Which of the following is an example of primary prevention?

Primary prevention aims to prevent disease and promote health before any signs or symptoms occur. Providing health education about proper hygiene exemplifies primary prevention because it empowers individuals with knowledge and strategies to prevent illnesses by fostering good health practices. This includes teaching the importance of regular hand washing, safe food handling, and other hygiene practices that reduce the risk of infections and promote overall health.

While conducting blood pressure screenings and administering vaccines are important health strategies, they fall under secondary and tertiary prevention, respectively. Blood pressure screenings aim to detect existing health issues early, thus allowing for timely intervention. Administering vaccines also works to prevent disease, but in a more targeted way, and can be considered part of a broader immunization strategy. Developing rehabilitation programs focuses on helping individuals recover from illness or injury, placing it in the realm of tertiary prevention. In contrast, the focus of health education about proper hygiene is purely on preventing health issues before they arise, aligning with the principles of primary prevention.
