Bird Flu SOS: Urgent H5N1 News & Safety

[Host, urgent but steady tone] Welcome to Bird Flu SOS: Urgent H5N1 News & Safety. I'm your host, and today we have a critical update on a deadly development: the first-ever confirmed human case of influenza A(H5N5) in the United States, reported by the World Health Organization on November 15, 2025. This patient in Washington State, with underlying conditions, died on November 21 after severe illness, marking the 71st H5 human case in the US since early 2024 and the first since February. WHO confirms no human-to-human transmission, but the virus from clade 2.3.4.4b has been in wild birds and mammals since 2023.

The situation is escalating fast. CDC reports H5N1 widespread in wild birds, poultry outbreaks hitting 70 US flocks in the past 30 days with 820,000 birds affected, and nearly 1,000 dairy farms in 17 states impacted. In Europe, EFSA notes 442 poultry outbreaks and 2,454 in wild birds from September to November 2025 alone, with new cases in cats and carnivores. USDA confirmed a fresh H5N1 spillover in a Wisconsin dairy herd on December 14, genotype D1.1, separate from prior events.

Experts are sounding the alarm responsibly. Dr. Jeremy Rossman of the University of Kent warns, "Without strategic and coordinated surveillance and containment, the risks of a human transmissible H5N1 virus will steadily rise." CDC emphasizes the public health risk remains low, but they're monitoring over 30,100 exposed people since March 2024, with 1,260 tested. Virologist Dr. Kaitlyn Hutchinson notes, "You now have a situation where a large proportion of consumer milk in the US contains genetic material from these highly pathogenic viruses."

If you're in affected areas like dairy states or near poultry farms, take immediate action: Avoid contact with sick or dead birds, wild mammals, or unpasteurized milk. Wash hands thoroughly after animal exposure. Farmers: House poultry indoors, enforce strict biosecurity per EFSA guidelines. Cook poultry and eggs to 165°F; pasteurization kills the virus in milk, per USDA—no risk to commercial supply.

Warning signs demanding emergency response: Fever, cough, shortness of breath, eye redness, or conjunctivitis after animal contact. Seek medical care immediately—tell providers about exposures. CDC surveillance has tested over 223,000 specimens, detecting just 7 H5 cases nationally.

For help: Call CDC at 1-800-232-4636 or visit cdc.gov/bird-flu. State health departments offer exposure monitoring. Stay informed via WHO and USDA updates.

This is serious, but preparedness protects us. No need for panic—action saves lives.
