Bird Flu Monitoring Continues: Low Human Risk but Ongoing Surveillance in US Dairy Herds and Poultry Flocks

Bird Flu Bulletin: Daily H5N1 Update Monday, December 8, 2025 This is your three-minute Bird Flu Bulletin, bringing you the latest on H5N1 and related avian flu threats around the world. Top stories in the last 24 hours: First, in the United States, monitoring of people exposed to infected birds, poultry, and dairy cows continues at high volume. According to the U.S. Centers for Disease Control and Prevention, at least 30,600 people have now been monitored and at least 1,280 tested for novel influenza A viruses since March 2024, with no indicators of unusual flu activity in the general population and no evidence of ongoing human-to-human spread. Second, the World Health Organization has confirmed follow-up findings on the recent fatal human case of avian influenza A(H5N5) in Washington State, the first human H5N5 case ever reported globally and the 71st human A(H5) case in the United States since early 2024. WHO reports that all identified contacts have been monitored and no additional human cases or human-to-human transmission have been detected so far. Third, animal health authorities in several U.S. states and across Europe continue to report detections of highly pathogenic avian influenza in wild birds and poultry flocks. Agencies including the U.S. Department of Agriculture stress that the virus remains widespread in birds, keeping the risk of spillover to people who work closely with infected animals an active concern. Case numbers compared to yesterday: Global and U.S. human case counts have not changed in the last 24 hours. Through May 2025, a peer‑reviewed analysis in a U.S. medical journal documented 70 human H5N1 cases in the United States, mostly mild and linked to dairy cows and poultry, with four hospitalizations and one death, and no confirmed human-to-human transmission. The recent Washington State H5N5 death, reported by WHO in November 2025, brings total U.S. human A(H5) infections to 71 since early 2024, with no new cases added today. New guidance and statements: The CDC continues to state that the risk to the general public in the United States is low, but advises people who work with poultry, wild birds, or dairy cattle to use personal protective equipment, avoid direct contact with sick or dead animals, and report any flu-like symptoms after exposure. State animal health agencies, such as Clemson University’s animal health program in South Carolina, are urging backyard flock owners to tighten biosecurity during peak bird migration, including keeping domestic birds away from wild waterfowl and promptly reporting unexplained illness or deaths in birds. Interview snippet: Joining us briefly is Dr. Maria Lopez, an infectious disease specialist working with avian influenza surveillance. Host: “Dr. Lopez, what is the single most important message for listeners today?” Dr. Lopez: “The key point is that while H5 viruses remain a serious threat in birds, human infections are still rare and pri This content was created in partnership and with the help of Artificial Intelligence AI.
