| ≥1 virus | 177 (27.2%) | 209 (32.2%) |
| Influenza A or B | 50 (7.7%) | 43 (6.6%) |
| Influenza A | 40 (6.2%) | 29 (4.5%) |

| Entero‐rhino | 130 (20.0%) | 159 (24.5%) |
| MPV | 12 (1.8%) | 25 (3.8%) |
| Parainfluenza 1 | 1 (0.2%) | 0 (0.0%) |

| Parainfluenza 3 | 12 (1.8%) | 9 (1.4%) |
| RSV | 7 (1.1%) | 10 (1.5%) |

The sum of participants with confirmed infection with the different types of viruses is greater than the number for ≥1 virus because of those participants infected with more than one type of virus.
