Chennai: The Tamil Nadu Public Health Department has issued a precautionary advisory to the public and poultry farm owners following laboratory confirmation that the recent, unexplained deaths of over 100 crows in Chennai, including Adyar, were caused by the H5N1 avian influenza (bird flu) virus. The department has urged people not to touch any dead birds with bare hands and to report such incidents immediately.
Crow deaths in clusters prompt investigation and confirmation
In recent days, clusters of crow deaths were reported in several parts of the city, with birds found dead in parks and public spaces, causing concern among residents. The carcasses were collected and sent to the Tamil Nadu Veterinary and Animal Sciences University (TANUVAS) for analysis. The test results have now confirmed the presence of the highly pathogenic H5N1 virus, indicating an active spread of bird flu in the local avian population.
Official Advisory: Do not touch, report and dispose safely
The Public Health Department’s advisory explicitly warns:
-
Do not touch dead crows, chickens, or any other birds with bare hands.
-
Report any instances of mysterious bird deaths to the nearest Veterinary or Animal Husbandry Department.
-
Safely dispose of carcasses by burying them 8-10 feet deep or through cremation, following official guidance.
-
Poultry farm owners are advised to maintain heightened biosecurity and vigilance.
Human risk: “No cases reported,” but caution urged
The department has clarified that no human cases of bird flu have been reported so far in the state. However, it cautioned that while the H5N1 virus does not easily infect humans, direct contact with infected birds or contaminated environments can pose a risk. Symptoms in humans can include high fever, cough, sore throat, muscle aches, and in severe cases, pneumonia or acute respiratory distress. The public is advised to seek immediate medical consultation if such symptoms appear after potential exposure.
