All subjects were subjected to a complete history and clinical examination.

Chest X-ray was done to all subjects.

Nasopharyngeal and oropharyngeal swabs were obtained from all subjects and the presence of HRV was determined by PCR examination.

Results: By PCR method, 163 patients (81.5%) were positive for viral infection.
