The global prevalence of allergic diseases is skyrocketing, affecting 30% to 40% of the world’s population. Allergic conditions include food allergies, anaphylaxis, asthma, eczema, allergic rhinitis, allergic conjunctivitis and reactions to drugs and insects. Often, these burdensome conditions start young, are overlapping and have the potential to be severe or fatal. A study of children with peanut allergy, for example, found that the median age of onset was 12 months; 40% to 60% of peanut-allergic children had concurrent asthma, atopic dermatitis, and/or other food allergies; and over a third (35%) had experienced anaphylaxis upon initial peanut exposure. Anaphylactic outcomes are worse when multiple allergic conditions are present.
