Vibrio cholerae O139 was recovered from 28 of 79 children with acute watery diarrhoea. Clinically, they presented with watery diarrhoea (100%), vomiting (79%), abdominal cramps (61%), anorexia (61%), dehydration (100%), and absence of fever. Both clinical and blood biochemical parameters of these cases were similar to the illness caused by the new strain in adults. Hypoglycaemia was seen in 40% of those screened.
