A new outbreak of the Nipah virus threatens to rekindle fear across Asia as airport screenings return, echoing the era of COVID-19 restrictions.
Nipah Virus Emergence in West Bengal
The Nipah virus, first identified in 1999, has reemerged in West Bengal, India, with five confirmed cases linked to a private hospital in Barasat. The virus, known for its high fatality rate and potential to cause brain-swelling encephalitis, has sparked major health concerns. Health officials have quarantined approximately 100 individuals who were in close contact with the infected, as two nurses remain in critical condition. The outbreak has prompted a swift response to prevent further spread.

In response to the outbreak, Thailand has started implementing screenings at key airports, including Suvarnabhumi and Don Mueang, for arrivals from West Bengal since January 25, 2026. Nepal and Taiwan have followed suit, introducing thermal screenings at airports and land borders. These measures are reminiscent of the stringent checks during the COVID-19 pandemic, aimed at curbing the virus’s spread beyond India’s borders.
International Reaction and Precautions
The World Health Organization has prioritized Nipah for research and development, given there is no vaccine or approved treatment. The virus spreads through close contact, making household and healthcare settings particularly vulnerable. Despite its lower transmissibility compared to COVID-19, the high fatality rate necessitates stringent precautions. The current measures aim to prevent an international health crisis by controlling the virus’s reach at its source.
Health departments across Asia are working tirelessly to implement effective screening processes. Thailand’s Department of Disease Control has reported smooth operations and passenger cooperation, reflecting a collective effort to safeguard public health. The international community remains on high alert, monitoring for any signs of the virus spreading outside India.
