A hypothetical example of the incidence and prevalence rates for influenza in Valparaiso, Indiana. There are 200 new cases of influenza this month in Valparaiso, Indiana, and the total population is 100,000, the incident rate is 200/100,000= 0.002 or 0.2%. During the flu season, there are 2,000 total cases of influenza in Valparaiso, Indiana, and the population is 100,000. The prevalence is 2000/100,000= 0.02 or 2%. does this make sense
