| Abstract: | An outbreak of Japanese encephalitis (JE) was reported from Rourkela city for the first time in September-November 1989. 41 cases and 15 deaths occurred with a case fatality rate of 36.6 per cent. Most of the cases (66 per cent) were in the age group of 5-19 years. There was no case under 5 years. Female-male ratio of cases was 1:1.7. Serological examination of convalescent cases showed JE specific IgM indicating strong evidence of recent JE infection. Large number of pigs were seen in the affected areas. |
