Atopy is the inheritance tendency to develop allergies.
Atopy increases your risk of developing allergic diseases, especially after allergen exposure.
The prevalence of asthma and rhinitis – two major forms of allergies – was one and 10 percent respectively in 1964 in the country. But, new data as per WAO (World Allergy Organization) shows that about 14 per cent people now have asthma, while over 20 per cent are suffering from allergic rhinitis (AR) which results from an IgE-mediated inflammation of the nasal mucosa. Currently, about 20 to 30 per cent of people in India are having one or more allergic diseases and their prevalence is rising dramatically, the WAO said.
