Only two confirmed cases reported in West Bengal, outbreak contained with strict surveillance; airport screenings increase across Asia.
Current Status of the Nipah Virus in India
India has reported a small outbreak of the Nipah virus in West Bengal, but authorities say the situation is contained and under constant monitoring. Multiple media reports have sparked public attention and some misinformation, making it essential to clarify the facts and timeline of events.
Nipah virus is a zoonotic infection—transmitted from animals (especially fruit bats) to humans—and is known for its high fatality rate and lack of a licensed vaccine or specific antiviral treatment.
Confirmed Cases and Containment Efforts
According to the Union Health Ministry and National Centre for Disease Control (NCDC) reports:
- Only two confirmed cases of Nipah Virus Disease (NiVD) have been reported in West Bengal since December 2025.
- Both cases were promptly addressed with enhanced surveillance, laboratory testing, contact tracing, and quarantine protocols.
- A total of 196 contacts linked to these cases were identified, traced, monitored, and tested, and all were asymptomatic and tested negative.
Officials have emphasised that there are no new confirmed cases beyond these two, and the outbreak has not spread across India.
Why the Alert Started: Earlier Reports and Tests
Prior to the official confirmation, healthcare workers in West Bengal were identified as suspected Nipah cases, leading to heightened vigilance in local hospitals. These reports included healthcare staff being treated and under observation while samples were tested in specialised labs.
Symptoms, Spread and Health Risks
Nipah virus symptoms often begin with fever, headache, muscle pain, dizziness and respiratory issues. In severe cases, the infection can progress to encephalitis (brain inflammation) and coma, which carries a high risk of death.
The virus spreads:
- From fruit bats to humans
- Through contaminated food
- Via close contact with infected bodily fluids
There is no vaccine for Nipah, and treatment is limited to supportive care
Public Health Response and Preparedness
India’s health authorities have taken proactive measures:
- Quarantine and monitoring of contacts linked to confirmed cases
- Laboratory testing and field investigations
- Surveillance and strict infection control protocols in affected areas
Medical experts also underline that early diagnosis, isolation and contact tracing are key to preventing the virus’s spread, especially among caregivers and healthcare workers.
Airport Screenings and Regional Impact
While the outbreak remains limited to West Bengal, several Asian countries including Thailand, Nepal, Taiwan and Malaysia have introduced or enhanced airport health screenings as a precaution for travellers from India. These measures include temperature checks, health declarations, and additional screening for respiratory symptoms.
Officials say such screenings differ from earlier COVID-19-style border controls and are designed to identify symptomatic travellers early, rather than indicate widescale spread.
Historical Context of Nipah in India
India has experienced sporadic Nipah outbreaks before:
- 2001 and 2007 – Past outbreaks in West Bengal
- 2018, 2021, 2023 and 2024 – Notable outbreaks in Kerala, with high fatality rates and strict containment measures by health authorities.
The virus remains endemic in some regions, meaning isolated clusters may reoccur, but robust surveillance and rapid response systems have so far prevented widespread transmission.
Government Advisory and Public Guidance
Health officials urge the public to:
- Stay calm and rely on verified official updates
- Avoid contact with fruit bats and sick animals
- Practice good hygiene and seek medical advice if symptoms appear
Authorities continue to monitor the situation and affirm that all necessary public health measures are in place to manage and control the risk.
