Two concurrent epidemics of enteroviral meningitis in an obstetric neonatal unit.

ABSTRACT

A small epidemic of viral infection occurred in a neonatal unit. It involved 11 infants, all of whom recovered. Echovirus 11 was the cause of illness in six infants, coxsackie B3 in four, and one infant had a biphasic illness, due first to echo 11, then to coxsackie B3. The epidemic coincided with a major outbreak of echovirus 11 and a smaller outbreak of coxsackie B3 in the community. Several staff became ill. Five infants were considered to have been infected by perinatal materno-infant spread, others by cross-infection. The epidemic ended when the nursery was closed.
