J Vector Dis
-
Japanese encephalitis virus (JEV), a mosquito borne pathogen, is one of the major causes of viral encephalitis in eastern Uttar Pradesh, India. The objective of this work was to evaluate the entomological based virological surveillance of Japanese encephalitis (JE) in the highly endemic area of eastern Uttar Pradesh. ⋯ The findings showed the rapid dissemination of JEV within a population, facilitated by different species of Culex in the region. As JE is a vaccine-preventable disease, an immunization programme, an effective vector control strategy and application of standard hygiene practices in these endemic areas could result in a considerable reduction in morbidity and mortality due to JE.
