Health officials confirm the infection as a rare 'one-off' case with no known links to ongoing outbreaks.

Dairy farms in Wisconsin, like this one in Dodge County, have not be affected by bird flu, though several dairy cows in neighboring Michigan have been diagnosed in the last month, according to federal data, and Minnesota and Iowa had cases earlier in the summer.
Scientists say they are concerned that the bird flu virus infecting dairy cows and poultry flocks in the US will have opportunities to become a more dangerous virus over the fall and winter.

Overview

  • A Missouri resident was hospitalized on August 22 with symptoms including chest pain, nausea, vomiting, and diarrhea.
  • The CDC has not identified how the patient contracted the bird flu, making it the 14th human case in the U.S. this year.
  • Previous U.S. cases were among farm workers linked to outbreaks on poultry and dairy farms, but this case has no known animal contact.
  • The patient has since recovered and returned home after receiving antiviral treatment.
  • The CDC plans to vaccinate farm workers against seasonal flu in October to prevent co-infection and potential virus mutations.
