 An extensive network of public clinics offers basic care at low cost, and general and specialist hospitals operated by the Ministry of Health provide higher levels of care.In most large cities, well-to-do persons use private clinics and hospitals that charge high fees.Specialised medical facilities are concentrated in urban areas, but rural communities have relatively good access to primary care physicians at clinics in villages, where the government-sponsored primary health care system has raised the level of health education and prenatal care since the late 1990s.
