A new study from the University of Hong Kong has shown that over 250 million poultry worldwide have had to be culled due to Highly Pathogenic Avian Influenza (HPAI) since the disease’s resurgence in 2020-2021.

This subtype of the H5N1 variant has become increasingly infectious to wild birds, and over this period of 2020-2021, 100,000 wild birds of 400 different species have died.
