Rota virus is the commonest agent for infectious diarrhoea in childhood. Whether an acute diarrhoea episode due to Rota virus constitutes a risk factor for persistence of diarrhoeal episode has not been well evaluated. This study aimed at evaluating the role of antecedent Rota virus infection in the causation of persistent diarrhoea. One hundred twenty children with acute watery diarrhoea were investigated for evidence of recent Rota virus infection and were followed up for 2 weeks to determine the proportion developing persistent diarrhoea. Rota virus antigen in stool and IgM class antibodies in serum were detected in 33 (27.5%) of the cases, only 2 (6.06%) of whom developed persistent diarrhoea. On the other hand 11.3% children without evidence for antecedent Rota virus infection developed persistent diarrhoea. The prevalence of Rota virus antigen in stools of children who developed persistent diarrhoea was 16.7%. In another group of 25 children with persistent diarrhoea definite evidence for a Rota virus infection was detected in only 2 (8%) cases. It was therefore concluded that antecedent Rota virus infection does not increase the risk for abnormal prolongation of an episode of acute diarrhoea.
