Fourth Human Case of Bird Flu Confirmed Amid Dairy Cow Outbreak

The Centers for Disease Control and Prevention (CDC) confirmed a fourth human case of bird flu linked to an ongoing outbreak among dairy cows, this time involving a dairy worker in Colorado. The individual, who had contact with cows infected with the H5N1 strain of avian influenza, reported symptoms and was under monitoring due to their exposure. Initial state-level tests were inconclusive, but further testing by the CDC confirmed the presence of influenza A. The patient, who experienced only eye symptoms, has since recovered after receiving antiviral treatment. Prior to this case, three other human infections were reported: one in Texas and two in Michigan, all involving dairy farm workers. The CDC has reassured the public that the risk of widespread transmission remains low, advising individuals to avoid close contact with sick or deceased animals and to steer clear of unpasteurized dairy products or animal waste from potentially infected animals. In response to the outbreak, federal and state health officials have been investigating illnesses in older dairy cows across Kansas, New Mexico, and Texas, which have shown symptoms like decreased milk production and low appetite. The USDA has stated that there is no threat to the safety of the commercial milk supply, emphasizing that pasteurization processes eliminate any potential risk. As a precautionary measure, the CDC is preparing for a possible increase in human health risks associated with bird flu, including bolstering the national vaccine stockpile to ensure readiness in the event of further outbreaks.
