Jun 13, 2022 · In statistics, prevalence is the proportion of individuals in a population who have a specific characteristic at a certain time period. Researchers typically measure prevalence by taking a random sample of individuals from the population and simply counting how many of the individuals in the sample have the specific characteristic.
Nov 6, 2020 · Higher prevalence could mean a prolonged survival without cure or an increase of new cases, or both. A lower prevalence could mean that more people are dying rather than being cured, a rapid recovery, and/or a low number of new cases.
Prevalence may be reported as a percentage (5%, or 5 people out of 100), or as the number of cases per 10,000 or 100,000 people. The way prevalence is reported depends on how common the characteristic is in the population.
