Figure 1. Pathogen detection and monthly distribution of single virus detected among hospitalized adults with viral pneumonia, 2017-2020. Patients’ numbers of a specific virus detected were showed. Numbers in the bars represented the percentages of bacterial/fungal co-infection. The proportions of influenza A (Flu A), influenza B (Flu B), severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), human rhinovirus (HRV), adenovirus (AdV), coronavirus (CoV), parainfluenza (PIV), respiratory syncytial virus (RSV), human metapneumovirus (HMPV) and mixed viral infection () were indicated in the pie chart.
Figure 2. Numbers of specific bacterial/fungal identified in patients hospitalized with viral pneumonia. *, other bacteria included 1Proteus mirabilis , 1 Chlamydophila pneumonia , and 1Cupriavidus paucula isolated from low respiratory specimens. 1Peptostreptococcus anaerobius and 1 S. gallolyticusisolated from blood. Numbers in the bar represented the percentage of antibiotic-resistance.
Figure 3. Survival of viral pneumonia patients between virus alone and mixed viral-bacterial/fungal groups. The mixed viral-bacterial/fungal group had significantly poorer survival rates compared to the virus group in hospital (A) or in the follow-up period (B). HR, hazard ratio.
