Karnataka says it has contained an H5N1 bird flu outbreak near Bengaluru after a 10-day surveillance drive found no human cases. (timesofindia.indiatimes.com) (deccanherald.com) The outbreak was detected at the State Poultry Rearing Training Centre in Mathkuru village, Hesaraghatta, and officials said the first report was received on April 14. Karnataka’s Health and Family Welfare Department worked with the Animal Husbandry and Veterinary Services Department on the response. (hindustantimes.com) (timesofindia.indiatimes.com) H5N1 is a strain of avian influenza, or bird flu, that spreads mainly among birds but can infect people after close exposure to sick poultry or contaminated environments. That is why the human response focused on fever and breathing symptoms, not just dead birds. (who.int)) (cdc.gov) Health teams said they screened 28,172 people in 22 villages within a 10-kilometer radius of the center. Hospitals and primary health centers were told to watch for influenza-like illness and severe acute respiratory infection, the two syndromes India uses to catch possible spillover early. (thehindu.com) (idsp.mohfw.gov.in) Officials also tested staff members who had contact with the poultry center and said no human infection was found. The state said antiviral drugs, personal protective equipment and testing arrangements were kept ready during the operation. (deccanherald.com) (ndtv.com) Animal-health measures were broader than the human surveillance window. Reports from the containment phase said authorities culled thousands of birds, sealed a 3-kilometer zone around the center and halted poultry-related activity in the area for 90 days. (oneindia.com) (newsfirstprime.com) India’s avian influenza playbook has long paired poultry culling and movement controls with laboratory surveillance for respiratory illness in nearby people. The Integrated Disease Surveillance Programme says its influenza lab network was expanded after earlier H5N1 outbreaks in poultry to monitor possible human transmission. (idsp.mohfw.gov.in) The immediate result in Hesaraghatta is narrow but important: a confirmed poultry outbreak near Bengaluru did not turn into a detected human cluster over the first 10 days of monitoring. Karnataka officials said containment and watch measures will continue under protocol. (thehindu.com) (hindustantimes.com)
