The Centers for Disease Control and Prevention (CDC) has identified a second human case of bird flu linked to the ongoing outbreak on U.S. dairy farms. Both cases involved dairy workers exposed to cows infected with the H5N1 avian influenza strain, which has been detected in cattle in nine states. While raw milk from infected cows has tested positive for the virus, no human infections have been linked to consuming it. The CDC maintains that the risk to the general public remains low, but recommends avoiding close contact with sick or dead animals, their waste, or unpasteurized milk from infected sources.
