Nipah virus is forcing the world to quietly rehearse its next pandemic response. In India’s West Bengal, confirmed cases and urgent quarantines have triggered a chain reaction across Asia. Thailand now screens passengers at major airports, Nepal and Taiwan have raised their alert levels, and travelers from affected regions are monitored for the slightest sign of fever or confusion. Behind each checkpoint is a simple fear: one missed case could ignite a wider crisis.

Yet, unlike the chaos of early Covid, there is a fragile sense of control. India has faced Nipah eight times before and learned to respond fast, isolate contacts, and trace infections. Experts stress that, so far, outbreaks remain geographically limited, and health systems worldwide are better prepared to spot and contain rare threats. The danger is real, but so is the vigilance watching the skies.
