CSTE works to advance public health policy and epidemiologic capacity. We also provide information, education, and developmental support of practicing epidemiologists in a wide range of areas as well as expertise for program and surveillance efforts. CSTE is an organization of member states and territories representing public health epidemiologists. CSTE works to establish more effective relationships among state and other health agencies. It also provides technical advice and assistance to partner organizations and to federal public health agencies such as the Centers for Disease Control and Prevention (CDC). CSTE members have surveillance and epidemiology expertise in a broad range of areas including occupational health, infectious diseases, environmental health, chronic diseases, injury control, maternal and child health, and more. CSTE supports effective public health surveillance and good epidemiologic practice through training, capacity development, and peer consultation.
