What are the costs of Allergies?

• The cost of nasal allergies is between $3 billion and $4 billion each year.
• Food allergies cost about $25 billion each year.
What Are Indoor and Outdoor Allergies?
• Indoor and outdoor allergies can lead to sinus swelling/pain, itchy/watery eyes,
runny nose, nasal congestion, and sneezing. Airborne allergens can cause
seasonal (sometimes called “hay fever”) or perennial (called “constant”
“persistent”) allergies.
• Many people with allergies often have more than one type of allergy. The most
common indoor/outdoor allergy triggers are: tree pollen, grass pollen, weed
pollen, mold spores, dust mites, cockroaches, cat and dog dander, and rodent
dander.
How Common Are Seasonal Allergies?
• In 2021, approximately 81 million people in the U.S. were diagnosed with seasonal
allergic rhinitis (hay fever). This equals around 26% (67 million) of adults and 19%
(14 million) of children.1,2
• Seasonal allergic rhinitis is an allergic reaction to pollen from trees, grasses, and
weeds. This type of rhinitis occurs mainly when pollen from trees (spring), grasses
(summer), and weeds (fall) are in the air.
• In 2021, non-Hispanic Black children and non-Hispanic White children were more
likely to have a seasonal allergy than Hispanic and non-Hispanic Asian children.
• The same triggers for indoor/outdoor allergies can also cause eye allergies
(allergic conjunctivitis).
