How UP won the battle against encephalitis

· OpIndia

For nearly four decades, eastern Uttar Pradesh lived under the constant shadow of Acute Encephalitis Syndrome (AES) and Japanese Encephalitis (JE). Every year, especially during the monsoon season, districts such as Gorakhpur, Kushinagar, Maharajganj, Deoria and nearby regions witnessed a fresh wave of infections. Hospitals were packed beyond capacity, parents waited outside emergency wards hoping to save their children, and doctors struggled to handle the overwhelming number of patients.

The Baba Raghav Das (BRD) Medical College in Gorakhpur became the centre of this crisis. Hundreds of children suffering from encephalitis were admitted every month during the peak season, and for years, the disease claimed hundreds of young lives annually. The situation had become so serious that encephalitis was no longer seen as a seasonal illness but as one of Uttar Pradesh’s biggest healthcare challenges.

When Yogi Adityanath assumed office as Chief Minister in 2017, the state faced the difficult task of controlling a disease that had remained largely unchecked for decades.

Instead of fighting only disease, the government built a statewide system targeting every cause of encephalitis

The Yogi government decided that encephalitis could not be defeated by hospitals alone. Rather than limiting efforts to treating patients after they became sick, the government adopted a comprehensive strategy aimed at stopping the disease before it spread.

Soon after taking office, the government introduced the Guidelines for Prevention and Treatment of Acute Encephalitis Syndrome, creating a coordinated action plan involving multiple departments. The Health Department became the nodal agency for the 38 encephalitis-affected districts, while departments including Medical Education, Urban Development, Rural Development, Panchayati Raj, Women and Child Welfare, Animal Husbandry and Basic Education worked together under a common framework.

This marked a significant shift in the state’s approach. Vaccination, sanitation, awareness, surveillance, treatment facilities and infrastructure development were all treated as equally important parts of the solution instead of isolated efforts.

Door-to-door vaccination and awareness protected millions of children

One of the biggest pillars of the government’s strategy was prevention through vaccination and public awareness.

In February 2018, Uttar Pradesh launched the Dastak campaign, which aimed to ensure that no child vulnerable to Japanese Encephalitis remained unvaccinated. Instead of waiting for families to visit health centres, ASHA workers, teachers and healthcare staff visited villages and households across affected districts.

They explained how encephalitis spreads, identified children showing early symptoms and encouraged parents to seek immediate medical care whenever warning signs appeared. Schools became centres for awareness programmes, while villages witnessed continuous information campaigns throughout the high-risk season.

The government believes that taking vaccination and awareness directly to people’s homes significantly improved early detection and reduced severe infections.

Sanitation and mosquito control became powerful prevention tools

The administration recognised that encephalitis could not be controlled without improving living conditions in the affected districts.

Along with healthcare interventions, the government integrated the campaign with the Swachh Bharat Mission and encouraged villages to improve sanitation and hygiene. Awareness programmes focused on using safe drinking water, maintaining cleaner surroundings and reducing mosquito breeding.

People were advised not to let children sleep directly on mud floors, to use India Mark-II hand pumps wherever available for safe water, and to keep pig shelters away from residential areas in vulnerable regions. Fogging operations and mosquito control measures were intensified to reduce the spread of Japanese Encephalitis.

Chief Minister Yogi Adityanath has repeatedly said that improved sanitation contributed significantly to reducing encephalitis-related deaths in the state.

Better hospitals improved treatment and emergency healthcare services

While preventive measures continued at the community level, the government also strengthened treatment facilities across eastern Uttar Pradesh.

Fifteen block-level encephalitis treatment centres and mini paediatric care centres were established in rural areas so that patients could receive timely treatment without travelling long distances. Block hospitals were equipped with at least three ventilators each to improve emergency response.

More than 3.5 lakh officers and government employees received specialised training on encephalitis prevention, early identification of symptoms and treatment protocols.

These improvements helped reduce the burden on tertiary hospitals such as BRD Medical College and ensured quicker medical attention for critically ill patients.

Cases and deaths declined after coordinated government action

The combined effect of vaccination, sanitation, awareness and healthcare improvements became visible within a few years.

According to Chief Minister Yogi Adityanath, Uttar Pradesh succeeded in reducing encephalitis cases by around 75 % and deaths by nearly 85 % after launching the coordinated campaign.

The transformation was particularly evident in Gorakhpur, once regarded as the epicentre of the disease. The Chief Minister has stated that between 1977 and 2017, nearly 600 children died every year due to Acute Encephalitis Syndrome in the district. In recent years, however, deaths have fallen dramatically, indicating a significant improvement in disease control.

Hospital admissions also declined sharply. BRD Medical College, which traditionally admitted 500 to 600 encephalitis patients every August, recorded a substantial reduction in admissions after preventive measures were expanded across the affected districts.

Japanese encephalitis cases that once numbered in the 100s have now dropped to a fraction of earlier levels

Government data also reflects a steady decline in Japanese Encephalitis.

Data Source: National Centre for Vector-Borne Disease Control

In 2017, Uttar Pradesh reported 693 JE cases and 93 deaths. The following years showed continuous improvement. In 2018, the state recorded 323 cases and 25 deaths. Cases further reduced to 235 in 2019, followed by 100 cases in 2020, 153 during 2021, 124 in 2022 and only 17 reported cases with zero deaths between January and July 2023.

The National Centre for Vector-Borne Disease Control reported that Japanese Encephalitis cases declined by more than 80 %, while deaths reduced by over 95 % during this period.

On September 9, Chief Minister Yogi Adityanath announced that no deaths had been reported in Uttar Pradesh due to Japanese Encephalitis, Chikungunya and Malaria between January 1 and September 7. He described the achievement as the result of sustained efforts launched after 2017 and said the government’s next objective is the complete eradication of the disease.

From hundreds of deaths, the state has been reporting zero encephalitis deaths since 2024. In 2026, while 3 cases of encephalitis have been reported so far, and the patients were successfully treated.

Uttar Pradesh’s encephalitis control model received international recognition from UNICEF

The state’s efforts also drew appreciation from the United Nations Children’s Fund (UNICEF).

UNICEF praised Uttar Pradesh’s large-scale immunisation programme against Japanese Encephalitis and Acute Encephalitis Syndrome under the Dastak campaign. The organisation highlighted the importance of combining vaccination with sanitation, awareness campaigns and active community participation instead of relying solely on hospital-based treatment.

Health workers, teachers and ASHA workers were recognised for ensuring that awareness and vaccination reached even remote villages across the affected districts.

The international recognition has strengthened Uttar Pradesh’s image as a state that managed to significantly reduce a disease that had troubled the region for generations.

What is Japanese Encephalitis, and how does it spread

Japanese Encephalitis (JE) is a viral disease transmitted through infected mosquitoes. The virus naturally circulates among pigs and certain species of birds before mosquitoes spread it to humans. It does not spread directly from one person to another.

The disease attacks the brain and can lead to high fever, headache, vomiting, seizures, confusion and unconsciousness. In severe cases, it can cause permanent neurological damage or death. Children remain the most vulnerable to the infection, making vaccination and early medical care especially important.

Since there is no specific cure for Japanese Encephalitis, public health experts emphasise vaccination, mosquito control, sanitation, early diagnosis and supportive treatment as the most effective ways to reduce deaths.

A public health success built through long-term planning

The fight against encephalitis in Uttar Pradesh shows how a long-standing health crisis can be tackled through coordinated action. By combining vaccination, door-to-door awareness, sanitation, stronger hospitals, trained healthcare workers and coordination across multiple departments, the state addressed the disease from several directions at the same time.

For decades, encephalitis represented one of the biggest health emergencies in eastern Uttar Pradesh, with thousands of families losing children and hospitals struggling every monsoon.

The decline in cases and deaths over the past several years has made the Uttar Pradesh model an important example of how sustained public health efforts can change the course of an epidemic.
