H5N1 Bird Flu Cases Decline Nationwide as CDC Shifts to Monthly Reporting and Maintains Low Alert Level

This is Bird Flu Bulletin: Daily H5N1 Update. Today is Wednesday, July 9, 2025. Top stories First, the U.S. Centers for Disease Control and Prevention has further reduced its bird flu alert level. As of this week, there have been no indicators of unusual flu activity in people, including avian influenza H5N1, and recent human infections remain very low. The CDC shifted to monthly reporting on bird flu cases and surveillance, reflecting the currently low public health threat in the United States. Second, World Health Organization data show that globally, H5N1 continues to circulate primarily in poultry and wild birds, with sporadic human cases linked to direct contact with infected animals or contaminated environments. Cambodia recently reported new human infections in children following exposure to sick poultry. The WHO continues to stress the potential severity of infection but reiterates that the overall public health risk remains low for the general population. Third, on the animal front, U.S. Department of Agriculture surveillance indicates that while H5N1 outbreaks persist in poultry and dairy cattle, the number of new animal detections has declined over the last month. Monitoring continues, but no new significant animal outbreaks have been reported in the last 24 hours. Case Numbers Compared to yesterday, there have been no newly confirmed human H5N1 cases reported in the United States. The total since February 2024 stands at 70 human infections and one related fatality. Globally, WHO records indicate the total number of confirmed cases since 2003 has reached 986, with no significant changes in the last day. Most recent global cases continue to be isolated incidents linked to animal exposure. Health Guidance In a statement yesterday, the CDC confirmed that routine influenza monitoring will now include H5N1 surveillance, with national updates issued monthly rather than weekly. The CDC and WHO both advise that the risk to the general public remains low, though occupational exposure risks persist for farmworkers and others in close contact with poultry or cattle. Current seasonal flu vaccines do not protect against H5N1, but vaccines specific to H5 are approved in some countries. No such vaccines have been deployed in the U.S. during the current outbreak. Expert Interview For more insight, we spoke briefly with Dr. Angela Ruiz, an infectious disease specialist at the University of Minnesota. She says, “While we’re seeing a reassuring slowdown in both human and animal H5N1 cases, vigilance is still key. Continued monitoring, rapid reporting of suspect cases, and vaccination campaigns for occupational groups will help keep the risk low, even as the virus remains active in birds and some mammals.” Looking Ahead Tomorrow, health authorities are expected to maintain the current low-alert level. Monthly surveillance updates are anticipated later this week from both the CDC and the World Health Organization.
