H5N1 virus detected in Hesaraghatta poultry centre near Bengaluru; no need for panic, says Dinesh Gundu Rao
As part of containment efforts, 7,444 birds were culled, and over 14,000 eggs and 2,250 kg of poultry feed were scientifically disposed of on April 15 under the supervision of the Animal Husbandry Department.

Context
The avian influenza virus was detected at a poultry training centre in Hesaraghatta, near Bengaluru. Following confirmation by the , rapid response teams initiated strict containment protocols to prevent the spread of the highly pathogenic virus.
UPSC Perspectives
Institutional & Policy Framework
India manages bird flu outbreaks through the detect and kill policy outlined in the . When an outbreak is confirmed by apex diagnostic laboratories like the (an institute located in Bhopal), authorities immediately establish containment zones (typically a 1 km radius) and cull infected and at-risk birds. Unlike some nations, India does not currently permit poultry vaccination against avian influenza, relying entirely on strict biosecurity, movement restrictions, and stamping-out procedures. To mitigate the severe economic impact on the poultry sector, farmers are compensated under the (ASCAD) scheme, which splits funding between the Centre and States.
Scientific & Public Health
is a highly pathogenic avian influenza (HPAI) strain caused by the Type A influenza virus, characterized by rapid spread and nearly 100% mortality in poultry flocks. From a UPSC science perspective, the primary concern is zoonotic spillover—the virus's ability to cross the species barrier to infect mammals and humans. While human-to-human transmission remains rare, direct contact with infected birds or contaminated environments can cause severe respiratory illness in humans with a high case fatality rate. The virus undergoes continuous genetic mutation (antigenic drift and shift), necessitating constant surveillance of migratory bird pathways, backyard poultry, and live bird markets.
Governance (One Health Approach)
Recurrent zoonotic outbreaks highlight the critical necessity of the , a multidisciplinary initiative endorsed by the . The One Health approach recognizes that human, animal, and environmental health are fundamentally intertwined. Avian influenza cannot be managed in silos by animal husbandry departments alone; it requires seamless coordination with wildlife authorities (to track migratory bird carriers) and public health officials (to monitor exposed human handlers). By building integrated disease surveillance systems, sharing laboratory networks, and establishing Rapid Response Teams (RRTs), the One Health framework ensures that emerging biological threats are contained before they escalate into human pandemics.
