Background: Wheezing is the most common symptom of childhood respiratory tract illnesses. It is important not only for its associated acute morbidity, but also for the fact that early childhood Wheezing confers a high risk for asthma. Epidemiological studies front various countries show that 10-15% of children < 1 year of age and 25% of children < 5 years of age have wheezing-associated respiratory tract illness, and one-third of these children develop asthma later in life.
