ABSTRACT
Introduction This study aimed to monitor the seasonality of rotavirus infection, and gain insight into the variability of Brazilian strains. Methods A total of 28 stool samples were analyzed from 698 revised cases of gastroenteritis during a norovirus outbreak in the summer of 2010 in Guarujá, Brazil. Diagnosis was performed using enzyme-linked immunosorbent assay (ELISA), reverse transcription polymerase chain reaction (RT-PCR), and sequencing. Results Rotavirus infection was detected in 17.9% (5/28) of samples; 4 samples were G2P[4] genotype, and one G2P[4]+P[6] genotype. G2 and P[4] sequences showed a genetic relationship to strains from India and Russia, respectively. Conclusions The seasonal pattern of rotavirus may be a consequence of human activity apart from climate factors. .
