Nearly 1,300 probationary workers at the Centers for Disease Control and Prevention (CDC) were dismissed as part of a federal workforce reduction under U.S. President Donald Trump’s administration. This represents approximately one-tenth of the CDC's staff and is part of a broader restructuring effort across multiple government agencies. The downsizing is being overseen by Elon Musk and his team at the Department of Government Efficiency. The CDC, with a significant budget for state and local public health programs, is confronted with this reduction as the newly appointed Secretary of Health and Human Services, Robert F. Kennedy Jr., takes office.
