The Tamil Nadu government has sounded a high alert following reports of widespread crow mortality across the state, triggering an Avian Influenza Alert. This development mandates stringent biosecurity and clinical vigilance. The Department of Animal Husbandry, Dairying, and Fisheries consequently issued a comprehensive advisory for poultry farmers and wild bird handlers. Furthermore, the Directorate of Public Health and Preventive Medicine (DPH) released a separate communication, urging the public to follow strict safety protocols.

Key Clinical Protocols for Avian Influenza Alert

The DPH advises individuals to seek immediate medical assistance if they experience flu-like symptoms. These symptoms include a cough, cold, fever, or breathing difficulties. Therefore, clinicians must maintain a high index of suspicion, especially for specific at-risk groups. Specific caution applies to those working in slaughterhouses and personnel who handle sick or dead birds. Additionally, the Animal Husbandry department directed officials to intensify surveillance. They must step up vigil to detect any unusual sickness or mortality among crows, migratory birds, and commercial poultry. The new protocols strictly instruct veterinary staff to refrain from conducting autopsies in the field. Instead, they must refer all carcasses to designated Regional Disease Diagnostic Labs for containment and clinical accuracy. Finally, the advisory mandates that authorities must either burn or bury dead birds deep to prevent the infection's spread through scavenging.
