Allergies affect as many as 60 million Americans, or one in every five people in the United States.

Allergens include dust, pollen, medicines, food, and many other ordinary substances. Allergic reactions range from mild symptoms, such as itching or respiratory congestion, to deadly responses, such as anaphylactic shock.Synopsis
