Preparing for anaphylactic reactions in severely allergic children.

The incidence of severe allergies, especially to food, has increased dramatically in the United States. The number of children who are allergic to peanuts has more than doubled in the past five years. Severe allergies often cause anaphylaxis, which has a wide range of symptoms, including tightness in the chest, difficulty breathing and swallowing, itchy mouth and skin, nausea, hives, and fainting, and can cause death. Preparation and acting quickly in an emergency situation is key for affected children.
