What are the three levels of disease prevention?

The three levels of disease prevention are primary, secondary, and tertiary. This framework is essential in public health as it describes different strategies to prevent disease and promote health at various stages.

Primary prevention aims to prevent diseases before they occur, focusing on health promotion and risk reduction. This includes measures such as vaccination, health education, and lifestyle modifications that can prevent the onset of disease.

Secondary prevention targets the early detection and prompt intervention of disease to halt progression. This level often involves screening tests, regular check-ups, and early treatment to prevent more serious health issues from developing.

Tertiary prevention is about reducing the impact of an established disease by providing rehabilitation and support to help individuals lead a more productive life, thus minimizing complications and preventing further deterioration.

Combining these three levels allows for a comprehensive approach to health management, addressing not only the prevention of disease but also the treatment and management of existing conditions. Options that suggest a single aspect, like observation or diagnosis, do not encompass this broad strategy, which is why primary, secondary, and tertiary are recognized as the essential levels of disease prevention.
