Fulminant Myocardial Involvement in Neonatal Echovirus-induced Sepsis. Two Autopsy Cases.

Group-B Enteroviruses, such as Echoviruses, are a common cause of infections in neonates but fatal myocarditis during Echovirus-induced sepsis have been rarely reported. We report on 2 cases of neonatal Echovirus-related sepsis with myocarditis. Fatal cardiorespiratory failure occurred in both cases. Autopsies and thorough histologic and microbiologic investigations evidenced Echoviruses 5- and 11-induced myocarditis as the cause of death.
