Nipah Virus Outbreak in West Bengal Triggers Regional Alerts Across Asia
In response to the growing threat, nations including Thailand and Nepal have intensified health screenings for travelers arriving from India.
According to international media reports, Thailand has implemented specialized monitoring at three major airports that receive direct flights from West Bengal. Similarly, Nepal has mandated rigorous screening for passengers at Kathmandu’s international airport and along its various land borders with India.
The current alarm follows reports earlier this month of five healthcare workers in West Bengal contracting the virus, one of whom remains in critical condition. To contain the spread, authorities have placed at least 110 individuals who came into contact with the infected patients under strict quarantine.
Health experts classify Nipah as a "zoonotic" virus, primarily transmitted from animals—specifically fruit bats or pigs—to humans. The virus is exceptionally lethal, with fatality rates ranging from 40% to 75%. The lack of an effective vaccine or specific treatment has made it a top priority for the World Health Organization (WHO).
Nipah virus is not a new phenomenon in South Asia. Since 2001, Bangladesh has recorded over 100 deaths linked to the virus, while West Bengal previously faced outbreaks in 2001 and 2007. However, the current surge has triggered preemptive measures from neighboring countries wary of the virus spreading across borders through international travel.
