Asthma is widely and differently distributed around the world.It is common mostly in children ( 35 % ) and less common in adults ( 10 % ).This shows children are at greater risk of asthma than adults Asthma incidence is 1%/y in average. Severe asthma is reported by 1-3% of the general population (children and adults respectively).
Recent population show that the asthma prevalence increase observed worldwide in the past 30 years has now stopped in industrialised countries. Such phenomenon has been paralleled by an increase in the use of asthma medications.
However,there has been a significant increase of asthma in the Western world in the past three decades.
