Tertiary prevention focuses on what?

• A. Elimination of hazards at source
• B. Diagnosis of occupational illness and alteration
• C. Early detection and screening
• D. Primary workplace safety training

Answer: (B)

Tertiary prevention focuses on workers who already have an illness or injury. The goal is to minimize disability and prevent further complications by diagnosing the condition accurately and then guiding treatment and work modification to maximize function. This often involves rehabilitation, adjustments to job tasks or the work environment, and return-to-work strategies that help prevent deterioration. By contrast, eliminating hazards at the source is primary prevention, early detection and screening is secondary prevention, and basic workplace safety training likewise aims to prevent disease or injury before it occurs.
