The Oklahoma State Department of Health, through its system of local health services delivery, is ultimately responsible for protecting and improving the public's health status through strategies that focus on preventing disease. Four major service branches, Community and Family Health Services, Wellness Programs, Disease, Prevention and Preparedness Services and Protective Health Services, provide technical support and guidance to 68 county health departments as well as guidance and consultation to the two independent city-county health departments in Oklahoma City and Tulsa.
