À propos de ce contenu audio
Good afternoon. This is the Public Health Authority delivering today's H5N1 Bird Flu Briefing. Our purpose is to update you on the current situation, outline risks, and provide clear action steps to protect yourself and your community. While the virus remains widespread in wild birds, poultry, and U.S. dairy cows, the CDC assesses the public health risk to the general population as low. Since 2024, there have been 71 confirmed human cases in the U.S., mostly among dairy and poultry workers in states like California with 38 cases, mainly from dairy herd exposure. CDC reports no sustained human-to-human transmission, but we are monitoring closely with monthly surveillance data showing over 22,000 people tracked after animal exposure and only 64 cases detected.
This alert matters because H5N1 is highly contagious in animals, causing outbreaks in nearly 185 million birds since 2022 per USDA data, with recent detections in 67 U.S. flocks in the past 30 days. California's CDFA notes four dairies still under quarantine as of December 2025, down from hundreds, thanks to enhanced mitigation. While most human cases are mild, vigilance prevents escalation, as experts like those at the University of Glasgow warn the virus is out of control in wildlife globally.
Seek medical attention immediately if you experience severe symptoms after animal exposure: high fever over 103°F, difficulty breathing, chest pain, confusion, or persistent vomiting. These could indicate complications. Monitor at home milder signs like eye redness, cough, sore throat, muscle aches, headache, or fatigue for 10 days post-exposure, isolating if they worsen. CDC recommends antiviral treatment like oseltamivir for confirmed cases.
For poultry workers, dairy farm staff, and high-risk settings: Follow strict containment protocols. Wear PPE including N95 masks, goggles, gloves, and disposable coveralls. Practice biosecurity: disinfect equipment, limit farm visitors, quarantine sick animals, and report outbreaks to local agriculture departments. Avoid touching dead birds. CDC and USDA advise 10-day monitoring post-exposure.
General public guidelines by priority:
First, avoid direct contact with sick or dead wild birds, poultry, or dairy cows. Cook poultry and eggs to 165°F internal temperature.
Second, practice hand hygiene: wash with soap for 20 seconds or use sanitizer after outdoor activities.
Third, if you work with animals or live nearby, report unusual bird deaths to animal control.
Fourth, stay current on flu vaccines, as they offer partial protection.
For more information, visit cdc.gov/bird-flu or who.int for global updates. In emergencies, call 911 or your local health department hotline. Pasteurized milk and properly cooked products remain safe.
