An outbreak of the Nipah virus in India’s West Bengal state has prompted heightened health vigilance across parts of Asia, with several countries strengthening airport and border screening measures. Nipah virus is a zoonotic infection that can spread from animals to humans and, in some cases, between people, and is associated with a high fatality rate. While the overall risk to travelers remains low, authorities are closely monitoring the situation.

Indian health officials have confirmed two Nipah virus cases since December, reportedly among healthcare workers. Nearly 200 people identified as close contacts were traced, monitored, and tested, with no further cases detected. In response, countries including Thailand and Nepal have introduced enhanced screening for travelers arriving from affected regions.

Travelers arriving from parts of India have been subject to health declarations and symptom screening at selected international airports in Asia. Although no cases have been reported outside India, authorities say these measures are precautionary and aim to detect potential infections early and prevent cross‑border spread.

Travel advice: Travelers to or from affected areas should monitor their health closely during and after travel, particularly within two weeks of arrival. Avoid contact with sick individuals, do not consume unwashed fruit or unpasteurized products, and practice strict hand hygiene. Anyone developing symptoms such as fever, headache, or respiratory illness after travel should seek medical advice promptly and inform healthcare providers about their recent travel history.
