Which aspect of health concern focuses on preventing illness before it occurs?

Primary prevention is the strategy aimed at preventing illness or injury before it occurs, which is essential in promoting overall health and wellness. This includes measures such as vaccinations, health education, lifestyle modifications, and screening programs that target risk factors to prevent the onset of diseases. By addressing potential health issues before they develop, primary prevention not only helps individuals maintain better health but also reduces the burden on healthcare systems.

In contrast, secondary prevention aims to detect diseases early and intervene to stop their progression, which occurs after the initial onset of a disease but before symptoms develop. Tertiary prevention focuses on managing and improving the quality of life for individuals already experiencing chronic illnesses, helping them to manage symptoms and prevent further complications. Health assessment involves evaluating health status and risks, which is more of a diagnostic tool rather than a proactive health strategy.
