Tamil Nadu intensifies surveillance after H5N1 Bird Flu detected in crows
Tamil Nadu has confirmed H5N1 avian influenza in crows, prompting intensified state-wide surveillance.
The union government verified the highly pathogenic H5N1 virus in crow samples from Kancheepuram district, tested at ICAR-NIHSAD in Bhopal on January 21, 2026. Reports indicate 1,000-1,500 crow deaths in Chennai areas like Adyar, Velachery, Thiruvanmiyur, Pallikaranai, and along ECR/OMR. No cases in poultry or humans have been confirmed yet.
Authorities are ramping up biosecurity, including deep burial or incineration of dead birds, active surveillance of poultry, ducks, wet markets, farms, and wild birds. A One Health approach coordinates animal husbandry, wildlife, forest, and health departments, with mandates for immediate reporting of unusual bird deaths. The Centre requires regular updates from Tamil Nadu on cases, controls, and epidemiology.
Residents should avoid touching dead birds and report sightings to local authorities promptly. Health officials advise caution near bird habitats, proper hygiene, and no handling of sick or dead crows to minimize risks.
