1540. Clinical severity across five viral diarrheal pathogens in infants and young children Global Enteric Multicenter Study (GEMS)

Abstract Background Viruses are a leading cause of pediatric diarrheal illness, resulting in over 200,000 childhood deaths annually worldwide. Rotavirus is the most common viral cause of moderate-to-severe diarrhea in low to middle-income countries, but adenovirus 40/41, norovirus, sapovirus, and astrovirus are increasingly recognized as important contributors to the global viral gastroenteritis burden. Comparisons of clinical severity between these five viruses among infants and young children are currently limited. Methods The objective of this analysis was to describe the clinical severity of rotavirus, adenovirus 40/41, norovirus, sapovirus, and astrovirus among children enrolled in the Global Enteric Multicenter Study (GEMS). Stool samples from children younger than 5 years of age with moderate-to-severe diarrhea at four sites in Africa and three in…
