Two 25-year-old nurses at a private hospital in Barasat, North 24 Parganas, were confirmed positive for Nipah virus (NiV) on January 13, 2026, by the National Institute of Virology, Pune. They had developed symptoms in late December 2025, progressing to neurological complications. The Viral Research Laboratory at Kalyani first flagged the cases on January 11.
As of January 21, the male nurse was recovering while the female nurse remained critical. Over 190 contacts were tested — all negative — with a mobile BSL-3 laboratory deployed by NIV Pune. The WHO assessed global risk as low. NiV has a case fatality rate of 40-75%, with no approved vaccine or specific antiviral. Fruit bats (Pteropus species) are the primary reservoir.
