H5N1 Bird Flu Spreads Widely, U.S. Declares Emergency

Aug 7, 2024, 02:19 PM

Concerns are rising over the spread of the H5N1 bird flu, which has now affected 485 bird species and 48 mammal species, including seals, foxes, and polar bears. The current panzootic is attributed to modern livestock production methods, where the virus jumped from domestic poultry to wild birds. Health officials are particularly worried about the potential for reassortment, where bird flu and seasonal flu could exchange genetic material, potentially creating a new pathogenic strain that could spread to humans. The U.S. Department of Health and Human Services has declared an emergency for influenza A viruses, including H5N1, under the Federal Food, Drug, and Cosmetic Act to prepare for potential outbreaks. Experts from organizations like the WHO and GAVI have labeled bird flu as a potential 'Disease X,' highlighting the need for vigilance and preparedness.
