Bird flu, caused by the H5N1 avian influenza virus, is now spreading to cats and mice, raising concerns for public health. The virus was recently detected in 47 house mice in New Mexico and in domestic cats across multiple states. Historically, H5N1 cases in humans have been caused by close contact with infected birds, with a high fatality rate. The worry now is that the virus could mutate and spread easily between people, potentially sparking a global outbreak. The CDC recommends steps to minimize infection risk, and immediate treatment with antiviral medications for suspected cases. Symptoms include fever, cough, and respiratory illness.
