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.

The reovirus-like agent, sometimes referred to as duovirus or rotavirus, was visualized by electron microscopy in stool extracts from Japanese infants and young children with acute epidemic gastroenteritis. The virus particles measured 70 nm in diameter and had double-shelled capsids. One hundred ten (89%) of 124 patients with the gastroenteritis had such virus particles in stools obtained during the acute phase.

In a study of patients admitted with a diarrhoeal illness to the Children's Hospital of the District of Columbia in the United States from January 1974 to June 1975, it was found that half of the patients studied by both virus shedding (by electron microscopy) and serological (complement-fixation) techniques demonstrated evidence of infection with the HRVL agent. The temporal distribution of infections with the HRVL agent followed a seasonal pattern with this agent being shed exclusively by patients admitted during the cooler months of the year.
