Avian flu was detected in a goose in Rock County, officials with the Rock County Public Health announced Monday. On Friday, the department got an alert from the Wisconsin Health Department that a goose tested positive for the avian flu, also known as bird flu. Officials stated the goose had been in contact with a Rock County resident. RCPH is working with DHS as well as the resident to monitor any symptoms and to prevent the spread of HPAI. Right now, that person has not reported any symptoms. There are no reported cases of bird flu transmitted to people in Rock County and the public health risk is low. The last confirmed case of HPAI was in 2022 through a chicken.

| Additional information | |
| Symptoms: | H5N1 is a type of influenza virus that causes a highly infectious, severe respiratory disease in birds called avian influenza (or "bird flu"). Human cases of H5N1 avian influenza occur occasionally, but it is difficult to transmit the infection from person to person. When people do become infected, the mortality rate is about 60%. Almost all cases of H5N1 infection in people have been associated with close contact with infected live or dead birds, or H5N1-contaminated environments. The virus does not infect humans easily, and spread from person to person appears to be unusual. There is no evidence that the disease can be spread to people through properly prepared and thoroughly cooked food. In most cases, avian influenza in humans develops into a serious disease that should be treated promptly in the hospital and may require intensive care, where available. The antiviral medicine oseltamivir can reduce the severity of illness and prevent death, and should be used in all cases. |
