When will incidence comeclosest to being equivalent toprevalence? (Epidemiologyquestion)?
Prevalence is the rate of incidence-the prevalence rate. This would be usually stated relative to the affected population. An incidence rate, for example of 22 per 1000 people would have a prevalence in the population of 2.2%. The prevalence versus the incidence of new cases.
