Allergic asthma is one of the most severe forms of childhood allergic diseases, and treatment can include immunotherapy, also known as desensitization therapy. Most children’s conditions can be controlled, and even cured, with proper treatment. Dust mites are the leading allergen causing asthma. In addition to inhaled allergens triggering asthma, other factors such as infections and environmental factors can exacerbate asthma attacks. Observing allergens daily can help prevent asthma.
