Inter-population connectivity of southern elephant seals and the likely intra-species transmission pathways of high pathogenicity avian influenza

The paper assesses seal-to-seal transmission pathways of HPAI H5N1 among southern elephant seals using movement data, finding potential but unlikely spread between colonies.

Mass mortality of southern elephant seals during multi-species outbreak of HPAI H5N1 on sub-Antarctic Heard Island

The paper reports a multi-species outbreak of HPAI H5N1 on Heard Island, causing mass mortality in southern elephant seals and other seabirds, with drones used for monitoring.

Dispersal, adaptation and persistence of H5N1 in the sub-Antarctic and Antarctica

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

High pathogenicity avian influenza virus H5N1 clade 2.3.4.4b in Antarctica: Multiple Introductions and the First Confirmed Infection of Ice-Dependent Seals

This study confirms the first H5N1 infection in Antarctic ice-dependent seals and identifies multiple introductions of the virus in the region.

Mass mortality events in the sub-Antarctic Indian Ocean caused by long-distance circumpolar spread of highly pathogenic avian influenza H5N1 clade 2.3.4.4b

This study reports the arrival of HPAI H5N1 clade 2.3.4.4b in sub-Antarctic Indian Ocean islands, causing mass mortality in seals and birds, and identifies independent introductions from South Georgia.
