Six Human Cases of Bird Flu Reported in US: Michigan and Colorado Poultry Workers Infected as Avian Flu Spreads to Mammals

In recent developments, the Centers for Disease Control and Prevention (CDC) reported six human cases of bird flu in the United States, with five cases identified in poultry workers from Michigan and Colorado. The latest case was reported from an additional worker at a poultry farm in Colorado. The CDC field team is assisting with the investigation, while the US Department of Agriculture (USDA) reports a growing number of infected cattle across multiple states.

The H5 highly pathogenic avian flu virus has affected over 18.32 million birds from commercial flocks and backyard flocks since April. The current strain is closely related to the first human case identified in Michigan, with no signs of antiviral resistance. All infected workers have experienced mild symptoms, including pink eye and respiratory issues, and have been offered antiviral medication.

Four poultry workers in Colorado contracted the virus through their work culling birds to control the spread of disease. The CDC advises that everyone avoid close or long exposure to sick or dead animals, animal poop or bedding. Poultry products are still safe to eat if they have been properly handled and cooked.

The Michigan Department of Health and Human Services launched a study on asymptomatic infections but found no evidence of such cases. The threat to the general public remains low, as the virus has not spread between people.

Bird flu has been spreading among mammals, including dairy cows and poultry, since 2020. Climate change is contributing to this dangerous combination by creating conditions that allow these diseases to thrive. The CDC continues to monitor the situation closely.

  • Fallacies (85%)
    The article does a good job of reporting on the H5N1 outbreak without making any logical fallacies. It provides clear and direct information about the locations of the outbreaks, actions being taken by authorities, and relevant statistics. However, it does not provide enough context or evidence to support some of its claims (such as a surge in KP.3.1.1 detections leading to it becoming dominant) which could lead to an overstatement of the situation.
    • As Colorado continue its response to a highly pathogenic H5N1 avian flu outbreak at a massive egg-laying farm connected to five H5 illnesses in people working as poultry cullers, federal agriculture officials confirmed another outbreak at a large layer farm that houses 1.3 million birds.
