First Human H5N5 Bird Flu Death Confirmed in Washington State as US Cases Rise to 71

Bird Flu Bulletin Daily H5N1 Update Monday, November 24, 2025 Good afternoon. This is Bird Flu Bulletin Daily H5N1 Update. Today is Monday, November 24, 2025. Here are the top stories. Top Stories One, health authorities in Washington state confirmed the world’s first human death from the H5N5 strain of bird flu. The patient was an older adult with underlying health issues who contracted the virus from a backyard flock. Washington State Department of Health reports no evidence of human-to-human transmission and the public risk remains low. Two, the Centers for Disease Control and Prevention updated its bird flu situation summary. H5N1 human cases in the United States now stand at 71, up by one from yesterday, following targeted surveillance and active monitoring of exposed individuals. The additional case involved occupational exposure at a poultry facility. The vast majority of cases remain mild, often presenting as conjunctivitis, headache, or mild respiratory symptoms, with severe disease primarily observed in older adults with health conditions. Three, authorities are urging continued use of protective equipment for workers exposed to sick animals. Recommended measures include using NIOSH-approved respirators, fluid-resistant coveralls, goggles, boots, head cover, and disposable gloves. The CDC maintains that the overall public health risk is low, but emphasizes vigilance given the ongoing panzootic among animals. Case Numbers Compared to Yesterday Human case totals increased by one in the last 24 hours, now at 71. This case was linked to direct animal exposure on a poultry operation. The CDC notes most cases continue to be detected through active surveillance of exposed workers. Guidance from Health Authorities The CDC reiterates no evidence of sustained human-to-human transmission of either H5N1 or H5N5 strains. The use of personal protective equipment is strongly recommended for anyone working in close contact with infected birds or mammals. Health departments are advised to expedite testing and reporting for suspected cases, especially among vulnerable populations. Expert Interview Snippet Dr. Megan Porter, epidemiologist with the CDC, explains: “While the rise in detected cases reflects effective surveillance, the risk to the average American remains very low. However, individuals working with poultry or dairy herds should adhere strictly to PPE guidelines. Early detection in exposed communities is the key to preventing wider spread. We are actively monitoring for any genetic changes that could increase transmission.” Looking Ahead Tomorrow, public health officials expect the latest monthly update from national flu surveillance, which may revise cumulative numbers for both human H5N1 and H5N5 cases. Increased scrutiny of backyard poultry operations and continued monitoring of occupational exposure sites are anticipated. If any significant genetic change is detected in the circulating virus, further guidance will be promptly This content was created in partnership and with the help of Artificial Intelligence AI.
