Two suspected Nipah cases in West Bengal; Centre deploys national response team
Two suspected Nipah virus cases have been identified in West Bengal, with testing reported at the VRDL, ICMR, AIIMS Kalyani. The Centre has deployed a National Joint Outbreak Response Team and shared guidance with the state surveillance system as containment and contact-tracing measures are stepped up.
Two suspected cases of Nipah virus disease have been identified in West Bengal, prompting a rapid response from the Centre and the deployment of a national expert team to assist the state. NDTV reported that the suspected cases were detected on January 11, 2026, at the Virus Research and Diagnostic Laboratory (VRDL) of the Indian Council of Medical Research (ICMR) at AIIMS Kalyani.
Given Nipah’s history as a high-risk zoonotic infection with significant mortality and the potential for rapid spread, officials have treated the development as a priority public-health event. The Centre has moved to support containment planning, including strengthening surveillance and ensuring coordination between state authorities and national institutes.
According to NDTV, a National Joint Outbreak Response Team has been deployed to help with containment and public health response measures. The team includes experts drawn from multiple institutions, including the All India Institute of Health and Public Hygiene in Kolkata, the National Institute of Virology (NIV) in Pune, the National Institute of Epidemiology (NIE) in Chennai, AIIMS Kalyani and wildlife experts under the Ministry of Environment, Forest and Climate Change.
The Centre has also shared guidelines on Nipah virus disease under the communicable disease alert framework with the State Integrated Disease Surveillance Programme (IDSP). This helps ensure uniform protocols for reporting, lab coordination, isolation practices and follow-up of contacts, which are central to preventing clusters from expanding.
As with earlier Nipah alerts in India, the immediate public-health priority is rigorous contact tracing and early identification of symptomatic contacts, along with infection prevention and control in healthcare settings. Authorities typically intensify community surveillance, review hospital readiness and reinforce risk communication to prevent panic while encouraging timely reporting of symptoms.
The alert also underscores why coordination between human health systems and animal/wildlife experts is important, since Nipah is a zoonosis and outbreaks often involve investigation of possible spillover routes. The inclusion of wildlife expertise in the deployed team reflects this One Health approach.
Officials will watch for confirmatory testing, any evidence of onward transmission, and whether additional suspected cases emerge. Until then, the operational focus remains on containment discipline: quick diagnosis, isolation, PPE compliance in hospitals, and close monitoring of high-risk contacts to stop a limited alert from turning into a larger outbreak.
