The public health system is a set of government-run programs that aim to provide access to clean drinking water, basic sewage and sanitation services, and inoculation against infectious diseases. This system is not the same as the health care system, which refers to medical services individuals receive when they are sick or injured. The welfare system, including the government welfare system, provides financial assistance to those in need, but it is not directly related to public health programs.
