An allergy is a response produced by the body’s immune system to any foreign substance which is not usually harmful. These foreign substances can be anything ranging from food products such as peanuts, egg, lactose, or pollen grains, dust particles, or pet dander.
There are several forms of allergies such as drug allergy, food allergy, insect allergy, latex allergy and others.
The prevalence of sensitivity to at least one allergen in school-aged children continues to rise and is approaching 50%.
The past years have observed an increase in the prevalence of allergic diseases since the advent of industrialization. The hike in Allergic disease prevalence can be attributed to hygiene standards, increasing pollution, and other reduced exposure to microbial substances during childhood. Moreover, more urbanized livelihood, the tendency of people to opt for tobacco products, reduced biodiversity, and (CO2 emissions) burning of solid fuel are also contributing to surge in allergic disease prevalence.
Allergy is a broader term, on the other hand, allergic diseases which are lined up due to the susceptibility to genetic factors are referred to as Atopic diseases. Atopic disease again refers to a spectrum of disorders characterized by abnormal sensitivity mediated by IgE such as eczema, asthma, and rhino conjunctivitis. Approximately 20% of Americans suffer from some form of allergic disease. However, Asthma is the most serious cause of allergic disease. Worldwide, around 300 million people suffer from Asthma. And around 250 million people suffer from food allergies. The allergic rhinitis prevalence estimated was even more shocking accounting for 400 million people worldwide.
The worst part of developing allergic reactions is that these diseases co-occur i.e., the same individual oftentimes develops more than on allergic disease. This calls for a more standard and integrated approach for the treatment of allergic diseases.
Due to the increasing allergic disease prevalence, and per-capita income of an individual there is an intense competition among pharma companies to dominate and occupy the major share of allergic disease market. However, lack of awareness and advanced medical technologies can be taken as allergic disease market barriers which are slowing the growth of the market.
