Question: 1 / 400

What is secondary prevention in public health?

Initiatives aimed at reducing risk factors in healthy people

Interventions aimed at early disease detection and prompt treatment to prevent progression

Secondary prevention in public health refers to interventions that are designed to identify diseases at an early stage when treatment can be more effective, thereby preventing the progression of diseases. These initiatives can include screening programs, regular health check-ups, and diagnostic tests aimed at catching health issues before they develop into more serious conditions. For example, mammograms for early detection of breast cancer or blood tests for early detection of diabetes illustrate secondary prevention techniques.

This approach is distinct because it targets those who may already have a disease but are asymptomatic, making it possible to intervene before any symptoms worsen or complications arise. Effective secondary prevention not only improves individual health outcomes but can also reduce healthcare costs and improve overall public health by decreasing the prevalence of advanced diseases.
