[The child and his allergenic environment].

The child and his allergenic environment. Environment's allergens may promote sensitization and after that generate symptoms (allergy). Allergic diseases are frequent in childhood and food allergy increase. Environmental factors may be aeroallergens but also food allergens. The first step of the therapeutic possibilities is to avoid the allergens, with lifestyle modifications. Emergency plan is necessary for school. A first prevention level is feasible and probably useful for food allergy, but not for respiratory allergy.
