Allergies in Children – Tracing the itch

Most of us are familiar with the term ‘allergy’, and use it quite frequently. By definition, an allergy is an abnormal response of the immune system if the human body to an allergen (an agent that can trigger allergy). Allergies in children are quite common in today’s context. Many children attending pediatric clinics today do so for allergy-related complaints.

An allergy can crop up at any age and can continue for months or years until the child outgrows it, or till the allergen is discovered and eliminated from the child’s environment. Allergies are usually a result of both genetic susceptibility and environmental stimulation.

For decades, medical science has taken advantage of this ability by using vaccination to create immunity, the immunologic memory of a disease. Allergic reactions happen when immune system incorrectly recognizes harmless foreign particles as potentially harmful.
