Ghana has both a public and private healthcare system. The public system operates state hospitals while the private system has some hospitals adjacent to state facilities, such as the recognized Niaho Medical Center. Healthcare is covered by Ghana's Universal Healthcare system (NHIS) which uses a capitation system and could enable home doctor visits. Life expectancy is 66, infant mortality is 39 per 1000 live births, and fertility is 2.12 children per woman. Sanitation access is only 14% and HIV prevalence is 0.7%. There are some orphanages and sites run by volunteers from other countries to help children and older people.
