Research: Avian influenza (influenza A H5N1): risk to human health

Research: Avian influenza (influenza A H5N1): risk to human health A record number of cases of avian influenza virus infections or ‘bird flu’ were confirmed across England, Scotland, and Wales in wild and captive birds last winter (2021 to 2022).

As we head into winter 2022 to 2023 there have been further increases in detections recently, both in wild and captive bird flocks.

Avian influenza virus infections which cause disease in humans are very rare but can cause serious disease and deaths. UK Health Security Agency
