Anaphylaxis is a severe allergic reaction triggered by a variety of things, from getting stung by a bee to eating just one nut. It comes on quickly and can kill a person in a few minutes.
Kids are at special risk, as many have unrecognized allergies. The Centers for Disease Control and Prevention estimates that as many as 6% of all children have a food allergy. Thanks to technology, however, we have medicines and medicine-delivery systems, such as epinephrine auto-injectors, that can counter anaphylaxis in just as immediate a fashion.
State law allows children with diagnosed allergies to keep their prescribed epinephrine auto-injectors, commonly known under the brand name EpiPen, at school in case of a reaction. It's a good law but leaves out all the children who have no idea whether they have severe allergies.
