Enter how many days a week you have symptoms, how many consecutive weeks they have run, and which of four items apply. The page looks up the ARIA duration class and severity class and shows both axes together. The four items are disturbed sleep, impaired daily activities, leisure or sport, impaired school or work, and troublesome symptoms.
ARIA calls symptoms intermittent when they occur on fewer than four days a week or run for fewer than four consecutive weeks, and persistent when they occur on more than four days a week and run for four weeks or more. Severity is mild when none of the four items is present and moderate-severe when at least one is. Nothing is weighted, so there is no score. In a French primary care survey of 3,052 people, 80% of the moderate-severe group reported activity impairment against 40% of the mild group, and impairment correlated more strongly with severity than with duration (as of October 2026).
Exactly four days a week together with four weeks or more falls into neither class as the source words it, so the page reports that gap instead of forcing a class. Some sources also express the duration criterion as four weeks in a year rather than four consecutive weeks. This system classifies symptoms you already know you have; it is not an allergy diagnosis, and the trigger allergen can only be identified by skin or blood testing. Having none of the four items does not mean you do not have allergic rhinitis. Treatment is decided in consultation.
Frequently asked questions
The source defines intermittent as fewer than four days a week and persistent as more than four, so exactly four is named in neither class. The page reports that rather than guessing.
Because the published ARIA rule is simply that any one of the four items puts the case in the moderate-severe class. No published weighting exists for the individual items, so no score was invented.
No. It is a classification applied to symptoms you already know about, not a diagnosis. The trigger allergen can only be confirmed with skin prick or blood testing.
