C's for Disease Control and Prevention (CDC) an agency of the United States Department of Health and Human Services whose headquarters is in Atlanta, Georgia. It is concerned with all phases of control of communicable, vector-borne, and occupational diseases and with the prevention of disease, injury, and disability. Its responsibilities include epidemiology, surveillance, detection, laboratory science, ecological investigations, training, disease control methods, chronic disease prevention, health promotion, and injury prevention and control. Its major tasks include the licensing of qualified clinical laboratories for interstate commerce, maintenance of laboratories as reference centers for microorganisms and infectious diseases, and operation of extensive research programs in the prevention, detection and control of disease. The CDC's name has changed several times to reflect its expanding role; it has been called the Communicable Disease Center (1946), the Center for Disease Control (1970), and the Centers for Disease Control (1980). The latest name change, enacted by Congress in 1992, reflects the expansion of the scope of the CDC's mission to include health promotion and education. Because of the widespread recognition of the acronym CDC, that acronym continues to be used by the agency. The mailing address of the CDC is Centers for Disease Control and Prevention, 1600 Clifton Rd. NE, Atlanta, GA 30333, and the website is http://www.cdc.gov.
