National Asthma and Allergy Awareness Month

Since 1984, the Asthma and Allergy Foundation of America (AAFA) has declared May to be “National Asthma and Allergy Awareness Month.” It is a peak season for people with asthma and allergies and a perfect time to educate patients, family, friends, co-workers, and other people about allergic diseases.

Quick Facts (Download Fact Sheet)

More than 100 million people in the United States have asthma and/or allergies. Some people may have more than one of these conditions.

  • Nearly 26 million people in the U.S. have asthma (20.7 million adults and 4.8 million children).1,2
  • About 20 million people in the U.S. have food allergies (16.0 million adults and 4.3 million children).3,4
  • About 80 million people in the U.S. have rhinitis due to nasal allergies, also called “hay fever” (66.4 million adults and 13.9 million children).3,4
  • There is no cure for asthma or allergies.
