Figure 1. RSV seasonality in Beijing.
The average percentage of RSV-positive cases per month among the tested cases in Beijing from March 2015 to February 2019. Gray bars denote the tested cases per month, blue bars denote the RSV-positive cases per month, and the brown line denotes the average percentage of RSV-positive cases per month among the tested cases. B) Average proportion of RSV-positive cases per month among the total RSV-positive cases in Beijing from March 2015 to February 2019. C) RSV detection rate by month in Beijing from March 2015 to February 2019. The bars represent the RSV detection rate per month. Blue denotes RSV group A, orange denotes RSV group B, gray denotes untyped RSV. RSV, respiratory syncytial virus.
Figure 2. Distribution of RSV infections by age group in Beijing from March 2015 to February 2019. A) RSV detection rate by age group. The bar represents the RSV detection rate per age group. Blue denotes RSV group A, orange denotes RSV group B, and gray denotes untyped RSV. RSV, respiratory syncytial virus. B) Proportion of RSV-positive cases per new-age group (9 age groups were combined into 4 new-age groups).
Figure 3. RSV detection rates andproportions of RSV subgroups by age group and illness severity in Beijing from March 2015 to February 2019. A) RSV detection rate by age group and illness severity. The bar represents RSV detection rate per age group and illness severity. B) Proportion of RSV groups per age group and illness severity. Blue denotes RSV group A, orange denotes RSV group B, and gray denotes untyped RSV. RSV, respiratory syncytial virus. AURTI, Acute upper respiratory tract infection. NSCAP, non-severe community-acquired pneumonia. SCAP, severe community-acquired pneumonia.
Figure 4. Co-existing pathogens identified in RSV-positive cases. The blue bars denote the positive cases of co-existing pathogens identified in RSV-positive cases. The orange line denotes the positive rates of co-existing pathogens identified in RSV-positive case (the data are represented in the second Y-axis). Here, AdV denotes adenovirus, CoV coronavirus, Flu influenza A or B virus, HMPV human metapneumovirus, HRV human rhinovirus, PIV parainfluenza virus, RSV respiratory syncytial virus, HBoV human bocavirus, EV enterovirus, MP M. pneumoniae , and CP Chlamydophila pneumoniae .
