Cdc

The Centers for Disease Control and Prevention (CDC) is a U.S. federal health agency operating under the Department of Health and Human Services. Established in 1946, the CDC serves as the primary federal agency responsible for protecting public health and safety through disease prevention, health promotion, and emergency response. The agency conducts research, provides scientific guidance, and coordinates responses to health threats ranging from infectious disease outbreaks to chronic disease prevention.

Climate Change and Health

The CDC produces educational and scientific content addressing the health impacts of climate change on communities and vulnerable populations. This work includes research and public guidance on how climate-related environmental changes—such as rising temperatures, extreme weather events, and shifting disease vectors—affect human health. The agency identifies populations at heightened risk, including low-income communities, older adults, and those with existing health conditions, and develops resources to support adaptation and resilience.

Core Functions

Beyond climate-related health work, the CDC maintains broad responsibilities in epidemiology, surveillance systems, laboratory services, and emergency preparedness. The agency works with state and local health departments, international partners, and other federal agencies to monitor disease trends, investigate outbreaks, and implement prevention strategies across the United States.
