Cough is a frequent symptom of infection in childhood, but if it persists for weeks or months, it has to be thoroughly examined.

Sometimes the cough is a clear result of a persisting infection in upper or lower respiratory tract, but also it can be caused by inadequate kind of food, reflux disease, inflammation of an other etiology, foreign bodies, changes at the level of trachea or bronchias  or some processes that oppress the bronchi from the outside.

In any case it is important for the practitioner to have knowledge of all possible causes of cough, in order to perform all necessary diagnostic procedures and adequate treatment.
