An increase in incidence results from plant-to-plant (entity-to entity) disease spread and in part is related to the distance from the inoculum source. An increase in severity results from increased disease on or within a single plant (or entity) and is related to a very much more localized dispersal.

This measure is called point prevalencea because it refers to a single point in time. It is often referred to simply as prevalence.
