Noncultivable viruses and neonatal diarrhea: fifteen-month survey in a newborn special care nursery.

ABSTRACT

During a 15-month period of surveillance, diarrhea developed in 257 of 913 babies (28%) admitted within 2 hours of birth to a special care nursery in Melbourne, Australia. Diarrhea was seasonal, affecting a maximum of 43% of babies admitted during one winter month (July) and a minimum of 13% of babies admitted during one summer month (December). Diarrhea was no more frequent nor more severe in babies of very low birth weight or of very early gestational age. Two noncultivable viruses were located by electron microscopy in feces from babies with or without diarrhea. Excretion of a reovirus-like particle (rotavirus, duovirus, human reovirus-like agent, infantile gastroenteritis virus) was temporally related to diarrheal symptoms. Asymptomatic infection with this virus also occurred. A 28-nm virus-like particle was excreted by some babies, but it could not be implicated on epidemiological grounds in the etiology of the diarrhea. Rotavirus infection may be an important cause of endemic diarrhea in nurseries for the newborn. Infection may be difficult to control or eradicate, since it is often asymptomatic and may be influenced by infection in the community at large.
