Abstract
We report the molecular epidemiology of astrovirus infection in 335 infants with diarrhea in Wuhan City, China. Astrovirus RNA was detected in the stool specimens of 33 children (9.87%). Genotyping analysis indicated that 23 out of 24 astroviruses identified were classified as belonging to genotype 1, with highest identity (>98%) to a Mongolian strain.
