The US Centers for Disease Control and Prevention (CDC) has ended its emergency response to the H5N1 bird flu due to a significant decline in cases. No human cases have been reported since February 2025. Surveillance and readiness will continue under the CDC's influenza division. While the current public health risk is low, the CDC will monitor the situation and increase response efforts if necessary. The emergency response, declared in April 2024, provided additional support, including staffing, to address the widespread avian flu outbreak affecting millions of birds and mammals globally. Although cases have slowed, experts acknowledge seasonal fluctuations in bird flu activity.
