Announcement: CDC's 70th Anniversary.

July 1, 2016, marks the 70th anniversary of the establishment of CDC. Since the agency's launch as the Communicable Disease Center on July 1, 1946, CDC's primary mission has been improving public health in the United States and around the world through prevention and preparedness. In the seven decades since CDC's founding, the agency has grown in size and mission and is recognized as the nation's premiere health promotion, disease prevention, and emergency preparedness agency, and a global leader in public health. CDC's mission has progressed beyond communicable disease control and now encompasses noninfectious diseases, injury prevention, and environmental and occupational health.
