Highly pathogenic avian influenza (HPAI) in South America, 2022-2025: temporality, affected species, and the southwards expansion to the Antarctic region

2025-10-05

Abstract excerpt

<h4>ABSTRACT</h4> The H5N1 highly pathogenic avian influenza (HPAI) virus has caused severe global losses, reaching South America in 2022 and Antarctica in 2024. Here we synthesize outbreak reports submitted to the World Organization for Animal Health (WOAH) by South American countries and document the virus’s unprecedented expansion into Antarctica, affecting wild birds, wild mammals, and domestic poultry.
