Nipah virus infection
Latest update
On 11 June 2026, the Kerala State Health Department confirmed one laboratory confirmed case of Nipah virus (NiV) infection in Kozhikode district, Kerala State, India. The case is an adult male who developed symptoms on 30 May 2026 and was hospitalized on 10 June 2026. He presented with neurological manifestations and at the time of reporting is on ventilatory support in an intensive care unit (ICU). As of 18 June 2026, a total of 104 contacts had been identified and were under monitoring, including health and care workers, with no reported secondary cases to date. NiV is a zoonotic disease transmitted to humans through infected animals, or through consumption of fruits or fruit products, such as raw date palm juice contaminated with the saliva, urine, or excreta of infected bats, as well as close contact with infected individuals. The current event involves a single confirmed case, with no secondary transmission identified to date. Public health measures are in place, including isolation, contact tracing, and enhanced surveillance. However, as the source of infection has not yet been identified and given the known presence of animal reservoirs, additional cases cannot be excluded.
