Detailed explanation-1: -Type I hypersensitivities include atopic diseases, which are an exaggerated IgE mediated immune responses (i.e., allergic: asthma, rhinitis, conjunctivitis, and dermatitis), and allergic diseases, which are immune responses to foreign allergens (i.e., anaphylaxis, urticaria, angioedema, food, and drug allergies).
Detailed explanation-2: -Hay fever is the common name for allergic rhinitis . Hay fever is caused by the nose and/or eyes coming into contact with environmental allergens, such as pollens (grasses, weeds or trees), dust mite, moulds and animal dander. Most people associate hay fever with spring, when airborne grass pollens are at their peak.
Detailed explanation-3: -Type I reactions (i.e., immediate hypersensitivity reactions) involve immunoglobulin E (IgE)–mediated release of histamine and other mediators from mast cells and basophils. Examples include anaphylaxis and allergic rhinoconjunctivitis.
