Rotavirus is a major cause of acute gastroenteritis in children under 5 years of age, with severe illness occurring in 30-40% of cases. In Italian region of Liguria, vaccination with a two-dose human attenuated vaccine was introduced in 2013. We conducted a retrospective study to assess the impact of rotavirus vaccine on hospitalizations for rotavirus-related gastroenteritis (RVGE) at the IRCCS Istituto Giannina Gaslini. Every hospitalization due to laboratory-confirmed RVGE and acute gastroenteritis of unknown origin (AGUO) in patients aged 0-14 years in the period 2008-2019 were anonymously extracted. Vaccine coverage were obtained from the regional vaccination registry. The results were divided in 2008-2012 (before RV vaccine) and 2013-2019 (after) periods. From 2008 to 2012, there was a continuous reduction of AGUO hospitalizations while RVGE increased. Since 2013, a reduction in hospitalization rate was observed for RVGE with a sharp decrease from 17.81 per 10.000 children in 2012 to 0.79 per 10,000 in 2019, parallel with the ascending values of RV vaccination coverage that increased from 36.3% in 2013 to 63.9% in 2019. A significant negative correlation was found between the proportions of vaccinated newborns and RVGE rates ( = .012). Intussusception-related hospitalization did not show substantial modifications. We confirm vaccination as a safe practice that has a significant impact in pediatric hospitalization rates.

Impact of water, sanitation, and hygiene indicators on enteric viral pathogens among under-5 children in low resource settings.

Poor water, sanitation, and hygiene (WASH) are the primary risks of exposure to enteric viral infection. Our study aimed to describe the role of WASH conditions and practices as risk factors for enteric viral infections in children under 5. Literature on the risk factors associated with all-cause diarrhea masks the taxa-specific drivers of diarrhea from specific pathogens, limiting the application of relevant control strategies.

This study investigated the survival of human rotavirus (HRV) on fresh beef, chicken, and lettuce stored at various temperatures, as well as the effect of UV-C exposure on HRV viability on these food surfaces. At 20 °C, the survival rate of three HRV strains (WA, 89-12C2, and DS-1) on beef, chicken, and lettuce decreased within 3 days, with the most significant reduction observed on beef. When stored at 4 °C, a significant reduction in HRV viability was observed by day 7, with the greatest decrease observed on beef, followed by chicken and lettuce.

Oral vaccines have several advantages compared with parenteral administration: they can be relatively cheap to produce in high quantities, easier to administer, and induce intestinal mucosal immunity that can protect against infection. These characteristics have led to successful use of oral vaccines against rotavirus, polio, and cholera. Unfortunately, oral vaccines for all three diseases have demonstrated lower performance in the highest-burden settings where they are most needed.

Rotavirus (RV) is a significant contributor to diarrhea in both young children and animals, especially in piglets, resulting in considerable economic impacts on the global pig industry. Isoleucine (Ile), a branched-chain amino acid, is crucial for regulating nutrient metabolism and has been found to help mitigate diarrhea. This study aimed to assess the impact of isoleucine supplementation in feed on colonic barrier function, colonic microbiota, and metabolism in RV-infected weanling piglets.

Background: SARS-CoV-2 infection is generally associated with less severe forms of disease in children, where most cases only require symptomatic treatment. However, there is a paucity of information regarding the impact and clinical course of COVID-19 in neonate patients. This study aimed to analyze the epidemiological and clinical aspects of COVID-19 in this particular age group who were patients treated in our department.
