{{Main article|Health policy|Public health|Health administration|Disease management (health)}}
The management of any health system is typically directed through a set of [[health policy|policies and plans]] adopted by government, private sector business and other groups in areas such as personal healthcare delivery and financing, [[pharmaceutical policy|pharmaceuticals]], [[health human resources]], and [[public health]].{{citation needed|date=June 2023}}

Public health is concerned with threats to the overall health of a community based on [[population health]] analysis. The population in question can be as small as a handful of people, or as large as all the inhabitants of several continents (for instance, in the case of a [[pandemic]]). Public health is typically divided into [[epidemiology]], [[biostatistics]] and [[Health care|health services]]. [[Environmental health|Environmental]], social, [[Mental health|behavioral]], and [[Occupational safety and health|occupational health]] are also important subfields.{{citation needed|date=June 2023}}

Today, most governments recognize the importance of public health programs in reducing the incidence of disease, disability, the effects of ageing and [[health equity|health inequities]], although public health generally receives significantly less government funding compared with medicine. For example, most countries have a [[vaccination policy]], supporting public health programs in providing [[vaccination]]s to promote health. Vaccinations are voluntary in some countries and mandatory in some countries. Some governments pay all or part of the costs for vaccines in a national vaccination schedule.{{citation needed|date=March 2024}}

The rapid emergence of many [[Chronic condition|chronic diseases]], which require costly [[chronic care management|long-term care and treatment]], is making many health managers and policy makers re-examine their healthcare delivery practices. An important health issue facing the world currently is [[HIV/AIDS]].<ref>{{cite web |url=http://www.euphix.org/object_class/euph_hiv_aids.html |title=European Union Public Health Information System – HIV/Aides page |publisher=[[EUPHIX|Euphix]].org |access-date=6 August 2011 |archive-url=https://web.archive.org/web/20110726043233/http://www.euphix.org/object_class/euph_hiv_aids.html |archive-date=26 July 2011 |url-status=dead }}</ref> Another major public health concern is [[diabetes]].<ref>{{cite web |url=http://www.euphix.org/object_class/euph_diabetes.html |title=European Union Public Health Information System – Diabetes page |publisher=Euphix.org |access-date=6 August 2011 |archive-url=https://web.archive.org/web/20110726043253/http://www.euphix.org/object_class/euph_diabetes.html |archive-date=26 July 2011 |url-status=dead }}</ref> In 2006, according to the World Health Organization, at least 171 million people worldwide had diabetes. Its incidence is increasing rapidly, and it is estimated that by 2030, this number will double. A controversial aspect of public health is the control of [[tobacco smoking]], linked to cancer and other chronic illnesses.<ref>{{cite web |url=http://www.euphix.org/object_class/euph_health_behaviours_smoking.html |title=European Union Public Health Information System – Smoking Behaviors page |publisher=Euphix.org |access-date=6 August 2011 |archive-url=https://web.archive.org/web/20110801225934/http://www.euphix.org/object_class/euph_health_behaviours_smoking.html |archive-date=1 August 2011 |url-status=dead }}</ref>

[[Antimicrobial resistance|Antibiotic resistance]] is another major concern, leading to the reemergence of diseases such as [[tuberculosis]]. The [[World Health Organization]], for its [[World Health Day|World Health Day 2011]] campaign, called for intensified global commitment to safeguard antibiotics and other [[antimicrobial]] medicines for future generations.{{citation needed|date=March 2024}}
