In 2025, India has seen a significant outbreak of Japanese Encephalitis (JE), with 224 confirmed cases reported across 11 states. Assam tops the list, accounting for approximately half of the cases, highlighting the state’s endemic status and the urgent need for intensified disease control efforts.
JE, a mosquito-borne viral infection primarily transmitted by Culex mosquitoes, poses a serious public health challenge, especially among children under 15 and vulnerable rural populations. In Assam alone, 127 cases have been confirmed by mid-2025, with the virus spreading to 33 of the state’s 35 districts and causing 26 reported deaths so far. The disease is now present in multiple districts across other states including Uttar Pradesh, Bihar, Jharkhand, and Karnataka, among others.
Surveillance and response measures are being ramped up nationwide to curb the spread of JE. Vaccination campaigns targeting children aged 1-15 years are underway or planned in many affected regions, supported by the government’s expanded immunization programs. Moreover, health authorities are emphasizing vector control measures such as mosquito population management alongside community awareness drives to prevent new infections.
Given the potentially severe neurological impact and high fatality rate associated with JE, the Union Ministry of Health is coordinating with states for a multi-pronged strategy including improved case management facilities in district hospitals and rehabilitation centers for affected patients.
