Viral Diarrhea	2008-08-26		.txt	text/plain	5682	282	39	Of the 'non-group A' rotaviruses, group B rotavirus has been identified in epidemic outbreaks of severe diarrhea in adults in China and in symptomatic infections in children. Between 20% and 50% of cases of gastroenteritis caused by rotavirus in hospitals are considered to be of nosocomial origin, and nosocomial viral enteric infections have been documented in up to 6% of children admitted for more than 72 hours in both developed and developing countries. Rotaviruses induce a clinical illness characterized by vomiting, diarrhea, abdominal discomfort, fever, and dehydration (or a combination of some of these symptoms) that occurs primarily in infants and young children and may lead to hospitalization for rehydration therapy. Studies in adult volunteers indicate that people with detectable levels of antibodies do not develop the illness, although epidemiological observations suggest that human astrovirus infections do not induce heterotypic immunity, as an episode of astrovirus diarrhea is not associated with a reduced incidence of a subsequent episode.	./cache/cord-274643-vjb2yt93.txt	./txt/cord-274643-vjb2yt93.txt
