About incidence:

The medical term 'incidence' of Flu usually refers to the annual diagnosis rate of new cases of Flu. Prevalence is a different medical disease measure that refers to the estimated population of people who are managing Flu at any given time (e.g. prevalence includes people who have had a medical condition for a long time). For more information on prevalence and incidence statistics, see about prevalence and incidence statistics.
