The Colorado Department of Public Health and Environment reported three new human cases of bird flu among poultry farm workers, raising the total number of confirmed cases in the US this year to 13. The affected workers, who were culling infected chickens at a Weld County egg farm, are experiencing mild symptoms and have been offered antiviral medication. The bird flu outbreak has spread to poultry in nearly every US state since early 2022 and has also impacted dairy cattle. While the CDC indicates that the risk to the general public remains low, it advises farm workers to use personal protective equipment. A CDC field team is currently in Colorado to assist with the outbreak response.
