About prevalence and incidence statistics:
The term 'prevalence' of Allergy-like conditions usually refers to the estimated population
of people who are managing Allergy-like conditions at any given time.
The term 'incidence' of Allergy-like conditions refers to the annual diagnosis rate,
or the number of new cases of Allergy-like conditions 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.
