From 2003 to 2023, bird flu, specifically H5N1, was a significant concern with high mortality rates. However, 2024 saw the U.S. emerge as the epicenter for human infections. Surprisingly, the severity of these newer cases has decreased drastically. Despite a spike in infections linked to new reservoirs in dairy cows, the majority of reported cases were mild. Health officials warn that while current outcomes seem favorable, early conclusions about the virus's risk may be misleading, especially for vulnerable populations.
