The rotavirus causing diarrhoea is an important contributing factor for malnutrition, which in turn predisposes the child to further diarrhoea, thereby initiating a vicious cycle. Hence based on this background, we conducted a study with the objective to know the proportion of rotavirus diarrhoea in children presenting with acute diarrhoea, and to study its clinical profile. The enrolled study Childrens were supervised for number of loose stools, consistency of stool and time since last loose stool every six hours in a day. The samples were analysed in Microbiology department in vaccine carrier; rotavirus detection was done by ELISA using Rota IDEIA Kit (DAKO, Germany). We conclude that rotavirus is responsible for about one-fourth of childhood diarrhoea under age of four years, and is associated with significant risk of dehydration and prolonged diarrhoea.
