Allergy occurs when a person’s immune system reacts to substances in the environment that are harmless for most people. Substances that can trigger an allergic reaction are called allergens.
People can be allergic to many things, such as pollen, mould, dust mites, animal dander or saliva, insect stings or bites, medication, food, and latex. Allergic disease also includes conditions such as eczema (atopic dermatitis), allergic rhinitis (hay fever), allergic conjunctivitis, and allergic asthma.
