Statistics

Statistics related to asthma and allergies:
According to the latest available from the National Institute of Allergy and Infectious Diseases (NIAID), consider the following statistics:

Asthma:

·        More than 17 million people in the US have been diagnosed with asthma.

·        Asthma is the sixth most common chronic condition in the US.

·        Asthma affects more than 4.8 million US children, making it the most common serious and chronic disease among children.

·        Asthma accounts for 10 million absences from school each year.

·        Asthma is 26 percent more prevalent in African-American children than in Caucasian children.

·        African-American children with asthma, most often from inner city populations, generally experience more severe disability from asthma and have more frequent hospitalizations than do Caucasian children.

·        Asthma is the third most common cause of childhood hospitalizations under the age of 15.

·        More than 200,000 children with asthma experience more severe symptoms due to exposure to secondhand smoke.   

·        About 10 million visits annually to office-based physicians result in a diagnosis of asthma.

·        Asthma cases and asthma deaths have been on the rise. From 1979 to 1996, asthma deaths have risen 120 percent from 2,598 to 5,667.

·        Hospitalizations for asthma have increased 256 percent from 1979 to 1996, to 474,100 people annually.

·        Asthma treatment costs an estimated $11.3 billion, including direct and indirect expenditures each year.

·        Asthma causes nearly 3 million lost workdays each year for people over age 18. 

Allergy:

·        Previous surveys estimate that allergies affect as many as 40 to 50 million people in the US.

·        Pollen allergy (hay fever or allergic rhinitis) affects nearly 10 percent of the people in the US (26 million people), not including those with asthma.

·        Allergic dermatitis (itchy rash) is the most common skin condition in children younger than 11 years of age.

·        Urticaria (hives; raised areas of reddened skin that become itchy) and angioedema (swelling of throat tissues) together affect approximately 15 percent of the US population every year.

·        Chronic sinusitis, most often caused by allergies, affects nearly 35 million people in the US.

·        Allergic drug reactions, commonly caused by antibiotics such as penicillin and cephalosporins, occur in 2 to 3 percent of hospitalized patients.

·        Eight percent of children younger than 6 years old experience food intolerances. Of this group, 2 to 4 percent appear to have reproducible allergic reactions to food. In adults, an estimated 1 to 2 percent are sensitive to foods or food additives.

·        A severe allergic reaction known as anaphylaxis occurs in 3.3 percent of the US population as a result of insect stings. At least 40 deaths each year result from insect sting anaphylaxis.
