Which of the following is primarily concerned with the prevention of diseases and promoting overall health?

The focus of public health is on the prevention of diseases and the promotion of overall health within populations. It encompasses a wide range of activities aimed at protecting and improving the health of communities through education, policy-making, and research. Public health initiatives often include vaccination programs, health education campaigns, disease surveillance, and efforts to address social determinants of health, all of which work together to prevent illness and enhance well-being on a large scale.

In contrast, clinical health is more centered on the treatment and management of individual patients’ diseases and conditions in healthcare settings. Environmental health, while it plays an essential role in public health, specifically looks at how environmental factors impact human health, such as air and water quality. Behavioral health focuses on how individual behaviors influence health outcomes, addressing issues such as mental health and substance use. Although these other domains contribute to health in various ways, none have the same broad preventative mandate as public health. Therefore, public health is the most accurate answer for initiatives aimed at disease prevention and overall health promotion.
