The Centers for Disease Control and Prevention has formally ended its emergency response to the H5N1 bird flu outbreak, marking a significant shift after over a year of heightened vigilance. According to the CDC, the drop in both human and animal infections prompted this change. Regular monitoring and surveillance will continue, but on a more routine basis, now merging H5N1 updates with their usual flu reporting systems. Weekly emergency briefings and animal infection trackers have been retired in favor of monthly updates, reflecting a notable decline in cases nationwide.
Let’s turn to the numbers. Since the first US cow infections were identified in March 2024, there have been 70 human cases of highly pathogenic avian influenza reported in the United States, all linked to direct exposure to infected animals. Most recent data from USDA and CDC confirm no new human cases in July, with the last significant animal outbreak in late June involving a dairy herd in Arizona. Since early June, only three new poultry outbreaks have been confirmed, affecting about 30,000 birds in Arizona, Idaho, and Pennsylvania. For context, the spring wave saw millions of birds culled to contain larger outbreaks, particularly in the Southwest.
In terms of official guidance, the CDC now recommends clinicians remain alert for flu-like symptoms and conjunctivitis in patients with recent animal exposure, especially farm workers. While risk to the general US public remains low, ongoing surveillance is emphasized. Farmers are encouraged to keep up biosecurity measures, as experts warn the virus could resurge with returning migratory birds in the fall.
Some health professionals have voiced concern about scaling back reporting. As reported by Farm Policy News, infectious disease specialists caution that reduced public attention could allow the virus to mutate unnoticed, emphasizing the importance of continued vigilance among agricultural workers and health officials.
Research continues on H5N1’s behavior in mammals. Recent studies confirm that human-to-human transmission remains extremely rare, but the virus’s ability to jump species remains under close scrutiny. There are currently no approved vaccines for H5N1 in humans, so preventing exposure remains the primary public health tool.
What does this mean for you? For most Americans, the risk remains minimal. Those working with poultry or dairy cattle should use protective gear and report any symptoms promptly. There is no evidence that properly pasteurized milk or cooked poultry transmits H5N1.
Comparing to previous weeks, the situation has calmed considerably, with fewer outbreaks and the CDC stepping down from emergency mode. Still, experts remind us that the virus is far from eradicated, with continued low-level circulation among wild birds and farm animals expected.
