Indoor Allergy in the Respiratory Tract Region

Abstract

In recent years allergic diseases have been increasing, especially allergic rhinitis and bronchial asthma, which are chronic inflammatory disorders of the airways. Risk factors for airway hyperresponsiveness can be classified into host factors and environmental factors. Exposure to allergens such as domestic mites, fungi, animal allergens, formalin and photochemical smog (nitrogen oxides, ozone) are recognized as major environmental factors. Both indoor and outdoor irritants which contribute to environmental change become injurious to humans, animals and plants paralleling our socioeconomic condition. In children who are exposed to maternal smoking, there is evidence that exposure to tobacco increases their risk of developing asthma and wheeze. Therefore initiation of appropriate solutions is important for successful management and prevention of allergic diseases.
