  1. aOxygen therapy includes nasal catheter oxygen inhalation and nasal continuous positive airway pressure (NCPAP);
  2. bCRP (C-Reactive Protein): Only when the value of CRP was greater than/ equal to 8, the specific value would be displayed;
  3. cIn s-RSV group, CRP values were collected from 195 patients, and there were 31 patients with CRP greater than 8; all the 47 cases in s-HRV group were tested for CRP, and 5 cases with CRP greater than 8; in co-infection group, CRP values were collected from 71 patients, and only 4 patients with CRP greater than 8;
  4. dGames-Howell test; e The clinical score system was showed in supplement 1
  5. *P value of < 0.05 was considered statistically significant
