Laboratory tests of hundreds of dead crows found across Chennai last month confirmed the presence of the H5N1 virus on Friday. Health authorities issued a public advisory signaling the outbreak of avian influenza in the region. While efforts are underway to contain the flu and curb further transmission, the carcasses of crows and poultry are directed to be incinerated or deeply buried as per biosecurity protocols.
Public urged to avoid contact with dead birds
The general public has been strictly warned against touching or removing dead birds and has been advised to alert authorities. The Tamil Nadu Animal Husbandry Department’s Animal Disease Intelligence Unit collected samples from Chennai in late January and sent them to Bhopal’s ICAR-NIHAS laboratory. Tests confirmed that a highly pathogenic H5N1 strain, called zoonotic potential, was present in the dead birds. In the wake of the crow fatalities, the Union Ministry of Animal Husbandry has written to the Tamil Nadu Chief Secretary, seeking immediate field surveillance to prevent the H5N1 flu from spreading.
