Panic has gripped Tamil Nadu, including Chennai, after hundreds of crows were found dead across several localities, triggering fears of a bird flu outbreak. Laboratory tests have confirmed the presence of the H5N1 avian influenza virus in the dead birds, raising concerns among health authorities.
H5N1 Virus Confirmed in Dead Birds
Samples collected from dead crows were sent to the ICAR–National Institute of High Security Animal Diseases (NIHSAD) in Bhopal for testing. The results confirmed that the birds were infected with the highly pathogenic H5N1 avian influenza virus, commonly known as bird flu.
Authorities Step Up Containment Measures
Following the confirmation, state health and animal husbandry departments have initiated swift containment measures to prevent further spread of the virus. Authorities have directed that all dead crows and poultry be disposed of strictly as per biosecurity protocols, either by incineration or by deep burial.
Advisory Issued for Public Safety
The health department has issued advisories urging the public to avoid contact with dead or sick birds and to immediately report unusual bird deaths to local authorities. Surveillance has been intensified to detect any signs of transmission among wild birds, domestic poultry, or humans.
Centre Urges Enhanced Surveillance and Biosecurity
The Union government has asked the Tamil Nadu government to strengthen monitoring, biosecurity, and disease control measures to ensure the virus does not spread from birds to humans. Special focus is being placed on preventing cross-species transmission.
Crow Deaths Reported from Multiple Chennai Localities
Crow deaths were reported from several areas, including Adyar, Velachery, Thiruvanmiyur, and Old Mahabalipuram Road (OMR). Following these reports, animal health teams began field investigations in late January and collected samples for laboratory analysis.
Vigilance Increased Across the State
With the confirmation of H5N1, authorities remain on high alert across Tamil Nadu. Continuous monitoring and rapid response teams have been deployed to curb the outbreak and ensure public health safety.
