Japanese Encephalitis (JE) Vaccine

Japanese Encephalitis (JE) is primarily endemic in certain regions of India, particularly in rural and agricultural areas where conditions favor the breeding of the Culex mosquitoes, which transmit the virus. The endemic areas in India for JE typically include:

• Uttar Pradesh: Terai Region of Uttar Pradesh has historically been a hotspot for JE.

• Bihar: Especially in areas with significant rice cultivation and pig farming.

• Assam and North Eastern States: These areas have reported a significant number of JE cases, given their ecological conditions conducive to mosquito breeding.

• West Bengal: Especially in the rural areas, JE cases have been frequently reported.

• Andhra Pradesh and Tamil Nadu: Parts of these states have also seen JE outbreaks.

• Karnataka: Certain districts in Karnataka have reported JE cases, particularly those with large water bodies and paddy fields.

• Maharashtra: JE cases have been reported in some districts, although not as prevalent as in the northern and northeastern states.

• Other States: JE has sporadically been reported in other states as well, but with lesser frequency and intensity compared to the states mentioned above.

It’s important to note that JE distribution and prevalence can change over time due to factors like environmental changes, urbanization, vaccination programs, and vector control measures. Therefore, it’s always advisable to consult with healthcare professionals or local health authorities for the most current information, especially when traveling to or residing in areas potentially at risk for JE.
