Health authorities in India have officially confirmed two cases of the deadly Nipah virus in the eastern state of West Bengal, with all known contacts traced and testing negative so far.
The cases, detected in late December 2025, involved healthcare workers and prompted rapid contact tracing. India’s health ministry emphasized that only two confirmed infections have been recorded and warned against speculative or inaccurate figures circulating in media reports.
In response to the news, several Asian countries including Thailand, Malaysia, Singapore, Hong Kong, Nepal and China have stepped up airport screenings and health surveillance at points of entry to curb any potential spread. Measures include temperature checks, health declarations, designated aircraft parking zones, and targeted passenger assessments.
The World Health Organization (WHO) classifies the Nipah virus as a priority pathogen, citing its high fatality rate—between approximately 40% and 75%—and the absence of an approved vaccine or specific treatment.
Nipah virus is a zoonotic disease, typically transmitted from animals like fruit bats or pigs to humans, and can sometimes spread through close contact with infected individuals. Initial symptoms may resemble common illnesses but can rapidly progress to severe neurological complications.
Public health experts say that while the virus is rare and not easily transmissible between humans, vigilance and robust screening are crucial to deter cross-border spread.
