Which term describes the probability and severity of adverse health outcomes following exposure to hazards?

• A. Hazard
• B. Risk
• C. Exposure
• D. Vulnerability

Answer: (B)

The main idea here is describing how likely harm is and how severe that harm could be after people come into contact with something hazardous. The term that captures both the chance of an adverse health outcome and how serious that outcome could be is risk. In health and humanitarian practice, risk combines the likelihood of an event occurring with the magnitude of its consequences, and it often reflects not just the hazard itself but also how people are exposed to it and how vulnerable they are. For example, contaminated floodwaters present a hazard, but the actual risk to a community depends on how many people are exposed to that water and how susceptible they are (age, nutrition, existing illnesses), which together determine the potential health impact. Hazard describes the potential source of harm, exposure is about contact with that hazard, and vulnerability is about the population’s susceptibility; none of these alone fully conveys both how likely harm is and how bad it could be.
