"CDC [Centers for Disease Control and Prevention] provides technical assistance and resources to state and local public health agencies to support their efforts to build prepared and resilient communities. CDC provides subject-matter expertise and assistance for domestic and global surveillance, laboratory, occupational health and epidemiology functions, and health threats including anthrax, smallpox, influenza and other infectious diseases, food-borne illness, and radiation, among others. CDC's Office of Public Health Preparedness and Response (OPHPR) leads the agency's preparedness and response activities by providing strategic direction, support, and coordination for activities across CDC as well as with local, state, tribal, national, territorial, and international public health partners. In the decade since September 11th and the anthrax attacks, significant investments have been made in the nation's public health system to respond to all-hazard threats. Public health departments at all levels of government can now quickly staff public health emergency operations centers; there is improved proficiency in laboratories testing for biological and chemical agents across the nation and the globe; and states can receive urgent disease reports and rapidly communicate information about health threats and related preventive and protective actions to the public."
