New test reveals Nipah virus spread among Indian pigs, raising spillover concerns

For decades, Nipah virus has moved silently from fruit bats through pigs before reaching humans, leaving fatal encephalitis in its wake across South and Southeast Asia. Indian researchers have now built a homegrown diagnostic tool capable of detecting the virus's presence in pig populations across Kerala — a state where bats, livestock, and people share intimate proximity.

The question it leaves open is whether kno
