Morphology
prevalence = prevalent (semi-transparent) = preval + ence
Morphologically derived from 'prevalent', but the epidemiological sense 'proportion of a population with a condition at a specific time' is a specialized technical extension of the general idea of being widespread.
Etymology
The word prevalence keeps the Latin root praevalere ('to be stronger' or 'to prevail'), which gives the image of something that 'wins out' or is common in a place. So in health studies prevalence means how many people in a population have a disease at one time.
