CDC (official outbreak notice)
U.S. federal public-health agency
Background
The CDC traces its origins to the Office of Malaria Control in War Areas, established in 1942 to protect U.S. military training camps in the South. It became the Communicable Disease Center on July 1, 1946, headquartered in Atlanta, and gradually expanded to cover all communicable diseases. The agency was renamed Centers for Disease Control in 1980 and received its current name — Centers for Disease Control and Prevention — in 1992. For decades it operated as the nation's premier scientific public-health body, issuing epidemiological guidance, tracking outbreaks, and distributing Health Alert Network (HAN) notices to clinicians and health departments. The agency became politically controversial at times — notably during the 2020–2021 COVID-19 pandemic, when critics on both left and right questioned the consistency of its guidance. During the second Trump term beginning in 2025, the CDC has faced the most severe institutional pressures in its history: a proposed 53% budget reduction, termination of hundreds of grants, elimination of programs covering HIV prevention, global immunization, and chronic disease, and a steep decline in the number of HAN alerts issued — a pattern NPR and public-health researchers documented in early 2026. HHS has denied that the reduction in alerts reflects political muzzling. The CDC still issues outbreak notices for acute threats such as the 2026 Cyclospora/Taco Bell lettuce outbreak, the DRC Ebola outbreak, and measles clusters, but its overall communications capacity and independence are widely viewed as diminished compared to prior administrations.
