Prevalence and Incidence of Peanut Allergy

Prevalance of Peanut Allergy:

Peanut or tree nut allergies affect approximately 3 million Americans and cause the most severe food-induced allergic reactions. (Source: excerpt from Allergy Statistics: NIAID)

About prevalence and incidence statistics:

The term 'prevalence' of Peanut Allergy usually refers to the estimated population of people who are managing Peanut Allergy at any given time. The term 'incidence' of Peanut Allergy refers to the annual diagnosis rate, or the number of new cases of Peanut Allergy 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. For more information see about prevalence and incidence statistics.
