Abstract
Noroviruses are a leading cause of diarrhea in children aged <5 years worldwide. We genotyped 88 viruses collected by active surveillance in a birth cohort of children <2 years of age in Dhaka, Bangladesh, during 2010-2013. Twenty-five of 31 (81%) established GI and GII genotypes were detected, with GII.4 as the predominant genotype (20%). Our results show that children in Bangladesh are infected with a great diversity of norovirus strains. Reinfections are common, but not with closely related genotypes. Birth cohort studies are critical to understand cross-protective immunity and advance the development of pediatric norovirus vaccines.
