Suspected H5 Bird Flu Outbreak Kills Hundreds of Seal Pups on Sub-Antarctic Island
Scientists observed unusual elephant seal deaths with neurological and respiratory symptoms possibly linked to H5N1 bird flu, pending lab confirmation after samples return to Australia.
- On Friday, Australian Antarctic Program scientists observed signs consistent with H5 avian influenza on Heard Island and reported unusual elephant seal deaths pending lab confirmation.
- After outbreaks on Kerguelen and Crozet islands, authorities mounted a mission aboard RSV Nuyina, following H5 avian influenza detection less than 450km from Heard Island.
- Scientists observed neurological and respiratory symptoms in elephant seals, including torticollis and animals collapsing, while Heard Island’s remoteness about 4,000km south-west of Perth complicated testing.
- Samples have been collected and will travel with the RSV Nuyina for testing in Australia; the Australian federal government has invested more than $100 million in preparedness while urging vigilance.
- Dr Michelle Wille warned the disease had been `catastrophic everywhere` and South America lost more than 30,000 sea lions, 17,000 seal pups and at least 650,000 native birds.

Suspected H5 bird flu outbreak kills hundreds of seal pups on sub-Antarctic island
Hundreds of dead seal pups have been found on Heard Island, where Australian scientists say they observed signs consistent with H5 avian influenza. Australia’s Department of Agriculture said the observation has not yet been confirmed as bird flu, but scientists reported unusual levels of elephant seal deaths on the island, consistent with patterns seen in previous mass mortality events linked to avian influenza. Australian scientists reported di…
Scientists fear bird flu outbreak after elephant seal deaths on Heard Island
Scientists suspect a deadly strain of bird flu, H5N1, has infected wildlife on Heard Island after observing a high mortality rate in elephant seals on the Australian territory in the sub-Antarctic.
