Primary health care can provide 90 percent of health services a person will need throughout their life and is an important foundation for USAID’s Global Health investments. Primary health care promotes health awareness through disease prevention, diagnosis, and treatment. Most of the reproductive, maternal, newborn, and child health services, along with key communicable and noncommunicable disease interventions, are delivered as components of primary health care. It advances USAID’s mission to reduce inequities in life expectancy by increasing access to essential health services and bolstering national security against infectious disease threats.
