The study sampled skuas on the Antarctic Peninsula and found HPAI H5N1 in all but one carcass, indicating the virus is established in Antarctica despite low prevalence.

The study conducted migratory bird and marine mammal surveillance in 2025 and found no evidence of HPAI H5N1 2.3.4.4b in Australia, though low pathogenicity avian influenza was detected.

The study surveils migratory shorebirds and seabirds in Australia in 2024, finding no HPAI H5N1 but detecting diverse LPAI viruses, including mosaic H3N7 and H4N7 from Red-necked Stints and a Eurasian H1N7.

This study tracks the spread and evolution of H5N1 in the sub-Antarctic and Antarctica, revealing long-distance dispersal and mammalian-adaptive mutations.

The paper reports mass penguin mortality in Antarctica due to avian cholera, not H5N1 HPAIV, highlighting the need to consider avian cholera in differential diagnoses.

This study reports H5 HPAIV causing high mortality in skuas in Antarctica, highlighting risks to their populations and potential role in virus spread.

The paper reports the continued absence of HPAI H5N1 lineage 2.3.4.4b and antibodies against it in migratory birds in Australia during October-December 2023.
