Antarctica Sees First H5N1 Bird Flu Case, Warns Scientists

Scientists caution of potential new pandemic with rising H5N1 bird flu cases. Since 2020, H5N1 spread to 26 countries, affecting mammals too. In 2020, 882 human cases reported with 52% fatality. Similar to COVID-19, H5N1 originates from animal-to-human transmission. Urgent research needed, while drugmakers develop vaccines. Animal migration due to climate change could exacerbate spread.
