What veterinarians should know about Nipah spillover risk

India reported two laboratory-confirmed Nipah virus infections in West Bengal in January 2026, both involving healthcare workers at the same private hospital in Barasat, with epidemiologic linkage and no evidence of community spread so far. WHO said the cases were notified on January 26, and the European Centre for Disease Prevention and Control described the risk to Europeans as very low. The event has renewed attention on Nipah as a high-fatality zoonotic virus carried by fruit bats, with spillover risk shaped by bat-human-livestock interfaces, contaminated food sources, and, in some outbreaks, intermediate animal hosts such as pigs.

Why it matters: For veterinarians, this isn’t just a human health story. WOAH lists Nipah as a notifiable animal disease, and FAO says spillover risk rises where bat habitat overlaps with livestock systems or human settlements. While the current West Bengal cluster appears healthcare-associated rather than livestock-driven, past outbreaks have involved transmission through pigs, and other domestic species have been infected. That makes farm biosecurity, protection of feed and water from bat contamination, rapid reporting of unusual neurologic or respiratory illness in animals, and One Health coordination especially relevant in regions where fruit bats and domestic animals mix.

What to watch: Watch for whether Indian authorities identify any animal involvement, publish additional surveillance findings, or confirm that the January 2026 cluster remains limited to the original linked cases. (who.int)
