Anaphylaxis (pronounced "an-a-fi-LAX-is") is an allergic reaction that is rapid in onset and is life-threatening. It occurs when someone comes into contact with food or other trigger to which they are allergic. Life-threatening allergic reactions are unpredictable. Anaphylaxis is a serious public health problem in the U.S, with up to 43 million people at risk.

While many already know about their allergic triggers, there may be others who are not aware and could also be at risk for anaphylaxis. Avoidance of allergic triggers is the crucial first step in managing potentially life-threatening (severe) allergies, but allergic triggers are not always obvious. Accidental exposure resulting in anaphylaxis can happen anywhere, in or outside school, and it's important to be ready in case anaphylaxis occurs.
