      EPIDEMIOLOGY OF ASTHMA: Asthma is one of the most common chronic diseases in the world. It is estimated that about 300 million people in the world currently have asthma. Considerably higher estimates can be obtained with less conservative criteria for the diagnosis of clinical asthma.
      The rate of asthma increases as communities adopt western lifestyles and become urbanized. With the projected increase in the proportion of the world's population that is urban from 45% to 59% in 2025, there is likely to be a marked increase in the number of asthmatics worldwide over the next two decades. It is estimated that there may be an additional 100 million persons with asthma by 2025. In many areas of the world persons with asthma do not have access to basic asthma medications or medical care.
      The number of disability-adjusted life years (DALYs) lost due to asthma worldwide has been estimated to be currently about 15 million per year. Worldwide, asthma accounts for around 1% of all DALYs lost, which reflects the high prevalence and severity of asthma.
      It is estimated that asthma counts for about 1 in every 250 deaths worldwide. Many of the deaths are preventable, being due to suboptimal long-term medical care and delay in obtaining help during the final attack.
      INTERNATIONAL PREVALENCE: The prevalence of clinical asthma for selected countries was reported as follows: England, 15.3%; Brazil, 11.4%; U.S., 10.9%; Germany, 6.9%; France, 6.8%; Japan, 6.7%; Hong Kong, 6.2%; Singapore, 4.9%; Portugal, 4.8%; Italy, 4.5%; India, 3.0%; Russia, 2.2%; China, 2.1%; Greece, 1.9%.
      The true prevalence of asthma is difficult to determine due to the lack of a single objective diagnostic test, different methods of classification of the condition, differing interpretation of symptoms in different countries, as well as the uncertain influence of increasing public and professional awareness of asthma. In this report an arbitrary figure of 50% of the prevalence of "current wheezing" in children (self-reported wheezing in the previous 12-month period in 13- to 14-year-old children) has been used as the prevalence of "clinical asthma."
