Detection of rotavirus in children with acute gastroenteritis in Porto Velho, Rondonia, Brazil.
2014
Rotavirus group A (RVA) infection was ascertained in 591 fecal samples from children 0 to 6 years old with acute gastroenteritis. The vaccination status was also verified in all 591 subjects, with 302 (51.0 % ± 4.0 %) participants fully vaccinated against rotavirus. Forty-two of the vaccinated children (13.9 % ± 3.9 %) tested positive for RVA infection. Of the 289 unvaccinated children (49.0 % ± 4.0 %), 61 (21.1 % ± 4.7 %) had stools positive for RVA. This study suggests that the pro- portion of acute diarrhea cases caused by rotavirus was low and that the incidence of rotavirus diarrhea decreased over the study period in both vaccinated and unvaccinated children.
