Karnataka health authorities have confirmed that the recent avian influenza outbreak reported in Bengaluru has been successfully contained, with no cases of human infection detected.

The outbreak was first identified on April 14 at a government poultry training facility in Hesaraghatta on the outskirts of Bengaluru. Laboratory testing later confirmed the virus as the H5N1 strain.

Swift action helped contain spread

Following confirmation, state and district rapid response teams, along with local health workers, launched containment measures to prevent further spread.

Officials created a three-kilometre infected zone around the site and extended surveillance up to 10 kilometres. Veterinary teams culled all birds at the affected facility, while eggs and contaminated feed were safely disposed of under biosecurity protocols.

28,000 residents monitored

Over a 10-day monitoring period, health teams screened more than 28,000 residents across 22 villages in the surveillance zone. Multiple rounds of health checks and sanitation drives were conducted as per safety guidelines.

Samples taken from quarantined staff members during the operation tested negative for the virus. Additional samples have been sent for further testing, though authorities stressed that no human infections have been found in the affected or nearby areas.

Hospitals on alert

Hospitals and healthcare centres across Bengaluru have been instructed to remain alert for influenza-like illness and severe respiratory symptoms. Authorities have also directed facilities to maintain stocks of protective gear, antiviral medicines and testing supplies.

The affected poultry premises have now been sanitised, though poultry-related activity there will remain suspended for three months as a precautionary measure.

Public urged to stay calm

Officials advised residents not to handle sick or dead birds and to report such incidents immediately. They also reassured the public that properly cooked poultry products remain safe for consumption.

Authorities urged citizens to rely on official updates while monitoring continues
