Enterovirus infections in neonates.

Enteroviruses, which include echoviruses, coxsackie A and B viruses, polioviruses and the 'numbered' enteroviruses, are among the most common viruses causing disease in humans. A large proportion of enteroviral infections occur in neonates and infants. There is a wide spectrum of clinical manifestations that can be caused by enterovirus infection with varying degrees of severity. In the neonatal age group, enteroviral infections are associated with significant morbidity and mortality, particularly when infection occurs antenatally. This review provides a detailed overview of the epidemiology and clinical features of enterovirus infections in the neonatal period. In addition, laboratory features and diagnostic investigations are discussed. A review of the currently available data for prophylactic and therapeutic interventions, including antiviral therapy, is also presented.
