Clinical characteristics and molecular epidemiology of Enterovirus infection in infants <3 months in a referral paediatric hospital of Barcelona.

The most common EV types were Echovirus-5 and Echovirus-11. Some significant associations between types and epidemiologic and clinical findings were observed. What is Known-What is New • Enteroviruses cause a normally benign illness in young infants, except in some cases. • The molecular epidemiology of Enterovirus infection is not well known in European countries. • This study describes a large number of infants with Enterovirus infection and shows the seasonality of different types, and their associations with epidemiologic and clinical variables.
