No human cases of the highly pathogenic avian influenza A (H5N1) have been detected after a 10-day intensive surveillance and containment operation carried out by the State Health Department, following the outbreak at the State Poultry Rearing Training Centre in Mathkuru village, Hesaraghatta near Bengaluru on April 14, 2026.
The outbreak was confirmed through laboratory testing at the National Institute of High Security Animal Diseases (NIHSAD), Bhopal, prompting immediate deployment of State and district Rapid Response Teams, along with teams from Hesaraghatta and Sonnenahalli Primary Health Centres.
Authorities demarcated an infected zone within a 0–3 km radius and a surveillance zone of 3–10 km, and initiated containment measures as per established biosecurity protocols. All birds at the affected facility were culled, and eggs and contaminated feed were safely disposed of.
Surveillance across 22 villages
Officials said surveillance was carried out across 22 villages within a 10 km radius, covering a population of 28,172. Multiple rounds of field visits and sanitation measures were undertaken during the 10-day period in accordance with protocol.
