Between June 1979 and July 1980, faecal specimens were collected from 100 children in Efate, Vanuatu, and examined for the presence of virus-like particles by direct negative staining electron microscopy. Of the children, 40 were hospital patients 22 of whom had gastroenteritis and 18 had other illnesses. ⋯ Coronavirus-like particles were the most common agents encountered and were detected in approximately 20% of all three groups of children. Particles with the morphological features of calicivirus, astrovirus, adenovirus and parvovirus were also detected.
