Four Colorado poultry workers have been diagnosed with bird flu, bringing the total number of U.S. cases to nine since 2022.
Mike Stobbe reports for The Associated Press.
In short:
- The infected workers experienced mild symptoms, including respiratory issues and irritated eyes, and none were hospitalized.
- A fifth worker with symptoms is currently being tested for the virus.
- The virus, H5N1, has been spreading among various mammals and was detected in U.S. livestock earlier this year.
Why this matters:
The spread of bird flu among both animals and humans raises concerns about potential future mutations that could increase transmissibility and severity, making ongoing monitoring and preventive measures critical.
