A health department administers public health services by encouraging healthy practices. It works to ensure that health care is safe, affordable, effective, and accessible to everyone. The health department helps create and implement local and regional health care policies and works to improve the quality of existing services through promoting modern medical technologies. A health department is funded by state and federal funds, Medicaid, private grants, fees, and various contractual revenues.
Health departments oversee prenatal and perinatal care, family planning, health assessment, prevention, and treatment. They are also responsible for immunizations and the control of communicable diseases, hygiene, medical check-ups, cancer prevention, epidemic monitoring, disaster preparedness, and protection from environmental hazards. They also help enforce health policies, identify community health issues, and research cost-effective solutions to existing health problems.
