Cough
Though cough is common in all age groups, it is one of the most common symptoms of childhood illness. Coughing is the body's way of removing foreign material or mucus from the lungs and throat. The two general classifications of cough are productive cough (producing phlegm or mucus from the lungs) and nonproductive cough (dry and not producing any mucus or phlegm).
Acute cough is most often caused by the common viral upper respiratory tract infection. The cough is usually secondary to stimulation of nasal, pharyngeal, and laryngeal mucosa receptors. This results from the secretions of the nose and sinuses draining into the throat.
