Prevalence of asthma is 8%, prevalence of AR is 3 times higher (24%). 40% of patients with AR have asthma, 80% of patients with asthma have AR.

How the allergens change during the season: mnemonic TGR MI DC/DC ("a Tiger with an MI went to DC")

"There's spring time, where you have the tree pollen. Summer time, where you have the grass pollens. And then there's the fall time when you have the weed pollen.”

This sequence is remembered by the mnemonic TGR MI DC/DC ("a Tiger with an MI went to DC").

Allergic Rhinitis and its Impact on Asthma (ARIA): Achievements in 10 years and future needs. ARIA has reclassified AR as mild/moderate-severe and intermittent/persistent. This classification closely reflects patients' needs and underlines the close relationship between rhinitis and asthma.
