Rising Concerns Over Encephalitis in India
India’s Encephalitis Burden Sparks Call for Dedicated National Programme: India is witnessing a renewed health challenge with encephalitis, an inflammation of the brain often caused by viral infections like the Japanese Encephalitis Virus (JEV). The World Health Organization (WHO) recently flagged it as a serious public health concern, pointing to under-reported cases and increasing outbreaks. In 2024, a particularly alarming surge in Acute Encephalitis Syndrome (AES) cases was noted, highlighting the disease’s severe impact on children in rural regions.
What Causes Encephalitis?
Encephalitis is often triggered by viruses, but bacteria or autoimmune responses can also cause it. In India, the Japanese Encephalitis Virus (JEV) is a major contributor. Transmitted via mosquitoes, JEV is especially active during the monsoon season in parts of Uttar Pradesh, Bihar, and Assam. In a disturbing turn in 2024, the Chandipura Virus (CHPV) caused an outbreak that affected 245 children, primarily under the age of 15, with symptoms like fever, seizures, and altered consciousness.
Reporting and Diagnosis Gaps
One of the most pressing problems is under-reporting. Health experts note that encephalitis is often tracked only during major outbreaks. There’s no centralised, year-round reporting system for the disease. The problem is further complicated by the lack of rapid diagnostic tools in remote and rural hospitals, where most AES cases occur. Without timely detection, treatment is delayed, increasing the risk of fatality or long-term neurological issues.
Training and Awareness Are Essential
Early symptoms of encephalitis can include light sensitivity, severe headaches, vomiting, and confusion. However, these are frequently missed by both caregivers and frontline healthcare workers. Experts say that training ASHA and primary care staff is crucial so they can detect red flags and act swiftly. Community awareness campaigns—especially in endemic districts—can also help reduce infection rates by educating families on mosquito control and hygiene practices.
India’s Patchy Prevention Efforts
Although vaccination programmes exist for JEV, they are not uniformly implemented across high-risk districts. Unlike diseases like TB, encephalitis lacks a dedicated national control programme. Preventive steps such as mosquito eradication, eliminating stagnant water, and seasonal alerts are carried out inconsistently. Experts believe that a more structured and dedicated approach would significantly lower the case count and improve outcomes.
Need for a National Encephalitis Programme
Public health specialists are now urging the government to establish a standalone encephalitis prevention programme. This would ensure better vaccine distribution, active surveillance, and accurate data collection. A focused initiative could also standardise diagnostic protocols and improve access to treatment in underserved areas. If implemented, such a programme could dramatically reduce both fatalities and long-term disabilities, especially among children in the poorest districts.
