Health authorities across Asia are intensifying health screenings at major airports after a recent Nipah virus outbreak in India’s West Bengal raised concerns about cross-border spread. The move comes as nations implement measures similar to those used during the COVID-19 pandemic in a bid to protect travellers and curb transmission.

The outbreak, confirmed in West Bengal, has seen several infections among healthcare workers. While officials report a limited number of cases, authorities are closely tracking potential contacts and continuing epidemiological investigations.
Nipah virus (NiV) is a zoonotic pathogen that originates in animals — particularly fruit bats — and can spread to humans through contact with contaminated food, infected animals, or close human contact. Early symptoms include fever, headache, muscle pain, vomiting, and sore throat, while severe cases can lead to respiratory distress, encephalitis, and even fatal brain inflammation. The World Health Organization classifies Nipah as a high-priority virus due to its high fatality rate and lack of vaccine or specific treatment.
In response, airports in Thailand, Nepal, and Taiwan have reintroduced COVID-style health checks for travellers arriving from affected regions, particularly West Bengal. Protocols include fever screening, health declaration forms, and issuing “health advisory cards” to travellers outlining symptoms and steps to take if unwell. Some countries also have isolation protocols for symptomatic passengers upon arrival.
Despite heightened surveillance, health experts emphasize that the overall risk to most travellers remains low, especially if they have no direct exposure to infected areas or individuals. Passengers returning from India are advised to monitor their health closely, report symptoms promptly, and follow all local health guidance.
Officials stress continued vigilance, early detection, and hygiene practices as key measures in managing the outbreak while allowing travel and trade to continue safely.
