The key elements of PHC include health education on prevailing health problems and methods of preventing and controlling them, nutrition and an adequate supply of safe water and basic sanitation, maternal and child health care including family planning, immunization against major infectious diseases, appropriate treatment of common diseases and injuries, and the provision of essential drugs.
