Health care, or healthcare, refers to the treatment and management of illness, and the preservation of health through services offered by the medical, dental, pharmaceutical, clinical laboratory sciences (in vitro diagnostics), nursing, and allied health professions. Health care embraces all the goods and services designed to promote health, including “preventive, curative and palliative interventions, whether directed to individuals or to populations”.

Before the term health care became popular, English-speakers referred to medicine or to the health sector and spoke of the treatment and prevention of illness and disease.
