The JE virus, carried primarily by waterfowl and amplified in pigs, is transmitted to humans via infected Culex mosquitoes. Although the virus can cause febrile and neurological illnesses, it does not spread through human-to-human contact.

Addressing concerns, officials assured the public that no outbreak has occurred in Delhi, and most reported cases are from neighbouring states.

"The occasional isolated cases have been reported from tertiary hospitals like AIIMS, RMLH, and SJH. All public health measures, including those outlined by the National Centre for Vector-Borne Diseases Control (NCVBDC), are in place to manage the situation," officials noted.

Nationwide, data from the Integrated Disease Surveillance Programme (IDSP) reveals 1,548 JE cases in 2024, with Assam accounting for 925 cases. The disease is concentrated in 24 states and union territories.

Since 2013, the Universal Immunization Programme has included two doses of the JE vaccine for children, with adult vaccination introduced in high-burden states to curb the disease. Despite this, JE remains a concern in specific regions due to its potential for severe neurological complications and fatalities.

A person with the disease Japanese Encephalitis will typically have either no symptoms at all or only minor ones. Fever and headache are moderate symptoms, while nausea, vomiting, stiff neck, speech impediment, and spastic paralysis are severe ones.

For prevention, people should wear long-sleeved clothing, use mosquito nets, insecticides, and repellents, clean standing water and drains, and maintain a clean environment around their homes, news agency ANI reported.

It is advised to get immunised in order to prevent contracting JE. In areas where the Japanese encephalitis virus (JEV) is prevalent, a vaccine against it has been included in the Indian Universal Immunisation Programme (UIP).
