ABSTRACT

Japanese encephalitis (JE) is a re-emerging mosquito borne zoonotic flaviviral disease and is the most
common cause of encephalitis in children of Asia leading to several deaths every year in our country. The present investigation was undertaken to assess the sero-positivity of Japanese encephalitis virus in swine population using virus neutralization test. A total of 181 swine serum samples were collected from various regions of Uttar Pradesh, Chandigarh, Kerala and Goa. The study revealed overall sero-positivity of 59.11%. The sero-positivity in different regions was found to be 78.94% for Goa, 60.97% for Kerala, 56.14% for Uttar Pradesh and 43.47% for Chandigarh. The present study revealed the high sero-positivity of JEV in swine population of various Indian states and highlights the need for more extensive surveillance from different parts of country to confirm the exact status of JE for formulating the necessary preventive measures.
