An outbreak of the Nipah virus in India’s West Bengal state has prompted neighboring countries to enhance screening measures at airports and border crossings. The virus, which has infected five healthcare workers—one critically—has no approved vaccine or treatment, raising concerns across Asia.
Immediate Action & Core Facts
Thailand and Nepal have begun screening passengers arriving from West Bengal, while 110 contacts of the infected individuals remain under quarantine. The Nipah virus, transmitted from animals like bats and pigs, has a fatality rate of 40% to 75%.

Transmission and Symptoms
The virus spreads through direct contact with infected animals or contaminated food. Symptoms range from fever and muscle pain to severe encephalitis, with an incubation period of 4 to 14 days. The World Health Organization lists Nipah among its top ten priority diseases due to its epidemic potential.
Past Outbreaks and Global Concerns
The first recorded outbreak occurred in 1998 in Malaysia, killing over 100 people. In China, social media discussions have surged ahead of the Lunar New Year, with some users expressing fear of travel restrictions. Chinese health experts, however, say the virus is difficult to transmit and unlikely to cause a domestic outbreak.
Travel and Policy Implications
China and India recently eased visa rules to boost travel, but the outbreak has raised concerns about cross-border transmission. The Lunar New Year travel rush, spanning February 2 to March 13, adds urgency to monitoring efforts. While no cases have been reported outside India, heightened vigilance remains in place across Asia.
