The World Health Organization said it has received reports of three new confirmed H5N1 cases in wild birds across northern Europe, adding to concerns about seasonal spread of avian influenza. The update comes as health and agriculture authorities step up monitoring ahead of potential outbreaks in poultry flocks.

Officials are focusing on surveillance around farms, where contact between infected wild birds and domestic birds can increase the risk of transmission. H5N1 has circulated in wild bird populations in several regions in recent years, forcing repeated containment measures and biosecurity checks.

While the latest reports involve birds rather than human cases, the detections underscore why public-health agencies continue to track avian influenza closely during warmer months, when migration patterns and farm exposure can complicate disease control.

Authorities have urged poultry operators to strengthen precautions, including limiting contact with wild birds and reporting unusual illness or deaths quickly. The WHO says continued surveillance remains essential to reduce the risk of wider spread.
