Estimates from a skin test survey suggest that allergies affect as many as 40 to 50 million people in the United States.1
Allergic diseases affect more than 20% of the U.S. population. 2
Allergic diseases are the sixth leading cause of chronic disease in the United States. 2
Over eight million visits to office-based physicians each year are attributed to allergic rhinitis.4
In 1993, it was estimated that total cost associated with allergic rhinitis in the United States was $3.4 billion, of which $2.3 billion represents medications and $1.1 billion represents physician billing.
It is estimated that in 1998, increased absenteeism and reduced productivity due to allergies cost U.S. companies more than $250 million.7
Sinusitis develops in approximately 31 million Americans each year.8
People suffering from sinusitis miss an average of four days of work each year.8
There are more than 18 million office visits to primary care physicians resulting in a diagnosis of sinusitis annually.8
In 1996, overall health care expenditures attributable to sinusitis in the United States were estimated to be over $5.8 billion.9
Between 2 and 3% of hospitalized patients have allergic drug reactions.10
Allergic dermatitis (itchy rash) is the most common skin condition in children younger than 11 years of age. The percentage of children diagnosed with it has increased from 3% in the 1960’s to 10% in the 1990’s.11
Contact dermatitis and other eczema was diagnosed at over 7.1 million office visits to physicians and 430,000 hospital outpatient visits.12
Urticaria (hives) and angioedema (swelling of the deeper layers of the skin) together affect approximately 15% of the U.S. population every year.11
Approximately 100 people in the United States die each year from food-related anaphylaxis.13
Eight percent of children younger than six years experience food intolerances. Of this group, 2 to 4% appear to have allergic reactions to food.
In adults, an estimated 1 to 2% are sensitive to food or food additives.14
Peanut and/or tree nut (e.g. walnut, almond and cashew) allergy affects about three million Americans, or 1.1% of the population.15
At least 40 deaths occur annually in the United States from reactions to insect stings. 16
A severe allergic reaction known as anaphylaxis occurs in 0.5 to 5% of the U.S. population as a result of insect stings.17
Venom immunotherapy prevents systemic reactions in stinging insect-sensitive patients 97% of the time.16
Between 1988 and 1992, latex allergy was estimated to affect 1,000 people.18
