The Centers for Disease Control and Prevention (CDC) has confirmed the first severe case of H5N1 bird flu in the U.S., showing mutations that have prompted warnings from experts about the potential for another pandemic. The case involves a 65-year-old man from Louisiana who had contact with sick backyard birds. Genetic analysis revealed mutations in the virus's hemagglutinin (HA) gene, which could enhance its ability to infect humans. Dr. Dean Blumberg, an infectious disease expert, warned that the virus may mutate to become more easily transmitted from person to person. Dr. Deborah Birx, former White House Coronavirus Response Coordinator, criticized the CDC for insufficient testing, noting that only 530 tests have been conducted out of over 10,000 exposures monitored. She emphasized the need for increased testing, especially among dairy farm workers, to prevent co-infection with seasonal flu that could lead to further mutations. Additionally, Dr. Leana Wen has called for immediate FDA authorization of H5N1 vaccines, with the Biden Administration having already contracted for nearly 5 million doses.
