thumb|upright=1.8|A depiction of prevalence In epidemiology, prevalence is the proportion of a particular population found to be affected by a medical condition (typically a disease or a risk factor such as smoking or seatbelt use) at a specific time. It is derived by comparing the number of people found to have the condition with the total number of people studied and is usually expressed as a fraction, a percentage, or the number of cases per 10,000 or 100,000 people. Prevalence is most often used in questionnaire studies.

variable or factor associated with an increased risk of disease or infection, with the association being frequently correlational and not necessarily causal

measure of the probability of occurrence of a given medical condition in a population within a specified period of time

experiment in which information about the test is masked to reduce bias
