The aetiological contribution of viral agents in the causation of acute diarrhoea was studied prospectively in 915 infants and young children aged 135 months. This was a hospital-based study, selection being carried out by proportionate random sampling; 587 matched controls were also investigated simultaneously. Methods of detection included direct electron microscopy, ELISA for rotaviruses and immune electron microscopy. Rotaviruses emerged as the single most important cause with highest prevalence in the 611-month age group. The contribution of other agents was negligible. Electron microscopy, though a catch-all technique, is not a cost-effective diagnostic method for developing countries.
