ISLAMABAD - The World Allergy Day would be observed throughout the Globe including Pakistan tomorrow (Tuesday). The theme of this year's event is "You can control your asthma". Latest research on Asthma reveals that more than 300 million people around the world are suffering from Asthma. Toward this end, in 2005, July 8 was declared World Allergy Day. This event is an outgrowth of a project known as Prevention of allergies and allergic asthma, which was initiated jointly by WHO and WAO. The observance of the World Allergy Day aims to increase awareness of allergies among the physicians and patients. The World Allergy Day is intended to help increase worldwide awareness of allergy related problems and to disseminate well founded information about how allergies can be prevented and how their symptoms and effects can be mitigated. The WAO survey of 30 countries revealed that of the 1.2 billion people, 22 percent or some 250 million of them suffer from an allergic disease. "Allergies are the epidemic of the 21st century, and we need to heighten worldwide awareness of these disorders," stated WAO president Prof. Carlos E. Baena-Cagnani. Chronic Allergic Respiratory diseases include allergic rhinitis, allergic rhinosinusitis, allergic asthma, allergic occupational asthma, allergic bronchopulmonary aspergillosis and other airway disorders caused by exposure to allergens. Allergies also have a strong impact on patients' quality of life in that social life suffers, children's learning abilities are often impaired, and adults' work productivity can decline to the point of complete job disability. In addition to the significant changes wrought by allergies in patients' lives, allergic disorders are also extremely costly from an economic standpoint. According to State of World Allergy Report 2008, as allergic diseases continue to increase in prevalence and complexity worldwide, there is an urgent need to create awareness of the global burden of allergies and the need to train more physicians to care for allergy sufferers. The prevalence of allergic disorders such as hay fever, asthma and neurodermitis has increased so drastically over the past decade that experts speak in terms of an epidemic-like situation.   According to World Allergy Organisation (WAO) president Prof. Carlos E. Baena-Cagnani from Argentina, there are now 300 million asthma patients worldwide. In Germany, up to 4.4 per cent of all adults and approximately three to seven per cent of all children and teenagers suffer from asthma, which is triggered by allergies in 85 per cent of all cases.  Allergies are not a trivial disorder. Each year, 2,700 Germans and over 180,000 people worldwide die from asthma.  Hay fever gives rise to annual costs of approximately EUR16.5 billion worldwide, and in the US alone, the annual asthma bill runs to approximately EUR10.5 billion. Thus, therapies are urgently needed, although the scope and impact of allergic disorders are still underestimated.
