteritis (HARG). During that period, 1913 hospitalized children had a rapid positive immunichromatographic rotavirus test from stool specimens. Among them, 1620 (84.6%) were CARG and 293 (15.4%) were HARG. CARG conditions represented 28.5% of all acute hospitalized gastroenteritis (n = 5673) whereas HARG represented 5.2%. Around the same percentage of urban children were seen in CARG as in HARG (58.5% (n = 948) for CARG and 56.3% (n = 164) for HARG). About 64.9% (n = 1052) of CARG cases were from Roma population, and 66.5% (n = 195) in HARG. The age group with the highest frequency of the disease was 12 to 24 months old for both CARG and HARG. The average hospital duration was 5.09 days for CARG and 7.62 days for HARG. Diarrhea was the principal symptom in both CARG and HARG (92.6% (n = 1500) for CARG and 93.9% (n = 275) for HARG). Most CARG patients (61% (n = 989)) were treated for symptomatic management with iv fluids. Most HARG (60.4% (n = 177)) were treated for symptomatic management with iv fluids and antibiotics. A significant seasonal shift to a later period in the year was observed during the last registration year of 2021, possibly due to the COVID-19 epidemic. The seasonal disease burden of rotavirus infection in children remains high in hospital care in Romania, which may justify the systematic introduction of rotavirus vaccination across the whole country.

Abstract
Community-acquired infections (CAI) can affect the duration of care and mortality of patients. Therefore, we aimed to investigate these as well as factors influencing the length of hospital stay in patients with CAI due to enteric pathogens, influenza viruses and multidrug-resistant (MDR) bacteria. We obtained data on 531 patients with CAI from the medical databases of a Hungarian university hospital and analyzed their characteristics using a regression model. Patients with MDR bacterial infection had the highest mortality (26.24%) and they stayed significantly longer in the hospital than cases with other CAIs. Our results showed that infection by Clostridioides difficile (odds ratio (OR): 6.98, 95% confidence interval (CI): 1.03-47.48; p = 0.047), MDR Escherichia coli (OR: 7.64, 95% CI: 1.24-47.17; p = 0.029), MDR Klebsiella spp. (OR: 7.35, 95% CI: 1.15-47.07; p = 0.035) and hospitalization in the department of pulmonology (OR: 5.48, 95% CI: 1.38-21.76; p = 0.016) and surgery (OR: 4.19, 95% CI: 1.18-14.81; p = 0.026) significantly increased, whereas female sex (OR: 0.62, 95% CI: 0.40-0.97; p = 0.037) and hospitalization in the department of pediatrics (OR: 0.17, 95% CI: 0.04-0.64; p = 0.009) decreased the odds of staying in the hospital for more than 6 days. Our findings provide new information on the epidemiology of CAI and can contribute to the development of public health programs that decrease the burden of infections acquired in the community.

Abstract
Acute gastroenteritis is the cause of considerable mortality and morbidity worldwide, particularly among children under five years in underdeveloped countries. Most acute gastroenteritis (AGE) cases are attributed to viral etiologies, including rotavirus, norovirus, adenovirus, astrovirus, and sapovirus. This paper aimed to determine the prevalence rate of different viral etiologies of AGE in the Middle East and North Africa (MENA) region. Moreover, this paper explored rotavirus phylogenetic relatedness, compared VP7 and VP4 antigenic regions of rotavirus with vaccine strains, and explored the availability of vaccines in the MENA region. The literature search identified 160 studies from 18 countries from 1980 to 2019. The overall prevalence of rotavirus, norovirus, adenovirus, astrovirus, and sapovirus were 29.8 %, 13.9 %, 6.3 %, 3.5 %, and 3.2 % of tested samples, respectively. The most common rotavirus genotype combinations in the MENA region were G1P[8], G9P[9], and G2P[4], whereas GII.4 was the predominant norovirus genotype all of which were reported in almost all the studies with genotyping data. The comparison of VP7 and VP4 between circulating rotavirus in the MENA region and vaccine strains has revealed discrete divergent regions, including the neutralizing epitopes. Rotavirus vaccine was introduced to most of the countries of the MENA region; however, only a few studies have assessed the effectiveness of vaccine introduction. This paper provides a comprehensive update on the prevalence of the different viral agents of AGE in the MENA region.

Abstract
BACKGROUND Rotavirus is a common cause of acute gastroenteritis in young children in the Netherlands, where rotavirus vaccination has not yet been implemented. OBJECTIVES To evaluate a difference in illness severity course depending on the presence of rotavirus infection and assess the prevalence of viruses and the referral rate in children with acute gastroenteritis. METHODS A prospective cohort of children aged 6 months to 6 years presenting with acute gastroenteritis to a primary care out-of-hours service from October 2016 to March 2018. Faeces were sampled and sent to a laboratory where viral pathogens were identified and quantified by real-time polymerase chain reaction. Severe course of acute gastroenteritis was defined as a Modified Vesikari Score of ≥11. In addition, we assessed referral rates. Chi-square tests were used to evaluate differences between groups. RESULTS We included 75 children (34 boys) with a median age of 1.5 years (interquartile range, 0.9-2.0 years). The prevalence of rotavirus was 65.3% (95% confidence interval, 53.5-76.0) with a median cycle threshold of 16.0. Severe course of acute gastroenteritis was present in 31 of 71 children (4 were lost to follow-up). Those with rotavirus (20/47) did not have a severe course more often than those without (11/24): odds ratio, 0.88 (95% confidence interval, 0.33-2.36). Referral rates were comparable for rotavirus (15.2%) and non-rotavirus (14.3%). CONCLUSION In out-of-hours primary care, rotavirus is common but not associated with increased severity and higher referral rates in children with acute gastroenteritis.

Abstract
The study aim was to examine possible correlates of convulsions in children hospitalized for acute gastroenteritis (AGE). Data collected in a prospective study of AGE hospitalizations in children aged 0-59 months in 3 hospitals in Israel during 2008-2015 were analyzed. Stool samples were tested for rotavirus using immunochromatography and stool culture was performed for the detection of Salmonella, Shigella and Campylobacter We compared clinical and demographic characteristics of children hospitalized for AGE who had convulsions (n = 68, cases) with children hospitalized for AGE without convulsions (n = 3505, controls). Age differed between children with and without convulsions (p = 0.005); the former were mostly toddlers aged 12-23 months (51%) compared to 30% of the control group. A higher percentage of cases tested positive for Shigella (11% vs. 4%, p = 0.002), the opposite was found for rotavirus (2% vs. 30% p < 0.001). A multivariable model showed that body temperature (OR 2.91 [95% CI 1.78-4.76], p < 0.001) and high blood glucose level (> 120 mg/dL) (OR 5.71 [95% CI 1.27-25.58] p = 0.023) were positively related to convulsions in children with AGE, while severe AGE (Vesikari score ≥ 11) was inversely related with convulsions (OR 0.09 [95% CI 0.03-0.24], p < 0.001). Conclusion: Elevated body temperature is associated with convulsions in children with AGE, but not severity of AGE, while hyperglycemia might reflect a neuroendocrine stress reaction to convulsions, AGE or both.

Abstract
AIM We examined the impact of insertion of the Rotavirus vaccine (RVV) into the Israeli National Immunisation Programme (NIP) on hospitalisations due to both acute gastroenteritis (AGE) and Rotavirus gastroenteritis (RVGE) in children. METHODS We retrospectively analysed the medical records of children aged <5 years admitted with a diagnosis of AGE between 2008 and 2016 in two children's hospitals in central Israel. Clinical, laboratory, microbiological data and RV immunisation status were retrieved. Data were compared before and after the introduction of the RVV into the NIP. RESULTS A total of 2042 children were admitted with AGE. Hospitalisations due to AGE and RVGE decreased from 3310 to 1950 and from 1027 to 585 per 100 000 admissions, respectively, after the RVV (relative risk reduction (RRR) of 41% and 43%, respectively). RV remained the most common pathogen in both study periods. There was no significant difference in the clinical course between immunised and non-immunised children admitted with RVGE. CONCLUSION The introduction of the RVV to the NIP significantly reduced the admissions due to both AGE and RVGE in children <5 years. However, RV is still the most common agent for admissions due to AGE in this age group.

Abstract
Rotavirus (RV) vaccines have been available in Turkey since 2006. These vaccines are not funded by the National Health System, so consequently their coverage rate in children has reached only 13-18%. We conducted a retrospective record review including all children ≤60 months of age presenting to study hospitals with suspected or clinical acute gastroenteritis (AGE) between 2012 and 2018. During the study, 109,605 children ≤60 months of age were admitted to pediatric out-patient clinics and pediatric emergency room, of which 15,501 (14%) were diagnosed with AGE. Incidence of RV-positive AGE decreased from 4.47 per 1,000 children in 2012 to 2.48 per 1,000 in 2018. A total of 4,805 (31%) such children were hospitalized with RV-positive AGE, a decrease from 1.9 per 1,000 children in 2012 to 0,45 per 1,000 in 2018. The length of hospital stays (LOS) of RV-positive AGE was 2.47 ± 1.15 days compared to LOS of RV-negative AGE 1.59 ± 1.17 days (p < .001). The overall cost of RV-positive AGE ($335 ± 200) was higher than that for RV-negative AGE ($280 ± 148) cases (p = .015). Vaccine effectiveness against any case of RV-positive AGE was 75,1% (95% CI: 65-86%). Despite the low level of vaccine coverage, the introduction of RV vaccination had a positive impact on the incidence of RV-positive AGE and related hospitalizations in young children.

Abstract
Acute gastroenteritis (AGE) remains a major cause of diarrhea in developing and developed countries. Rotavirus (RV) is a leading cause of severe pediatric diarrhea worldwide. Here we report on the prevalence of circulating genotypes in association with demographics and clinical manifestations outcomes in Qatar. A total of 231 RV-positive fecal samples were collected from children suffering from AGE during 3 years study period between June 2016 and June 2019. The age of the subjects ranged between 2 months and 14 years (median of 16 months). The VP4 and VP7 were amplified and sequenced. Phylogenetic analyses were performed using MEGA7.0. Pearson's chi-squared test was used to determine significant differences for comparisons of general categorical variables. RV infections were most common in children between 1 and 3 years of age (49%), followed by those < 1 year and > 3 years of age (33% and 28%, respectively). RV infections were more frequent in males than females, with a ratio of 1.4:1. RV infections occurred throughout the year, with a noticeable increase in summer (42.8%) and a drop in winter (20.1%). RV genotypes G3P[8] (30.8%), G2P[8] (12.3%), G4P[8] (11.7%), and G1P[8] (10.4%) were the common genotypes during the study period. The G3P[8] strain detected in our study revealed similarities to the equine-like G3P[8] (10.3%; 24/231) (KT988229.1), Wa-like genomic constellation (9%; 21/231) (MF563894.1), and DS-1-like strains (6.4%; 15/231) (LC386081.1). Based on the Vesikari score system, severe clinical illness including diarrhea and vomiting (average frequency: 4 to 5 times/day) was recorded for G3P[8] group, followed by G9P[8], G4P[8], and G1P[8]. Higher incidence for G3P[8], G2P[8], G4P[8], and G1P[8] were reported in Qatari subjects compared to other nationalities. The multinational status of a small country explains the wide diversity of circulating RV genotypes in Qatar. The highest prevalence and severe illnesses were recorded to G3P[8], which is different from other surrounding countries/global levels.

Effects of rotavirus vaccine on all-cause acute gastroenteritis and rotavirus hospitalizations in Israel: A nationwide analysis. Vaccine 2020; 38:2406-2415. [PMID: 32029322 DOI: 10.1016/j.vaccine.2020.01.034] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2019] [Revised: 11/26/2019] [Accepted: 01/09/2020] [Indexed: 11/21/2022]
Abstract
BACKGROUND In December 2010, the pentavalent rotavirus vaccine (RotaTeq) was added to the national immunization program in Israel. The study aim was to examine national reductions in all-cause acute gastroenteritis (AGE) and rotavirus gastroenteritis (RVGE) hospitalizations among children aged 0-59 months following the introduction of universal rotavirus immunization in Israel. METHODS We extracted data from the Israel National Hospital Discharge Database. Hospitalization rates were calculated by dividing the annual number of all-cause AGE and RVGE hospitalizations by the number of children aged 0-59 months residing Israel. To assess rate reductions, we compared the mean hospitalization rate for the pre-vaccine years (2002-2008) with that for the universal vaccination years (2011-2017). Interrupted time-series analyses were undertaken. During 2008-2010 rotavirus vaccines were partially available. RESULTS A total of 131,116 AGE hospitalizations were reported, of which 13,111 (10.0%) were coded as RVGE hospitalizations. The average annual all-cause AGE hospitalization rate during the pre-vaccine period was 147.9 (95% CI 146.7-149.0) per 10,000 children aged 0-59 months, and declined by 38.7-53.0% during the universal vaccination years. The average annual pre-vaccine RVGE hospitalization rate was 16.9 (95% CI 16.5-17.3) per 10,000 children, and declined by 89.1% during 2016-2017. Findings from interrupted time-series analyses showed significant impact of introducing universal rotavirus immunization on the declines of all-cause AGE and RVGE hospitalizations rates. A multivariable Autoregressive Integrated Moving Average model showed that the variable "immunization period" was a significant predictor of RVGE hospitalizations (t = 7.3, p < 0.001) for the universal vaccination years. The declines in hospitalizations rates of all-cause AGE were lower among Arab children compared to Jewish children, but the declines in RVGE rates were similar between the groups. CONCLUSIONS National hospitalization data demonstrated substantial and consistent reductions in all-cause AGE and RVGE hospitalizations following the implementation of universal rotavirus vaccination program.

Abstract
Following the introduction of universal immunization against rotavirus, concerns were raised regarding pathogen-replacement of rotavirus by norovirus. The study aim was to examine the incidence and characteristics and norovirus gastroenteritis before and after the introduction of universal rotavirus immunization in Israel. We studied 1179 stool samples collected between November 2007 and December 2014 for a prospective hospital-based surveillance study of children aged 0-59 months hospitalized for gastroenteritis. A real-time RT-PCR assay was used to identify genogroup II (GII) norovirus in extracted fecal RNA samples. Overall, the weighted percentage of norovirus positive patients was 10.9%. Norovirus positivity was similar in the pre-universal rotavirus immunisation years (2008-2010) and the universal years (2011-2014), the respective average annual incidence of norovirus gastroenteritis was 1.6 (95% CI 0.6-2.3) per 1000 and 1.1 (95% CI 0.8-1.4) per 1000 children. Rotavirus was detected in 36.8% and 19.6% of the patients in the pre-vaccine years and the universal vaccine years, with an estimated incidence of 5.5 (95% CI 3.4-7.6) per 1000 and 2.1 (95% CI 1.6-2.7) per 1000 children, respectively. Most patients (59.1%) with norovirus gastroenteritis were infants aged 0-11 months. Norovirus was detected all year round with a significant 3-month peak from September through November. In conclusion, norovirus continues to be a leading cause of acute gastroenteritis associated with hospitalizations in young children. Future norovirus vaccines should target young infants. There was no evidence of pathogen-replacement by norovirus following the introduction of universal rotavirus immunization in Israel.

Abstract
Advent of new strains and shift in predominantly circulating genotypes are characteristics of group- A rotavirus (RVA), one of the major causes of childhood gastroenteritis. During diarrheal disease surveillance at Kolkata, India (2014-2016), a shift in circulating RVA strains from G1P[8] to G3P[8] was seen. Stool samples from children (n = 3048) with acute gastroenteritis were tested of which 38.7% were RVA positive. G1 was the predominant strain (65.3%) in 2014-2015 whereas in late 2015 and 2016, G3 became the preponderant strain (44.6%). In the past decade G3 strains were not observed in this region, we conducted whole genome sequencing of representative strains to gain insight into the phenomenon of emergence and genetic constellation of these circulating human G3 strains. The analyses revealed intergenogroup reassortment in G3P[4] strains (among Wa and DS-1-like genogroup) whereas G3P[8] strains were authentic Wa-like. Phylogenetic analysis revealed Kolkata G3 strains as polymorphic and thus they formed two sub-clusters due to antigenic differences in their VP7 protein. One of the sub-clusters had the wild-type threonine at 87 amino acid position while another sub-cluster had an isoleucine mutation. Presence of additional N-linked glycosylation site at amino acid 283 of VP7 glycoprotein suggests that the major neutralizing epitope on the VP7 (G3) of RotaTeq vaccine differs from the currently circulating G3 strains. The study is important as efficiency of rotavirus vaccine depends on the circulating heterogeneous genotype constellations. Continuous monitoring of circulating RVA strains in endemic settings like India is therefore important in pre- and post-vaccination period to monitor the emergence of new reassortant genotypes in addition to assessing vaccine efficacy.

Abstract
Rotavirus (RV) is the leading cause of severe acute gastroenteritis (AGE) worldwide. Consequently, we conducted a systematic literature review on articles studying RV in the 25 countries of the MENA region during the past 15years (2000-2015). The methods and reporting were set according to the 2015 preferred reporting items for systematic review and meta-analysis protocols (PRISMA-P) and based on the elements from the international prospective register of systematic reviews (PROSPERO). Our literature search identified 169 studies meeting our predefined inclusion criteria. Studies reporting on RV were conducted in 19 out of the 24 countries of the MENA region. The largest number of studies was reported in Turkey (n=32), Iran (n=31), Saudi Arabia (n=19) and Egypt (n=17). The majority of studies reporting on RV gastroenteritis rates were clinical observational studies. In 115 studies out of 169, RV was reported among in-patients whereas 35 studies reported RV among outpatients. The predominantly reported RV genotype in the region was G1[P8] followed by G2[P4] and G9[P8]. The majority of studies (n=108) were conducted among children less than 5years of age whereas the remaining studies reported on AGE among other age groups and rarely adults. In MENA countries, RV infection was reported all year round with peaks described in cold as well as hot months. This systematic review provides a current update on the epidemiology of RV-associated gastroenteritis in countries of the MENA region and draws attention to the major gaps existing in the continuous monitoring of RV.

Abstract
We present an overview of the impact of universal rotavirus immunization with the pentavalent vaccine, RotaTeq, which was introduced in Israel in 2010. The vaccine is given free of charge at age 2, 4 and 6 months, with an 80% coverage that was shortly achieved during the universal immunization period. Compared to pre-universal immunization years (2008-2010), a reduction of 66-68% in the incidence of rotavirus gastroenteritis (RVGE) hospitalizations was observed in 2011-2015 among children aged 0-23 months in central and northern Israel. In southern Israel a reduction of 80-88% in RVGE hospital visit rate was found among Jewish children aged 0-23 months in 2011-2013. Among Bedouins, the respective decline was 62-75%. A significant reduction of 59% was also observed in RVGE clinic visits, presumably representing less severe illness. Indirect benefit was evident in children aged 24-59 months who were ineligible for universal immunization. Vaccine effectiveness against RVGE hospitalization was estimated at 86% in children aged 6-23 months. Changes in the circulating rotavirus genotypes occurred but the contribution of vaccine induced immune pressure is unclear. Universal rotavirus immunization was followed by an impressive decrease in the burden of RVGE in young children in Israel, likely attributed to good vaccine coverage and effectiveness.

Abstract
BACKGROUND Uncertainty exists about the sustainability of the reduction in rotavirus gastroenteritis (RVGE) following the introduction of rotavirus vaccines into national immunization programs, and on its potential impact on circulating genotypes. RotaTeq was introduced into the Israeli national immunization program in December 2010, and vaccination coverage is around 80%. AIMS To examine the change in incidence of RVGE hospitalization and rotavirus genotypes, during the five years after introduction of RotaTeq into the Israeli national immunization program. METHODS Data were obtained prospectively on hospitalization of children aged 0-59months due to acute gastroenteritis (N=7346) from three hospitals in northern Israel. Stool samples were tested for rotavirus by immunochromatography. Rotavirus was genotyped (N=506) by RT-PCR and/or sequencing. RESULTS The average incidence of RVGE hospitalization declined by 61.0% (95% CI 49.0-73.4%), from 5.6 per 1000 (95% CI 5.0-6.2) in the pre-universal immunization period (2008-2010) to 2.2 per 1000 (95% CI 1.8-2.5) during the universal immunization period (2012-2015), but yearly fluctuations were still observed. The most common genotypes in the pre-universal immunization period were G1P[8] (35.3%) followed by G2P[4] (15.5%), G3P[8] (8.8%), G4P[8] (4.3%) and G9P[8] (4.3%), and 19.5% were mixed infections. The dominance of G1P[8] continued into the universal immunization period (48.6%), followed by G3P[8] (21.5%), G9P[8] (15.9%) and G12P[8] (4.7%), while mixed rotavirus infections were no longer detected. CONCLUSIONS Universal immunization with RotaTeq in Israel was associated a sustained reduction in RVGE hospitalization. It is unclear whether changes in the circulating rotavirus genotypes are due to vaccine-induced selective pressure. Assessment of the long-term impact of rotavirus vaccination on the incidence of rotavirus gastroenteritis and continued strain surveillance is warranted.

Abstract
Species A rotaviruses (RVA) are the most important cause of acute gastroenteritis in the young of humans and many animal species globally. G1P[8], G2P[4], G3P[8], G4P[8], G9P[6/8] and G12P[6/8] are the predominantly isolated genotypes throughout the world including India. Unusual genotypes from different host species such as G5, G6, G8, G10 and G11 have also been reported in humans with low frequency. In the present study, among >650 RVA positive stool samples collected from children with diarrhea in Kolkata, India, during 2014, two isolates each of the genotype G12P[11] and G10P[14] were obtained and their genomes completely sequenced. The full genotype constellations were G12-P[11]-I1-R1-C1-M2-A1-N1-T2-E1-H1 and G12-P[11]-I1-R1-C1-M1-A5-N1-T1-E1-H1 for G12P[11] viruses, suggesting several reassortments between Wa- and DS-1-like human RVA strains, including possible reassortment of a simian NSP1 gene. The G10P[14] viruses (G10-P[14]-I2-R2-C2-M2-A11-N2-T6-E2-H3) were found to contain multiple genes closely related to RVAs of artiodactyl origin, highlighting the role of inter-host species transmissions of RVAs. From the G/P constellation of all RVA isolates, it could be concluded that approximately one quarter had likely arisen from reassortment events in vivo among RVAs of 'usual' genotypes.

Abstract
Universal rotavirus vaccination with RotaTeq was introduced in Israel in December 2010. We examined hospitalization rates of children under 5 years of age due to all-cause and rotavirus gastroenteritis, both before and 3 years after universal introduction of the vaccination. An ongoing hospital-based surveillance network that was established in November 2007, accessed information regarding hospitalization of children due to gastroenteritis (n = 6205) in 3 hospitals in northern Israel, with an annual average of about 60,000 children under 5 years of age living in the catchment area of these hospitals. Stool samples were tested for rotavirus by immunochromatography. Compared to the period preceding implementation of the universal rotavirus vaccination (2008-2010), hospitalizations due to rotavirus gastroenteritis in children <5 years of age decreased significantly, by 55% (95% CI 43%-67%) during the period of universal vaccination (2011-2013), a decrease that was sustained throughout the 3 year period. This reduction was greater in children aged 0-23 months (60-61%) than in toddlers aged 24-59 months (36%). A 32% (95% CI 21%-45%) decrease in the incidence of all-cause gastroenteritis was also observed. During the period preceding universal vaccination, rotavirus diarrhea showed typical winter seasonality, with highest incidence in December. However, the winter peak was substantially blunted during the period of universal immunization. Surveillance of rotavirus gastroenteritis should continue to assess the long-term impact of such a program. Our findings are of relevance to high and middle-income countries considering the introduction of a universal rotavirus immunization program.

Abstract
Regarding public health in Brazil, a new scenario emerged with the establishment of universal rotavirus (RV) vaccination programs. Herein, the data from the five years of surveillance (2007-2012) of G- and P-type RV strains isolated from individuals with acute gastroenteritis in Brazil are reported. A total of 6,196 fecal specimens were investigated by ELISA and RT-PCR. RVs were detected in 19.1% (1,181/6,196). The peak of RV incidence moved from June-August to September. RV was detected less frequently (19.5%) among children ≤ 5 years than in older children and adolescents (6-18 years) (40.6%). Genotype distribution showed a different profile for each year: G2P[4] strains were most prevalent during 2007-2010, G9P[8] in 2011, and G12P[8] in 2012. Mixed infections (G1+G2P[4], G2+G3P[4]+P[8], G2+G12P[8]), unusual combinations (G1P[4], G2P[6]), and rare strains (G3P[3]) were also identified throughout the study period. Widespread vaccination may alter the RV seasonal pattern. The finding of RV disease affecting older children and adolescents after vaccine implementation has been reported worldwide. G2P[4] emergence most likely follows a global trend seemingly unrelated to vaccination, and G12, apparently, is emerging in the Brazilian population. The rapidly changing RV genotype patterns detected during this study illustrate a dynamic population of co-circulating wildtype RVs in Brazil.

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
Both rotavirus vaccines RotaTeq and Rotarix were efficacious against severe rotavirus gastroenteritis in clinical trials; yet real-world data on the effect of rotavirus vaccines on mild to moderate disease are limited. We used a large computerised database of Maccabi Health Services Health Maintenance Organisation (HMO), the second largest HMO in Israel covering 25% of the Israeli population, to compare the incidence of acute gastroenteritis (AGE) clinic visits in community settings (n = 302,445) before (2005–10) and after (2011–13) the introduction of universal rotavirus immunisation in Israel. We retrieved laboratory results of rotavirus antigen tests (n = 18,133) and using a weighted analysis, we estimated the impact of rotavirus immunisation on the disease burden of rotavirus AGE clinic visits. Following the introduction of universal rotavirus immunisation, the typical winter peaks of rotavirus AGE were substantially lower and significant reductions of 14.8% (95% confidence interval (CI): 13.5–16.1) in all-cause AGE clinic visits and of 59.7% (95% CI: 59.8–62.6) in rotavirus AGE clinic visits were observed. The decrease was observed in all age groups, but it was greater in children aged 0 to 23 months than those aged 24 to 59 months. Continued rotavirus laboratory surveillance is warranted to monitor the sustainability of these changes.

Abstract
Group A rotaviruses (RV) are the major cause of acute gastroenteritis in infants and young children globally. Waterborne transmission of RV and the presence of RV in water sources are of major public health importance. In this paper, we present the Global Waterborne Pathogen model for RV (GloWPa-Rota model) to estimate the global distribution of RV emissions to surface water. To our knowledge, this is the first model to do so. We review the literature to estimate three RV specific variables for the model: incidence, excretion rate and removal during wastewater treatment. We estimate total global RV emissions to be 2 × 1018 viral particles/grid/year, of which 87% is produced by the urban population. Hotspot regions with high RV emissions are urban areas in densely populated parts of the world, such as Bangladesh and Nigeria, while low emissions are found in rural areas in North Russia and the Australian desert. Even for industrialized regions with high population density and without tertiary treatment, such as the UK, substantial emissions are estimated. Modeling exercises like the one presented in this paper provide unique opportunities to further study these emissions to surface water, their sources and scenarios for improved management.

Abstract
Background Bacterial and viral enteric pathogens are the leading cause of diarrhea in infants and children. We aimed to identify and characterize the main human diarrheagenic E. coli (DEC) in stool samples obtained from children less than 5 years of age, hospitalized for acute gastroenteritis in Israel, and to examine the hypothesis that co-infection with DEC and other enteropathogens is associated with the severity of symptoms. Methods Stool specimens obtained from 307 patients were tested by multiplex PCR (mPCR) to identify enteroaggregative E. coli (EAEC), enterohemorrhagic (EHEC), enteropathogenic E. coli (EPEC) and enterotoxigenic E. coli (ETEC). Specimens were also examined for the presence of rotavirus by immunochromatography, and of Shigella, Salmonella and Campylobacter by stool culture; clinical information was also obtained. Results Fifty nine (19%) children tested positive for DEC; EAEC and atypical EPEC were most common, each detected in 27 (46%), followed by ETEC (n = 3; 5%), EHEC and typical EPEC (each in 1 child; 1.5%). Most EAEC isolates were resistant to cephalexin, cefixime, cephalothin and ampicillin, and genotypic characterization of EAEC isolates by O-typing and pulsed-field gel electrophoresis showed possible clonal relatedness among some. The likelihood of having > 10 loose/watery stools on the most severe day of illness was significantly increased among patients with EAEC and rotavirus co-infection compared to children who tested negative for both pathogens: adjusted odds ratio 7.0 (95% CI 1.45-33.71, P = 0.015). Conclusion DEC was common in this pediatric population, in a high-income country, and mixed EAEC and rotavirus infection was characterized by especially severe diarrhea.

Abstract
Background Determining the background incidence of intussusception is important in countries implementing rotavirus immunization. Rotavirus immunization was introduced into the routine infant immunization program in Israel during late 2010. Incidence and risk factors for intussusception were examined in children aged less than five years between 1992 and 2009. Methods Data were collected from medical records of children hospitalized due to intussusception (N = 190), and from control children (N = 295), at Carmel and Hillel Yaffe hospitals in northern Israel. Results The average annual incidence of intussusception in Jewish and Arab children aged less than five years was estimated at 36.1 (95% CI 17.0-76.5) vs. 23.2 per 100,000 (95% CI 9.3-57.9); for infants less than 12 months of age- 128.1 (95% CI 53.0-309.6) vs. 80.1 (95% CI 29.1-242.6) per 100,000. The risk of intussusception was higher in infants aged 3–5 months: OR 5.30 (95% CI 2.11-13.31) and 6–11 months: OR 2.53 (95% CI 1.13-5.62) when compared to infants aged less than 3 months; in those living in low vs high socioeconomic communities: OR 2.81 (95% CI 1.45-5.43), and in children with recent gastroenteritis: OR 19.90 (95% CI 2.35-168.32) vs children without recent gastroenteritis. Surgical reduction was required in 23.2%. The likelihood of surgery was significantly increased in patients presenting with bloody stool, in Arabs and those who were admitted to Hillel Yaffe Hospital. Conclusions The incidence of intussusception prior to universal rotavirus immunization was documented in northern Israel. Despite the lower incidence, Arab patients underwent surgery more often, suggesting delayed hospital admission of Arab as opposed to Jewish patients.

Abstract
OBJECTIVES These guidelines update and extend evidence-based indications for the management of children with acute gastroenteritis in Europe. METHODS The guideline development group formulated questions, identified data, and formulated recommendations. The latter were graded with the Muir Gray system and, in parallel, with the Grading of Recommendations, Assessment, Development and Evaluations system. RESULTS Gastroenteritis severity is linked to etiology, and rotavirus is the most severe infectious agent and is frequently associated with dehydration. Dehydration reflects severity and should be monitored by established score systems. Investigations are generally not needed. Oral rehydration with hypoosmolar solution is the major treatment and should start as soon as possible. Breast-feeding should not be interrupted. Regular feeding should continue with no dietary changes including milk. Data suggest that in the hospital setting, in non-breast-fed infants and young children, lactose-free feeds can be considered in the management of gastroenteritis. Active therapy may reduce the duration and severity of diarrhea. Effective interventions include administration of specific probiotics such as Lactobacillus GG or Saccharomyces boulardii, diosmectite or racecadotril. Anti-infectious drugs should be given in exceptional cases. Ondansetron is effective against vomiting, but its routine use requires safety clearance given the warning about severe cardiac effects. Hospitalization should generally be reserved for children requiring enteral/parenteral rehydration; most cases may be managed in an outpatients setting. Enteral rehydration is superior to intravenous rehydration. Ultrarapid schemes of intravenous rehydration are not superior to standard schemes and may be associated with higher readmission rates. CONCLUSIONS Acute gastroenteritis is best managed using a few simple, well-defined medical interventions.

Abstract
BACKGROUND AND OBJECTIVES To evaluate the burden of Rotavirus gastroenteritis (GE) among pediatric hospital admissions. DESIGN AND SETTINGS This is a retrospective observational study, in which all pediatric cases admitted to one of the biggest tertiary hospitals in Jeddah, with the diagnosis of GE, in the year 2010, were enrolled. PATIENTS AND METHODS This is a retrospective observational study in which all pediatric cases admitted with the diagnosis of GE in the year 2010 were enrolled. Clinical data and laboratory findings were compared between Rota positive and Rota negative cases. The data was statistically analyzed. RESULTS GE cases represented 8.8% of all pediatric hospital admissions in 2010. Almost 43% (42.9%) of these cases proved to have Rotavirus GE. Rotavirus infection alone, adenovirus infection alone, combined Rotavirus and adenovirus infection, and other causes of GE were present in 101 (33.6%), 21 (7%), 28 (9.3%), and 151 (50.2%) patients respectively. Coinfection with adenovirus was higher in Rota-positive GE (RPG; P=.039). Vaccination against Rotavirus was protective against Rotavirus GE (P=.042). CONCLUSIONS Rotavirus infection is the most important causative organism of GE in our community that accounted for 42.9% of children hospitalized for GE in our study, either alone or with other infections. Among our patients, vaccination against Rotavirus appeared to be protective against Rotavirus GE. In view of the high disease prevalence among children, locally and worldwide, we recommend routine Rotavirus vaccination as the most effective available means of control despite improvement in sanitation and hygiene.

Abstract
BACKGROUND A substantial number of surveillance studies have documented rotavirus prevalence among children admitted for dehydrating diarrhea. We sought to establish global seasonal patterns of rotavirus disease before the introduction of widespread vaccination. METHODS We reviewed studies of rotavirus detection in children with diarrhea published since 1995. We assessed potential relationships between seasonal prevalence and locality by plotting the average monthly proportion of diarrhea cases positive for rotavirus according to geography, country development and latitude. We used linear regression to identify variables that were potentially associated with the seasonal intensity of rotavirus. RESULTS Among a total of 99 studies representing all 6 geographic regions of the world, patterns of year-round disease were more evident in low- and low-middle income countries compared with upper-middle and high-income countries where disease was more likely to be seasonal. The level of country development was a stronger predictor of strength of seasonality (P = 0.001) than geographic location or climate. However, the observation of distinctly different seasonal patterns of rotavirus disease in some countries with similar geographic location, climate and level of development indicate that a single unifying explanation for variation in seasonality of rotavirus disease is unlikely. CONCLUSION While no unifying explanation emerged for varying rotavirus seasonality globally, the country income level was somewhat more predictive of the likelihood of having seasonal disease than other factors. Future evaluation of the effect of rotavirus vaccination on seasonal patterns of disease in different settings may help understand factors that drive the global seasonality of rotavirus disease.

Abstract
Rotavirus A causes severe diarrhoea in infants and young children worldwide. Many unusual combinations of G and P genotypes have been observed in rotaviruses circulating in developing countries. Mixed infection of a single individual with more than one strain is a mechanism by which genetic reassortants are formed with unusual G and P combinations. However, few studies have provided direct evidence for the formation of such unusual strains as a result of co-infection of co-circulating strains. Here, we used full-genome sequencing to re-analyze a G3P[4] strain (107E1B) and a G2P[4] strain (116E3D) detected in India in 1993 and showed that 107E1B had virtually an identical nucleotide sequence with 116E3D, except the VP7 gene. Phylogenetic analysis revealed that the 107E1B VP7 gene was of typical human rotavirus origin, with a 99.3% nucleotide sequence identity with another Indian G3 VP7 gene. Thus, this study provided robust evidence for the formation of the G3P[4] strain through genetic reassortment in which a G2P[4] strain with a typical DS-1 genogroup background acquired the VP7 gene from a co-circulating G3 human rotavirus strain. This study established a basis on which to facilitate full genome sequence analysis of an increasing number of G3P[4] strains in China and elsewhere in the world.

Abstract
The genome of rotaviruses consists of 11 segments of double-stranded RNA, and each genome segment has multiple genotypes. Thus, the genotype constellation of an isolate is often indicative of its host species. Albeit rarely, interspecies transmission occurs either by virions with nonreassorted or reassorted genomic segments. A rotavirus with the G6P[1] genotype, Ro8059, was isolated from the stool of a 1-year-old child during routine characterization of diarrheal specimens from a sentinel clinic in Israel in 1995. Since genotype G6P[1] is generally associated with bovine rotaviruses, and the child developed diarrhea within days of his first contact with calves at an urban farm, the aim of this study was to characterize the whole genomic constellation of Ro8059 and four G6P[1] bovine strains, BRV101, BRV105, BRV106, and CR231/39, by RNA-RNA hybridization and full genome sequencing to determine whether some or all of the segments were of bovine origin. The genome constellations of all four bovine G6P[1] strains were G6-P[1]-I2-R2-C2-M2-A3-N2-T6-E2-H3 for VP7-VP4-VP6-VP1-VP2-VP3-NSP1-NSP2-NSP3-NSP4-NSP5, respectively. Ro8059 shared the same genotype constellation with these bovine strains, with high nucleotide sequence identities (95.84 to 100%) for each of the 11 segments indicating that Ro8059 represented a direct interspecies whole-genome transmission of a nonreassorted rotavirus from a calf to a human infant. We conclude that this was the earliest example with a complete epidemiological link in which an entirely bovine rotavirus directly infected a human child and caused a symptomatic diarrheal illness. Thus, not all bovine rotaviruses are always naturally attenuated to the human host.

Diarrhea causes 15% of these deaths, and 40% of pediatric diarrhea-related hospitalizations are caused by rotavirus illness (RI). Rotavirus vaccination (RV), subsidized by international donors, is expected to reduce morbidity, mortality, and economic burden to the Bolivian state. Estimates of illness and economic burden of RI and their reduction by RV are essential to the Bolivian state's policies on RV program financing. The goal of this report is to estimate the economic burden of RI and the cost-effectiveness of the RV program. METHODS To assess treatment costs incurred by the healthcare system, we abstracted medical records from 287 inpatients and 6751 outpatients with acute diarrhea between 2005 and 2006 at 5 sentinel hospitals in 4 geographic regions. RI prevalence rates were estimated from 4 years of national hospital surveillance. We used a decision-analytic model to assess the potential cost-effectiveness of universal RV in Bolivia. RESULTS Our model estimates that, in a 5-year birth cohort, Bolivia will incur over US$3 million in direct medical costs due to RI. RV reduces, by at least 60%, outpatient visits, hospitalizations, deaths, and total direct medical costs associated with rotavirus diarrhea. Further, RV was cost-savings below a price of US$3.81 per dose and cost-effective below a price of US$194.10 per dose. Diarrheal mortality and hospitalization inputs were the most important drivers of rotavirus vaccine cost-effectiveness. DISCUSSION Our data will guide Bolivia's funding allocation for RV as international subsidies change.

Abstract
Genotyping circulating rotaviruses before and after introduction of rotavirus vaccine is useful for evaluating vaccine-associated changes in genotype distribution. We determined frequency of rotavirus genotypes among 61 rotavirus-positive children hospitalized in Israel during the 2005-06 rotavirus season. Accurate molecular epidemiologic data were recovered from affinity-concentrated rotavirus immobilized in rotavirus-positive bands from air-dried, diagnostic rotavirus rapid test strips (dipstick) stored at room temperature from 1 week to 5 years. G genotypes were identical for 21 paired dipsticks and suspensions, whereas dipsticks or suspensions detected an additional G genotype in 2 samples. RNA sequences from 7 pairs were identical. Phylogenetic analysis suggested previously unreported G2 sublineages and G9 lineages. The ease with which dipsticks can be stored at local facilities and transported to central reference laboratories can reverse increasing difficulties in obtaining geographically representative stool samples and expand surveillance to regions lacking adequate laboratory facilities.

Abstract
Background Rotavirus gastroenteritis (RVGE) is the most common cause of severe childhood diarrhea worldwide. Objectives were to estimate the burden of RVGE among children less than five years old in the Middle East (Bahrain, Iran, Iraq, Israel, Jordan, Kuwait, Oman, Qatar, Saudi Arabia, Syria, UAE, Yemen), North Africa (Algeria, Egypt, Libya, Morocco, Tunisia) and Turkey. Methods A comprehensive literature search was conducted in major databases on the epidemiology and burden of rotavirus among children less than five years old between 1999 and 2009. Data from each country was extracted and compared. Results The search identified 43 studies. RVGE was identified in 16-61% of all cases of acute gastroenteritis, with a peak in the winter. RVGE-related hospitalization rates ranged from 14% to 45%, compared to 14%-28% for non-RVGE. Annually, RVGE caused up to 112 fatalities per 100,000 in certain countries in the region. Hospitalization costs ranged from $1.8 to $4.6 million annually, depending on the country. The most recent literature available showed that G1P[8] was the most prevalent genotype combination in 8 countries (range 23%-56%). G2P[4] was most prevalent in 4 countries (26%-48%). G9P[8] and G4P[8] were also frequently detected. Conclusions RVGE is a common disease associated with significant morbidity, mortality, and economic burden. Given the variety and diverse rotavirus types in the region, use of a vaccine with broad and consistent serotype coverage would be important to help decrease the burden of RVGE in the Middle East and North Africa.

Abstract
Rotavirus is the most important etiological agent in children with acute gastroenteritis (AGE). The recent implementation of a rotavirus vaccine in Korea requires the monitoring of prevailing rotavirus strains in order to control the infection. One hundred thirty-nine rotavirus strains were detected in children hospitalized with AGE in Seoul, Korea from 2007 to 2009. The most frequent combination of genotypes was G9P[8] (32.1%), followed by G1P[8] (20.7%) and G3P[8] (11.7%). Mixed G-types were detected in 14 samples (10.0%), and mixed P-types were found in six samples (4.3%). G9 genotypes were predominant from 2007 to 2008, whereas G1 and G3 genotypes were predominant from 2008 to 2009. G1 strains clustered mostly in the Id lineage, and some clustered in the Ic, IId, and Ia lineages. G2 strains clustered in the IV and V lineages. G3 and G9 strains clustered in the IIId and Id lineages, respectively. This study shows a rapid change of the prevalent genotype from G9 to G1 and G3 genotypes, suggesting that continuous surveillance of rotavirus strains is important for rotavirus vaccination.
