Indian health authorities have reported that a recent Nipah virus outbreak in West Bengal has been contained after confirming two cases, prompting several neighboring countries to strengthen airport screenings and health checks for travelers from India.
The Ministry of Health and Family Welfare said Tuesday that both cases were detected since December 2025 and that all identified contacts—196 people in total—had been quarantined and tested, with no additional positive cases reported. Authorities emphasized that the situation is under continuous monitoring and that all necessary public health measures have been implemented.
Nipah virus is a zoonotic pathogen first identified in Malaysia during the 1990s. It spreads through fruit bats, pigs, and human-to-human contact, causing high fevers, convulsions, vomiting, and severe respiratory symptoms. There is currently no vaccine, and treatment is limited to supportive care to manage complications. The World Health Organization estimates the fatality rate of Nipah infections at 40% to 75%, significantly higher than that of COVID-19.
Regional Response
While no cases have been confirmed outside India, several Asian nations have tightened precautionary measures. Indonesia and Thailand enhanced airport health screenings, requiring temperature checks, health declarations, and visual inspections for travelers arriving from West Bengal. Thailand has installed thermal scanners at arrival gates in Bangkok’s Suvarnabhumi Airport for direct flights from the region.
Myanmar’s Health Ministry advised against nonessential travel to West Bengal and urged travelers to seek immediate medical care if symptoms appear within 14 days of arrival. Fever surveillance protocols established during the COVID-19 pandemic have been intensified at airports, and local hospitals have been equipped with additional testing and medical supplies.
Vietnam instructed local authorities to enforce strict food safety standards and increase monitoring at border checkpoints, health facilities, and communities. China has also strengthened border disease prevention measures, including enhanced medical staff training, risk assessments, and expanded testing capabilities.
Historical Context
West Bengal has previously experienced Nipah outbreaks in 2001 and 2007, while southern Kerala state has been the site of recent cases. A significant outbreak in Kerala in 2018 claimed at least 17 lives, underscoring the virus’s high lethality and the importance of early containment.
Indian officials have stressed that early media reports suggesting a surge in Nipah cases were inaccurate, and authorities continue to monitor the situation closely to prevent further transmission.
