Spanish scientists discover “a massive outbreak” of deadly bird flu in Antarctica. An international expedition finds dozens of Antarctic skua carcasses and shows that the disease spreads across the virgin continent.

“We saw 80 alive and 50 dead. That's crazy," warns the virologist from the Severo Ochoa Molecular Biology Center (CSIC) in Madrid. A new subtype of the virus, called H5N1 2.3.4b, emerged in 2021 and has since caused the culling of hundreds of millions of birds.
