OBJECTIVE. To describe the frequency of respiratory viruses and clinical characteristics in children with respiratory signs and symptoms in a tertiary care center in Mexico. MATERIAL AND METHODS. Patients with a clinical diagnosis of respiratory infection and a positive immunofluorescence result (Light Diagnostics) from January 2004 to October 2006 were included. RESULTS. From the 986 nashopharyngeal samples, 138 (14%) were positive by immunofluorescence. The frequency was: 80% RSV, 8% parainfluenza 1, 5% parainfluenza 3, 2% adenovirus, 2% influenza A, 1% parainfluenza 2 and 1% influenza B. CONCLUSIONS. Respiratory viruses were detected in 14% of samples tested. RSV was the most frequently identified virus and was associated with pneumonia and bronchiolitis in children younger than 3 years old.
