ABSTRACT
The study of the health care industry. The industry has a large range of products both in the form of
public health and personal health care. Public health measures include health education, which will reduce later the demand for health care, and protection of the public against epidemics and contamination from poor quality food and unsafe working conditions. Governments also have an important role in licensing health professionals and drugs. Personal health care consists of all those interventions, whether surgical, medical or therapeutic, chosen to deal with a particular disease, injury or other debilitating condition. Health systems differ from country to country according to the structure of production. There can be state-provided hospitals and clinics, facilities offered by commercial firms or charities. It is usual for there to be a mixture of ownership. All these types of provider will operate according to different principles, whether meeting need as decided by government with state medicine, making a profit through private production, or furthering a welfare goal set by a charity either concerned generally with helping the sick or dealing with a particular type of medical problem.
