A Comprehensive Review on Allergic Disorders, Their Epidemiological Trend and Barriers in Management

Allergy is an important public health disorder. Common allergic disorders include asthma, rhinitis, conjunctivitis, atopic eczema, contact dermatitis, and food and drug allergies. In this article, allergic disorders are discussed comprehensively, along with their epidemiological trends, quality of care, and barriers in management. Allergic disorders have increased in prevalence throughout the world, except for a few foci (e.g., Spain) where asthma is decreasing. Prevention of allergen exposure, pharmacotherapy, and immunotherapy are different modes of controlling allergy. Extensive training, research, and awareness can improve the quality of allergy care.
