RSV (95/149; 63.8%), HMPV (17/28; 60.7%), and INF (31/52; 59.6%) were mostly detected in specimens with single viral infection, whereas HPV (1/1; 100.0%), HEV (6/8; 75.0%), HAV (38/60; 63.3%), HBoV (13/22; 59.1%), and HRV (34/62; 54.8%) were mostly detected in specimens with two or more viral infections (Figure 2A).
