CDC is a federal public health agency headquartered in Atlanta, Georgia that conducts disease prevention, health promotion, and health protection activities across the United States and internationally. It was established in 1946 and has evolved into a major center for epidemiology, laboratory science, and emergency response, engaging with partners such as the World Health Organization, Pan American Health Organization, National Institutes of Health, Food and Drug Administration, and state health departments. The agency operates programs spanning immunization, infectious diseases, chronic disease, occupational health, and injury prevention while coordinating responses to outbreaks like H1N1 influenza pandemic, Ebola virus epidemic in West Africa, and the COVID-19 pandemic.

History

The agency traces its origins to the Malaria Control in War Areas program created in 1942 in response to vector-borne disease threats during World War II and formally became the Communicable Disease Center in 1946. Early work involved malaria control in the Southeastern United States and collaborations with the United States Public Health Service and the National Foundation for Infantile Paralysis. During the mid-20th century the center expanded into smallpox surveillance linked to the Smallpox eradication campaign and polio vaccine monitoring following the development of the Salk vaccine and the Sabin vaccine. In later decades the organization adapted to emerging challenges including the HIV/AIDS epidemic, the outbreak investigations of legionellosis at the American Legion convention in Philadelphia (Legionnaires' disease), and biodefense concerns following the 2001 anthrax attacks.

Organization and Governance

The agency is an operating component of the United States Department of Health and Human Services and is led by a Director who reports to the Secretary of Health and Human Services. Internal divisions include centers, institutes, and offices such as the National Center for Immunization and Respiratory Diseases, the National Center for Emerging and Zoonotic Infectious Diseases, and the Agency for Toxic Substances and Disease Registry cooperative efforts. Governance involves advisory committees including the Advisory Committee on Immunization Practices, the Board of Scientific Counselors, and interagency coordination with entities like the Federal Emergency Management Agency, the Centers for Medicare & Medicaid Services, and the Office of the Surgeon General.

Functions and Programs

The agency conducts vaccination policy via the Advisory Committee on Immunization Practices and supports programs such as the Vaccines for Children Program and the Global Polio Eradication Initiative partnership. It administers surveillance systems including the National Notifiable Diseases Surveillance System and programs targeting chronic conditions linked to initiatives like the Behavioral Risk Factor Surveillance System. Occupational and environmental health work engages with the National Institute for Occupational Safety and Health and monitors exposures under the Toxic Substances Control Act context. Injury prevention programs collaborate with the National Highway Traffic Safety Administration and the Consumer Product Safety Commission on falls, motor vehicle safety, and household hazards. International technical assistance includes cooperation with the President's Emergency Plan for AIDS Relief and mission support during humanitarian crises led by the United Nations and regional partners.

Research and Surveillance

The agency operates high-containment laboratories such as Biosafety level 4 facilities and maintains surveillance through sentinel networks like the Influenza Surveillance Network and molecular surveillance platforms including genomic sequencing collaborations with the Global Initiative on Sharing All Influenza Data. Research priorities encompass vaccine effectiveness studies in partnership with the National Institutes of Health, antimicrobial resistance tracking via the Antibiotic Resistance Lab Network, and social determinants research linked to programs by the Robert Wood Johnson Foundation. Field epidemiology training is provided through the Epidemic Intelligence Service, which has responded to outbreaks including West Nile virus introductions and foodborne illness outbreaks traced through collaborations with the United States Department of Agriculture and the Food Safety and Inspection Service.

Public Health Response and Emergency Preparedness

The agency’s emergency operations model activates incident management structures during crises such as the H1N1 influenza pandemic, the Ebola virus epidemic in West Africa, and the COVID-19 pandemic. It issues guidance on nonpharmaceutical interventions and medical countermeasures, coordinating with the Strategic National Stockpile and international bodies including the World Health Organization. Preparedness programs encompass exercises with the Department of Defense, laboratory surge capacity, and continuity planning with state and local health departments, as seen during hurricane responses with the Federal Emergency Management Agency and mass gathering surveillance at events like the Olympic Games.

Criticism and Controversies

The agency has faced scrutiny over handling of events including communication and policy during the COVID-19 pandemic, debates about masking and testing guidance, and the timeliness of travel advisories during the Ebola virus epidemic in West Africa. Past controversies include laboratory safety incidents that prompted reviews of policies for high-containment facilities and questions raised during the response to the HIV/AIDS epidemic about early public messaging. Oversight and investigations by the United States Congress and audits from the Government Accountability Office have led to reforms in transparency, data reporting, and interagency coordination.
