Ehrlichiosis: Rare Disease Status
Ehrlichiosis is listed as a "rare disease"

This page presents a variety of statistics about Ehrlichiosis.
The term 'prevalence' of Ehrlichiosis usually refers to the estimated population
of people who are managing Ehrlichiosis at any given time.
The term 'incidence' of Ehrlichiosis refers to the annual diagnosis rate,
or the number of new cases of Ehrlichiosis diagnosed each year.
Hence, these two statistics types can differ:
a short-lived disease like flu can have high annual incidence but low prevalence,
but a life-long disease like diabetes has a low annual incidence but high prevalence.
