Introduction
Asthma is a serious global health problem affecting all age groups, with global prevalence ranging from 1% to 21% in adults , and with up to 20% of children aged 6–7 years experiencing severe wheezing episodes within a year. Although some countries have seen a decline in asthma-related hospitalisations and deaths [3], the global burden for patients from exacerbations and day-to-day symptoms has increased by almost 30% in the past 20 years . The impact of asthma is felt not only by patients, but also by families, healthcare systems and society. Asthma is one of the most common chronic diseases affecting children and young adults, and there is increasing recognition of its impact upon working-age adults, the importance of adult-onset asthma, and the contribution of undiagnosed asthma to respiratory symptoms and activity limitation in the elderly.
