The deadly bird flu strikes Antarctica: Researchers from Jena warn of a major threat
Researchers from Jena raised concerns after discovering a serious outbreak of avian influenza in Antarctica, warning that the H5N1 virus may spread more widely than initially observed. The findings indicate significant risks to local wildlife.
The virus was first discovered in Antarctica in October 2023 and recently appeared on King George Island near the northern coast of the continent. Christina Brown from the Institute of Biodiversity, Ecology and Evolution at Friedrich Schiller University Jena confirmed the discovery of the virus during a recent expedition.
During fieldwork earlier this year, the research team found 52 dead birds, including scoters, southern giant petrels, and polar albatrosses. Not all birds were tested for H5N1, but the notable mortality rate indicates a significant outbreak. Brown confirmed, "Something is happening there."
Markus Bernhardt-Römermann, a Brown fellow, warned that the actual number of infected birds could be much higher, as dead animals are quickly consumed or dragged away. The virus primarily spreads through saliva, making crowded penguin colonies particularly vulnerable.
Scientists say that the long-term consequences are uncertain. Some skua birds may have developed immunity, but the flu could lead to the extinction of some local populations. Penguins, which gather to stay warm, face a significant risk, raising concerns about the future of bird species in Antarctica.
