Measure of Incidence

Incidence is the number of new infections appearing in a population within a period of time.

This measure is very useful for assessing temporal dynamics. The same colonies must be repeatedly surveyed in order to track new infections within the population. This measure is different than prevalence because it tracks a rate of infection, not just the proportion of individuals affected. This value can be calculated by dividing the number of new infections by the time period of the study.
