Conclusion
In summary, this study provided important virus surveillance of ARTI burden and seasonality among young children in west China. The variety of respiratory viruses detected in this study highlighted the need for a monitoring database of ARTI and its etiological pathogen among children of different ages and genders. Judging from the epidemic season of respiratory virus in our region, we infer that the infection rate of respiratory virus in 2020 may gradually increase from October, and people can take corresponding preventive measures in advance to reduce the risk of viral infection.
