CDC issues bird flu health alert to clinicians, state health departments, public after Texas farmer infected | 5 April 2024 | The Centers for Disease Control and Prevention (CDC) issued a health alert Friday to inform clinicians, state health departments and the public of a case of avian influenza in a person who had contact with dairy cows in Texas. A farmworker on a commercial dairy farm in Texas developed conjunctivitis last week, and subsequently tested positive for bird flu, the agency said. The positive bird flu diagnosis came after milk from dairy cows in Texas and Kansas tested positive for the disease. The infection follows a 2022 case in Colorado, and is the second person to test positive for the bird flu virus in the U.S.
