Abstract
BACKGROUND Multiplex-PCR is a valuable tool for diagnosing viral acute gastroenteritis (AGE), enabling the detection of multiple pathogens. However, distinguishing between active disease and shedding poses challenges. This study aimed to evaluate viral AGE epidemiology and compare clinical characteristics among the five most common viruses. METHODS Rotavirus vaccine was introduced in 2010, with 70% coverage achieved in southern Israel in two years. All rectal swabs for multiplex-PCR targeting rotavirus, norovirus, adenovirus, astrovirus and sapovirus from hospitalized diarrheic children <5 years were included, from December 2017 through March 2022. Detection of the same virus within two months was considered a single episode. Clinical analysis included episodes with single-virus detection and negative bacterial PCR. RESULTS Among 5,879 rectal swabs, 2,662 (45.3%) tested positive for at least one virus, with 245 (9.2%) showing multiple virus detection. Rotavirus was the most prevalent. While rotavirus exhibited typical winter-spring seasonality in 2018-19, an unusual off-season surge was observed during the second year of the COVID-19 pandemic. Among negative bacterial PCR episodes, 34.6% had mucus stool, 5.9% had bloody stool, and 29.3% received antibiotics. Astrovirus or sapovirus infections were associated with higher rates of hospital-acquired AGE and immunodeficiency (P<0.05), whereas rotavirus infections had higher rates of dehydration severity and acute kidney injury (P<0.05). DISCUSSION Enteric viruses were detected in 45.3% of rectal swabs from hospitalized children with diarrhea. Despite vaccination efforts, rotavirus remained prevalent and caused more severe disease. Continuous surveillance using multiplex-PCR is crucial for accurate management and future prevention strategies for viral AGE.

Abstract
BACKGROUND Rotavirus infection remains an important cause of morbidity and mortality in children. The introduction of vaccination programs in more than 100 countries has contributed to a decrease in hospitalizations and mortality. This study investigates the epidemiological impact of the rotavirus vaccine ROTAVAC® in the Palestinian Territories, the first country to switch from ROTARIX® to this new vaccine. METHODS Clinical surveillance data was collected fromchildren younger than 5attendingoutpatient clinics throughout Gaza withdiarrhea between 2015 and 2020. The incidence of all-cause diarrhea was assessed using an interrupted time-series approach. Rotavirus prevalence was determined at the Caritas Baby Hospital in the West Bank usingELISA on stool specimen of children younger than 5with diarrhea. Genotyping was performed on 325 randomly selected rotavirus-positive samples from January 2015 through December 2020 using multiplex PCR analysis. RESULTS Average monthly diarrhea casesdropped by 16.7% annually fromintroduction of rotavirus vaccination in May 2016 to the beginning of the SARS-CoV-2 epidemic in March 2020 for a total of 53%. Case count declines were maintained afterthe switchto ROTAVAC® in October 2018. Rotavirus positivity in stool samples declined by 67.1% over the same period without change followingthe switch to ROTAVAC®. The distribution of predominant genotypes in rotavirus-positive stool samples changed from a pre-vaccination G1P [8] to G9P[8] and G12P[8] during the ROTARIX® period and G2P[4] after the introduction of ROTAVAC®. CONCLUSION ROTAVAC® has shown epidemiological impact on par with ROTARIX® after its introduction to the national immunization schedule in the Palestinian Territories. A molecular genotype shift from a pre-vaccination predominance of G1P[8] to a current predominance of G2P[4] requires more long-term surveillance.

Abstract
Group A rotaviruses remain the leading cause of diarrhoea in children aged <5 years. Mozambique introduced rotavirus vaccine (Rotarix®) in September 2015. We report rotavirus genotypes circulating among symptomatic and asymptomatic children in Manhiça District, Mozambique, pre- and post-vaccine introduction. Stool was collected from enrolled children and screened for rotavirus by enzyme-immuno-sorbent assay. Positive specimens were genotyped for VP7 (G genotypes) and VP4 (P genotypes) by the conventional reverse transcriptase polymerase chain reaction. The combination G12P[8] was more frequently observed in pre-vaccine than in post-vaccine introduction, in moderate to severe diarrhoea (34%, 61/177 vs. 0, p < 0.0001) and controls (23%, 26/113 vs. 0, p = 0.0013) and mixed genotypes (36%, 24/67 vs. 7% 4/58, p = 0.0003) in less severe diarrhoea. We observed changes in post-vaccine compared to pre-vaccine introduction, where G3P[4] and G3P[8] were prevalent in moderate to severe diarrhoea (10%, 5/49 vs. 0, p = 0.0002; and 14%, 7/49 vs. 1%, 1/177, p < 0.0001; respectively), and in less severe diarrhoea (21%, 12/58 vs. 0, p = 0.003; and 24%, 14/58 vs. 0, p < 0.0001; respectively). Our surveillance demonstrated the circulation of similar genotypes contemporaneously among cases and controls, as well as switching from pre- to post-vaccine introduction. Continuous surveillance is needed to evaluate the dynamics of the changes in genotypes following vaccine introduction.

Abstract
The surveillance of enteric pathogens is critical in assessing the burden of diarrhoeal disease and informing vaccine programs. Surveillance supported by the World Health Organization in Fiji, Vietnam, the Lao People’s Democratic Republic, and the Philippines previously focussed on rotavirus. There is potential to expand surveillance to encompass a variety of enteric pathogens to inform vaccine development for norovirus, enterotoxigenic Escherichia coli and Shigella.
