U.S. Department of Health and Human Services

The U.S. Department of Health and Human Services is the principal federal agency tasked with protecting the health of all Americans and delivering essential human services. It oversees a broad portfolio of operating divisions that include the Centers for Disease Control and Prevention, the Food and Drug Administration, the National Institutes of Health, and the Centers for Medicare & Medicaid Services. Through these components the department administers major programs such as Medicare, Medicaid, and the Children’s Health Insurance Program, while also coordinating nationwide efforts in disease prevention, food safety, medical research, and social service provision. Its mandate extends to preparing for and responding to public health emergencies, ensuring that the nation’s health infrastructure remains resilient during crises.

Headquartered in Washington, D.C., the department operates across the entire United States, serving every state and territory. Its activities touch the lives of millions of individuals who depend on its services for health coverage, access to safe medications, and protection against infectious diseases. The agency employs a substantial civilian workforce that supports its diverse missions, ranging from regulatory inspections to grant‑funded research initiatives. Because of its nationwide scope, the department’s policies and actions have a direct impact on public health outcomes and economic stability throughout the country.

A distinguishing attribute of HHS is its regulatory authority over food, drugs, medical devices, and biologics, which enables it to set and enforce safety standards that protect consumers. The department also leads the nation’s public health preparedness and response, as demonstrated during the COVID‑19 pandemic when it coordinated testing, vaccination, and guidance efforts. In addition, it manages the largest health insurance programs in the United States, providing coverage to seniors, low‑income families, and children. Its role in advancing biomedical research through the NIH fosters innovation that drives new treatments and cures. Cybersecurity is another area of focus, highlighted by incidents in 2020 and 2023 where attackers exploited third‑party MOVEit Transfer software and attempted to overload departmental servers, underscoring the importance of safeguarding health‑related data against supply‑chain threats.

Structurally, the U.S. Department of Health and Human Services is a cabinet‑level department of the Executive Branch of the federal government, headed by the Secretary of Health and Human Services who reports directly to the President. It comprises numerous operating and staff divisions that function under its authority, and it does not have a parent corporation or private owners; it is a sovereign government entity. This placement within the executive branch allows the department to implement national health policies and execute programs that align with the administration’s priorities while maintaining accountability to Congress and the public.
