Which set names the components of the epidemiologic triangle in occupational health?

• A. Agent, host, environment
• B. Pathogen, victim, exposure
• C. Dose, duration, route
• D. Hazard, exposure, receptor

Answer: (A)

The epidemiologic triangle in occupational health revolves around three interacting components: the agent (the factor that can cause harm), the host (the worker who may be affected), and the environment (the workplace conditions that influence exposure and disease development). This trio explains why a disease or injury occurs and how preventive measures work—altering the agent, strengthening or reducing host susceptibility, or changing environmental factors to lower exposure. For example, solvent exposure in a poorly ventilated area involves the agent (solvent), the host (the worker), and the environment (ventilation, work practices, controls). The other options don’t fit this classic three-part framework: they either refer to details about exposure (dose, duration, route) or use nonstandard terms (pathogen, victim, exposure; hazard, exposure, receptor) that don’t name the three components of the triangle.
