Cough is one of the common symptoms, which is usually related to
respiratory infections for
children. This symptom is not considered crucial. Published data reported that the
community prevalence of
chronic cough in
primary school children is 5%-10%, while the
prevalence is likely to be higher in younger
children. The cause of
persistent cough should be investigated. There were significant differences in the causes and management for
cough according to age.
Chronic cough is defined as duration of 4 weeks or longer. Common culprits for
chronic cough in
children are different from those in
adults. The authors reviewed articles about
chronic cough of
children to help improve the
understanding and management for pediatric
chronic cough.
