Abstract
BACKGROUND: The sudden death of 10 children in a tribal village of Kandhamal district, Odisha in eastern India led to this investigation. METHODS: We conducted a door-to-door survey to identify cases. Antibodies for Chandipura, Japanese encephalitis, dengue, chikungunya and West Nile viruses were tested by ELISA in probable cases. Chandipura virus RNA was tested from both human blood samples and sand flies by reverse transcriptase polymerase chain reaction. We conducted vector surveys in domestic and peridomestic areas, and collected sand flies. RESULTS: Entomological investigations revealed the presence of Phlebotomus argentipes and Sergentomiya sp. Thirty-five patients presented with fever, 12 of them had altered sensorium including 4 who had convulsions. The blood samples of 21 patients were tested; four samples revealed Chandipura virusspecific IgM antibody. CONCLUSION: Chandipura virus infection causing encephalitis affected this tribal population in eastern India at 1212 m above sea level. Copyright 2015, NMJI.
