This survey is concerned with isolations of enteroviruses from sewage and stools of children admitted to pediatric wards of the Clermont-Ferrand hospital during 4 years (from january 1, 1980, to december 31, 1983). Some epidemics of different serotypes (Coxsackies B1, B4, B5, Echovirus 33) occurred, mainly between june and october. In some instances, virus isolation in sewage occurred a few weeks before epidemic of the same virus, giving some predictive value to pediatric pathology. This survey allowed us to adapt immunologic diagnosis of enteroviruses in children and limit the use of expensive reagents.
