Nipah Virus: Asia's Neglected Deadly Threat

Scientists are sounding the alarm about the Nipah virus, a recurrent, lethal, and preventable zoonotic disease first identified in Malaysia in 1999. Despite repeated emergences in South and Southeast Asia, the virus is not receiving adequate attention, say correspondence authors in The Lancet.

Recent outbreaks in India and Bangladesh are not isolated incidents but recurring reminders of Nipah's high mortality rate and potential for healthcare worker infections. As of January 26, 2026, two nurses in West Bengal were confirmed infected, with one succumbing to the illness in February.

Factors such as deforestation, urban expansion, and intensified agriculture are increasing human-bat interactions, thereby elevating the risk of Nipah virus transmission. This spillover is amplified by practices like pigs magnifying the disease risk and bats contaminating food sources.

Translating knowledge into effective action has been poor, with surveillance often initiated too late and research funding being sporadic. Southeast Asian nations like Cambodia, Thailand, and the Philippines share similar risk factors due to high populations, growing agriculture, and abundant fruit bats.

The authors advocate for sustained One Health strategies, linking human, animal, and environmental health, alongside regular funding and regional coordination. Proactive surveillance, ecological monitoring, and cross-border communication are critical and cannot await the next outbreak.
