Abstract Human astroviruses are a leading cause of gastrointestinal disease. Since their discovery in 1975 8 closely related serotypes have been described in humans and more recently two new astrovirus species astrovirus MLB1 and astrovirus VA1 were identified in diarrhea patients. In this study we used consensus astrovirus primers targeting the RNA polymerase to define the diversity of astroviruses present in pediatric patients with diarrhea on two continents. From 416 stool specimens comprising two different cohorts from Vellore India 35 samples were
