Prevalence of rotavirus in acute diarrhea and its association with clinical signs and symptoms.

Rotaviruses are the main etiological agents of acute infectious diarrhea in children. Thus, the objective of this study is to contribute to the information about the rotavirus variants circulating in Brazil. A cross-sectional study was conducted on 124 fecal samples collected from children up to the age of 5 years, with acute gastroenteritis. Thirty-one samples were positive for rotavirus A. Regarding the G genotyping, 16 (80%) were classified as G1 and regarding P genotyping all strains were classified as P[8]. The determination of the prevalence of rotavirus infection and the characterization of the viral strains circulating are expected to contribute to the information we have about the molecular biology and epidemiology of disease.
