From July 2007-June 2015, 61% of rotavirus-positive, vaccine-eligible children were unvaccinated for rotavirus. Of these, 67% of children had received DTaP within the recommended age for rotavirus vaccine initiation. Improving linkage between rotavirus and DTaP administration may impact the residual burden of U.S. rotavirus disease.

BACKGROUND: Rotavirus (RV) is a major agent of gastroenteritis and an important cause of child death worldwide. Immunization (RVI) has been available since 2006, and the Federation of International Societies of Gastroenterology Hepatology and Nutrition (FISPGHAN) identified RVI as a top priority for the control of diarrheal illness. A FISPGHAN working group on acute diarrhea aimed at estimating the current RVI coverage worldwide and identifying barriers to implementation at local level...

In the Kingdom of Saudi Arabia (KSA), rotavirus universal mass vaccination has been introduced in 2013, however, there is limited information available on the economic benefit and the epidemiological impact of the programme to date. We used a Markov cohort model to evaluate and compare the economic value of rotavirus vaccination with no vaccination in a birth cohort of 562,428 infants. This lifetime analysis considered the societal perspective. Model input was obtained through consensus of local experts after two rounds of evaluation of the proposed estimates...

Rotaviruses (RVs) are important enteric pathogens of newborn humans and animals, causing diarrhea and in rare cases death, especially in very young individuals. Rotavirus vaccines presently used are modified live vaccines that lack complete biological safety. Previous work from our laboratory suggested that vaccines based on in situ produced, non-infectious rotavirus-like particles (RVLPs) are efficient while being entirely safe. However, using either vaccine, active mucosal immunization cannot induce protective immunity in newborns due to their immature immune system...

The strategies for developing rotavirus (RV) vaccines have always been controversial. At present, both the monovalent RV vaccine and the multivalent RV vaccine have displayed excellent safety and efficacy against RV infection and shown cross-reactive immunity, which laid the question whether the multivalent RV vaccine could be replaced by the monovalent RV vaccine. In this study, we focused on comparing the immunogenicity (serum neutralization activity and protection against homotypic and heterotypic RVs' challenge) of individual standard RV strains (monovalent RV immunogens) and different combinations of them (multivalent RV immunogens)...

BACKGROUND: The Institute of Medicine, in a 2013 report, recommended that the Vaccine Safety Datalink (VSD) expand collaborations to include more diversity in the study population. Kaiser Permanente Colorado (KPCO), an established VSD site, partnered with Denver Health (DH), an integrated safety net healthcare system, to demonstrate the feasibility of integrating DH data within the VSD. Prior to incorporating the data, we examined the identification of specific vaccine associated adverse events (VAEs) in these two distinct healthcare systems...

Rio de Janeiro's inner and coastal waters are heavily impacted by human sewage pollution for decades. Enteric viruses, including human adenoviruses (HAdV), human enterovirus (EV), group A rotavirus (RV) and hepatitis A virus (HAV) are more likely to be found in contaminated surface waters. The present work aimed to assess the frequency and loads of EV, HAdV-C and -F species, RV and HAV in sand and water samples from venues used during the 2016 Summer Olympics and by tourists attending the event. Sixteen monthly collections were carried out from March 2015 to July 2016 in 12 different sites from Rio de Janeiro, Brazil...

Gastroenteritis is a common disease in children, characterized by diarrhea, vomiting, abdominal pain, and fever. Sapovirus (SaV) is a causative agent of acute gastroenteritis although it causes milder illness than rotavirus and norovirus. There is high variability in analytical performance of quantitative PCR-based assays amongst clinical laboratories. This study develops a RT real-time PCR method to detect SaV in fecal specimens collected from under-five-year-old children with acute gastroenteritis. 15 out of 137 (10...

An 11-d-old Holstein bull calf was presented to the Veterinary Medical Teaching Hospital at the University of Wisconsin-Madison because of a 4-d history of diarrhea and persistent low-grade fever. Initial diagnosis was enteritis caused by Cryptosporidium and rotavirus. During hospitalization, the calf became stuporous and was only responsive to noxious stimuli, with hypotonia of all 4 limbs, tail, head, and neck. A cerebrospinal fluid analysis revealed xanthochromia, with marked lymphocytic pleocytosis, which was suggestive of viral meningitis and/or encephalitis...

: Pediatric urolithiasis associated with acute gastroenteritis (AGE) has not been systematically investigated, including its prevalence, risk estimate, and outcome. Using a national inpatient database in Japan, we searched for children (≤59 months old) who were hospitalized for AGE and those complicated by urolithiasis over a 24-month period. We found 23 cases of urolithiasis among 62,800 children who were hospitalized for AGE (3.7 cases/10,000 AGE admissions). AGE was associated with an increased risk of urolithiasis (odds ratio 2...

Monitoring effluents from wastewater treatment plants is important to preventing both environmental contamination and the spread of disease. We evaluated the occurrence of human enteric bacteria (faecal coliforms and Escherichia coli) and viruses (rotavirus and enterovirus) in the final effluents of five wastewater treatment plants (WWTPs) in the Eastern Cape of South Africa. Human viruses were recovered from the effluent samples with the adsorption-elution method and detected with singleplex real-time RT-PCR assays...

Rotavirus causes significant morbidity and mortality among children worldwide. Stool samples from a previous hospital-based surveillance study to detect diarrhea etiology at the National Pediatric Hospital in Phnom Penh, Cambodia, by Meng and others in 2011 were tested for rotavirus by real-time reverse transcription polymerase chain reaction (PCR) targeting vp6 gene and characterized for G- and P-genotypes of positive samples based on vp7 and vp4 genes, respectively. Rotavirus was detected in 159/531 (30%) of children with diarrhea and none was detected in 287 nondiarrhea controls...

Human milk contains bioactive compounds that confer a protective role against gastrointestinal infections. In order to find supplements for an infant formula able to mimic these benefits of breast-feeding, two different concepts were tested. The products consisted of the following: (1) a Bifidobacterium breve- and Streptococcus thermophilus-fermented formula and (2) a combination of short-chain galacto-oligosaccharides/long-chain fructo-oligosaccharides with pectin-derived acidic oligosaccharides. A rotavirus infection suckling rat model was used to evaluate improvements in the infectious process and in the immune response of supplemented animals...
