In 2011, the General Assembly restored DPH to its own state agency after more than 30 years of consolidation with other departments. At the state level, DPH functions through numerous divisions, sections, programs and offices. Locally, DPH funds and collaborates with Georgia's 159 county health departments and 18 public health districts. Through the changes, the mission has remained constant – to protect the lives of all Georgians. Today, DPH’s main functions include: Health Promotion and Disease Prevention, Maternal and Child Health, Infectious Disease and Immunization, Environmental Health, Epidemiology, Emergency Preparedness and Response, Emergency Medical Services, Pharmacy, Nursing, Volunteer Health Care, the Office of Health Equity, Vital Records, and the State Public Health Laboratory.
