India tests zoo bats for Nipah virus after human cases in West Bengal.

The National Institute of Medical Research is testing bats at Kolkata's Alipore Zoo for the Nipah virus using RT-PCR, following two confirmed human cases in West Bengal. Teams collected blood and swab samples early Thursday and Friday, working with health and forest departments to minimize disruption. The samples are being analyzed by the National Institute of Virology and ICMR, with results expected in days. The effort is part of a broader surveillance campaign across West Bengal, including sampling in North 24 Parganas and upcoming work in Nadia district. Authorities are taking precautionary measures to prevent potential outbreaks.
