The study aimed to analyze the detection rates and clinical features of respiratory syncytial virus (RSV) in young children hospitalized with acute lower respiratory infections (ALRI) between 2013 and 2018 at a children's hospital in Chongqing.
Out of 2,066 hospitalized children, 826 (39.98%) tested positive for RSV, with RSV-B being more common in certain years and RSV-A in others; the peak detection rate occurred during winter.
Children with RSV, especially when combined with human rhinovirus, experienced more severe symptoms such as wheezing, and the group with single RSV infections was generally younger and had more instances of severe respiratory issues compared to other groups.
