H5N1 Bird Flu Outbreak Spreads Across US Dairy Farms Raising Concerns for Farmworkers and Public Health

Bird Flu SOS: Urgent H5N1 News & Safety

About
This is Bird Flu SOS: Urgent H5N1 News & Safety, your emergency update on the fast-evolving avian influenza situation.

Today, we face an alarming development. According to the Centers for Disease Control and Prevention, the United States is experiencing widespread outbreaks of H5N1 bird flu, not only in wild and domestic birds, but now spreading further among dairy cattle across at least 17 states. The CDC confirms 70 human cases since April 2024, primarily among people working on affected poultry and dairy farms. Just this week, federal animal health officials reported new H5N1 infections in commercial poultry in seven states, and, of significant concern, additional detections in domestic cats and dairy cattle in California, Montana, and Oregon.

Dr. Anne Schuchat, former CDC principal deputy director, said in a recent briefing, “The route of H5N1 exposure in dairy cows is still not fully understood, but any spillover into mammals—and now repeated cases in farm workers—remind us that influenza viruses are unpredictable. Strict farm biosecurity and personal protection are more critical than ever.”

The CDC stresses that, at this moment, the risk to the U.S. general public remains low. However, the risk is moderate to high for those exposed directly to sick animals or contaminated environments on farms, in live markets, or where wild birds gather. One U.S. death has been reported in Louisiana after confirmed H5N1 infection.

If you live or work in an affected area, here’s what to do right now:
- Avoid direct contact with sick or dead birds, animals, or their droppings.
- Do not consume raw milk or unpasteurized dairy products, as viral RNA has been repeatedly detected in raw milk from infected cows.
- Wear gloves, masks, and protective eyewear when handling animals or cleaning pens, even if the animals appear healthy.
- If you develop any flu-like symptoms—especially after animal exposure—such as high fever, severe cough, sore throat, shortness of breath, or red, painful eyes, seek immediate medical attention and mention possible H5N1 contact.

Early warning signs requiring urgent care include trouble breathing, confusion, persistent pain or pressure in the chest, bluish lips or face, or sudden vision problems. These symptoms require immediate emergency response.

For assistance, contact your state or local health department or dial the CDC Emergency Operations Center at 770-488-7100 for urgent public health support. Visit the CDC’s Bird Flu Situation Summary webpage for regular updates and science-backed guidance.

Though the majority of Americans face low risk, communities near outbreaks and animal agriculture workers must stay alert. Dr. Demetre Daskalakis, director of CDC’s Influenza Division, emphasized, “This outbreak’s unpredictability means constant vigilance is key. Report any unusual animal deaths, and don’t hesitate to reach out for help.”
