Norovirus Gastroenteritis in a Birth Cohort in Southern India (Volume 11, Number 6)

Background Noroviruses are an important cause of gastroenteritis but little is known about disease and re-infection rates in community settings in Asia. Methods Disease, re-infection rates, strain prevalence and genetic susceptibility to noroviruses were investigated in a birth cohort of 373 Indian children followed up for three years. Stool samples from 1856 diarrheal episodes and 147 vomiting only episodes were screened for norovirus by RT-PCR. Norovirus positivity was correlated with clinical data, secretor status and ABO blood group.
