2507. Active Norovirus Surveillance in Children Under 5 Years With Diarrhea Following Rotavirus Vaccine Introduction in Argentina

摘要

BackgroundAcute diarrhea is one of the main causes of infant mortality. Argentina introduced massive rotavirus vaccination in 2015. This introduction in several countries, has changed the distribution of enteropathogens and has been described a decrease in the rotavirus prevalence at the expense of an increase in norovirus (NoV) activity. NoV is reported to be emerging as one of the main agents producing acute diarrhea in the community. In Argentina, there are few experiences estimating its prevalence in cases of acute diarrhea in children. The aim of this study was to analyze the role of NoV in outpatient children <5 years of age with acute diarrhea and their epidemiological pattern.
