Strategies Used in Primary Prevention

Primary prevention involves two complementary strategies: population strategy and high-risk individual strategy.
Population strategy focuses on the whole population, aiming to reduce average risk, and is directed towards socioeconomic, behavioral, and lifestyle changes.
High-risk individual strategy focuses on individuals at high risk due to particular exposure, requiring detection of individuals at risk, but is of limited effect.

Examples of Primary Prevention

Immunization is a primary prevention tool, which has reduced the incidence of immunizable diseases and led to the eradication of smallpox and the elimination of polio and tetanus.
Use of disposable syringes has prevented the spread of hepatitis B and HIV infection.
Condoms have been used to prevent HIV infection.
Washing hands and wearing protective masks are universally used to prevent Covid-19.
Sanitation programs, such as safe water supply, sewage disposal, and protection of food and milk, can prevent diseases transmitted by common vehicles.
Vector control measures can prevent diseases transmitted by vectors mechanically (e.g., typhoid and hepatitis A) or biologically (e.g., yellow fever and malaria).

This quiz covers the two main strategies used in primary prevention, focusing on the whole population and high-risk individuals. It explores approaches to reducing average risk and dealing with socioeconomic, behavioral, and lifestyle changes.
