Bird Flu Bulletin: Daily H5N1 Update Saturday, September 27, 2025 Good afternoon. It’s Saturday, September 27, 2025, and you’re listening to the Bird Flu Bulletin, your daily update on the global H5N1 situation. I’m your host with Quiet Please. Top Stories First, the U.S. Department of Homeland Security Science and Technology Directorate has published a new report highlighting significant avian influenza activity around the globe. The H5N1 strain continues to spill over from wild and domestic birds into more mammals, with unprecedented outbreaks now impacting livestock such as dairy cattle and goats. International spillover has resulted in confirmed human cases in Mexico, Cambodia, the United Kingdom, Australia, and the United States. Of note, recent genetic analysis warns that the virus’s ability to recombine remains an ongoing global health security risk. Second, according to the Food and Agriculture Organization, the last 24 hours saw 249 official new outbreaks of high pathogenicity avian influenza across five regions. Of these, 139 were attributed specifically to H5N1. The United States, United Kingdom, and Spain recorded the highest totals, with new cases appearing in both commercial poultry and a wide list of wild birds. The expansion radius remains largest in the U.S., where nearly every state has reported affected populations. Third, new guidance issued by the Centers for Disease Control and Prevention stressed that, while human-to-human transmission of H5N1 has still not been observed, the recent increase in the number of mammalian species affected—including livestock—requires heightened biosurveillance and farm-level mitigation. Special advisories urge farm workers to use personal protective equipment and report suspected symptoms right away. Case Numbers Update Compared to yesterday, global confirmed human cases rose by 2, with new events verified in Europe and South America. The United States maintains a total of 70 human infections for the current year, most linked directly to dairy herd and poultry farm exposures. One death, recorded in Louisiana, remains the only U.S. fatality thus far. The number of new animal outbreaks worldwide, particularly in commercial poultry, is up 8 percent over the previous 24-hour period. Expert Interview Joining us for a brief perspective is Dr. Laura Kim, epidemiologist at the CDC’s Influenza Response Team: “The shift of H5N1 into mammals, especially cattle, represents a critical development. While no sustained human-to-human transmission is confirmed, vigilance is essential. We’re urging agricultural workers and veterinarians to prioritize personal protective measures, and for industry and state officials to rapidly report unusual symptoms in animals or staff.” Looking Ahead Tomorrow, world health authorities are expected to release updated recommendations regarding livestock testing protocols, particularly in dairy operations. The FAO will be hosting a regional risk briefing focusing on emerging hot spots in South America and Southern Europe, where migratory bird routes intersect with farming regions. U.S. health officials are planning to review their national stockpile of PPE for farm workers in high-risk states. Watch for new data releases from federal and international agencies, addressing risk mitigation and surveillance findings from the expanded outbreak zones.
