PCR‐based virus detection in 359 upper airway samples and in 92 sets of paired upper airway and sputum samples
| Virus detections in upper airway samples (n = 359) | Virus detections in paired upper airway and sputum samples (n = 92) | ||
|---|---|---|---|
| Number* (%) | Upper Airway Number (%) | Sputum Number (%) | |
| Rhinovirus | 83 (23·1) | 20 (21·7) | 20 (21·7) |
| Adenovirus | 6 (1·7) | 4 (4·4) | 3 (3·3) |
| Influenza A | 1 (0·3) | 1 (1·1) | 3 (3·3) |
| Influenza B | 3 (0·8) | 0 (0) | 0 (0) |
| Parainfluenza 1 | 3 (0·8) | 1 (1·1) | 0 (0) |
| Parainfluenza 2 | 0 (0·0) | 0 (0) | 0 (0%) |
| Parainfluenza 3 | 7 (1·9) | 2 (2·2) | 1 (1·1) |
| Parainfluenza 4 | 1 (0·3) | 0 (0) | 0 (0) |
| Respiratory syncytial virus | 2 (0·6) | 0 (0) | 0 (0) |
| Coronavirus | 3 (0·8) | 2 (2·2) | 3 (3·3) |
| Human metapneumovirus | 6 (1·7) | 1 (1·1) | 0 (0) |
*108 positive samples accounted for 115 positive results: 102 samples with one virus detected, five samples with two viruses detected, and one sample with three viruses detected. The five samples with two viruses detected all had rhinovirus with another virus, including adenovirus (n = 2), human metapneumovirus (n = 1), parainfluenza 1 (n = 1), and parainfluenza 3 (n = 1). The one sample with three viruses detected had adenovirus, human metapneumovirus, and parainfluenza 3.
