Avian influenza

Avian flu is a viral infection that is highly contagious among birds and is found in domestic poultry and wild birds. Recently, infection has also been identified in mammals. All wild birds carry avian influenza viruses. Some are called “low pathogenic” strains because they cause no to minor symptoms. Some are called “high pathogenic” strains because they result in severe disease and high mortality rates. The spread and progress of avian flu is a continuing and evolving situation that is constantly changing. Right now, we are concerned about Highly Pathogenic Avian Influenza (HPAI) and the specific strain H5N1 which has killed hundreds of thousands of birds in the northern hemisphere and has spread very rapidly to the southern hemisphere.

Antarctic wildlife: Risk of Avian Influenza, News 13th September 2023

A risk assessment by SCAR Antarctic Wildlife Health Network (AWHN) predicts that Influenza virus H5N1 will hit the sub-Antarctic and Antarctic Peninsula this season with devastating impacts on seabird and pinniped colonies throughout the region.
