Journal ArticleDOI

Rotavirus vaccine and health care utilization for diarrhea in U.S. children.

TL;DR: Since the introduction of rotavirus vaccine, diarrhea-associated health care utilization and medical expenditures for U.S. children have decreased substantially and direct benefits (in unvaccinated children) were seen in 2007-2008 but not in 2008-2009.
Journal ArticleDOI

An outbreak of viral gastroenteritis associated with consumption of sandwiches: implications for the control of transmission by food handlers.

TL;DR: Current recommendations to exclude food handlers from work for 48–72 h after recovery from illness may not always prevent transmission of Norwalk-like viruses because virus can be shed up to 10 days after illness or while exhibiting no symptoms.
Journal ArticleDOI

United States rotavirus strain surveillance from 2005 to 2008: genotype prevalence before and after vaccine introduction.

TL;DR: The increased overall prevalence of G3P [8] strains in 2007–2008, the first rotavirus season with reasonableRotavirus vaccine coverage, was consistent with Australian reports of G 3 dominance following RotaTeq introduction, and underscores the need for careful monitoring of strains to assess possible vaccine pressure-induced changes and vaccine effectiveness against various rotav virus genotypes.
Journal ArticleDOI

Uptake, impact, and effectiveness of rotavirus vaccination in the United States: review of the first 3 years of postlicensure data.

TL;DR: The implementation of routine childhood immunization againstRotavirus has rapidly and dramatically reduced the large health burden of rotavirus gastroenteritis in US children and continued monitoring of rotvirus diarrhea is needed to determine if immunity wanes as vaccinated children get older and to better quantify the indirect benefits of vaccination.
Journal ArticleDOI

Severe outcomes are associated with genogroup 2 genotype 4 norovirus outbreaks: a systematic literature review

TL;DR: It is suggested that hospitalizations and deaths were more likely in outbreaks associated with G II.4 viruses, independent of other factors, and underscores the importance of developing vaccines against GII.
