Principal Deputy DirectorAnne Schuchat


On July 1, 1946, the Communicable Disease Center opened its doors in Atlanta, GA, with the goal of stopping the spread of malaria nationwide. With a budget of $10 million, its employees numbered fewer than 400. Shovels, sprayers, and trucks were among the most important tools for slowing the disease's spread.

The Centers for Disease Control and Prevention (CDC), as part of the Public Health Service, protects the public health of Americans by leading the national effort to prevent and manage diseases and other preventable conditions and by responding to public health emergencies. Within the CDC, the following five directorates lead efforts to diagnose, prevent, and treat public health hazards.

Infectious Diseases Research and Policies

The CDC oversees three infectious disease national centers. The National Center for Emerging and Zoonotic Infectious Diseases focuses on diseases that have been known for many years, emerging diseases, and zoonotic diseases (i.e., those that spread from animals to people). The National Center for HIV/AIDS, Viral Hepatitis, STD and TB Prevention eliminates, prevents, and controls disease, disability, and death caused by human immunodeficiency virus infection/acquired immunodeficiency syndrome, non-HIV retroviruses, viral hepatitis, other sexually transmitted diseases, and tuberculosis. The National Center for Immunization and Respiratory Diseases mitigates the effects of disease, which include disability and death, through immunization and by controlling respiratory and related diseases.

Occupational Safety and Health

The National Institute for Occupational Safety and Health conducts research to reduce worker illness and injury and to advance worker well-being; promotes safe and healthy workers through interventions, recommendations, and building capacity to address hazards; and enhances worker safety and health through collaborations that are global in scope.

Noncommunicable Diseases Prevention

The CDC's current noninfectious disease priorities include marijuana use outcomes that affect health, mental health, and the prevention of nonoccupational hearing loss. Its noninfectious disease services are provided by four national centers: the National Center on Birth Defects and Developmental Disabilities; the National Center for Chronic Disease Prevention and Health Promotion; the National Center for Environmental Health / Agency for Toxic Substances and Disease Registry; and the National Center for Injury Prevention and Control.

Public Health Preparedness and Response

The Center for Preparedness and Response helps the Nation prepare for and respond to urgent public health threats by providing strategic direction, coordination, and support for CDC's terrorism preparedness and emergency response activities.

Public Health Science and Surveillance

The Public Health Science and Surveillance services—which include the National Center for Health Statistics and the Center for Surveillance, Epidemiology, and Laboratory Services (CSELS)—lead the effort in promoting and facilitating science, surveillance, standards, and policies for reducing the burden of diseases in the United States and abroad. The CSELS promotes collaboration among health professionals globally; supports educational, training, and professional opportunities in epidemiology and public health science; maintains datasets and manages and preserves specimens; facilitates the sharing of health information; and reports on emerging public health problems. Within the CDC, the Office of Laboratory Science and Safety oversees and coordinates critical laboratory policies and operations; the Office of Science serves as the CDC’s authority on scientific quality, integrity, and innovation.

Public Health Service and Implementation Science

One office and three centers lead the national effort to promote and facilitate science programs and policies for identifying and responding to domestic and global public health threats. These four components are the Center for Global Health; Center for Preparedness and Response; Center for State, Tribal, Local and Territorial Support; and the Office of Minority Health and Health Equity.
