Phylogenetic analysis of the hexon gene of HAdV strains identified in patients hospitalized with respiratory tract infections in Guangzhou between 2017 and 2019. The representative strains detected in this study are marked with red solid triangles. Other reference strains were gathered from previous publications (Supplementary Table 1). The phylogenetic tree was constructed with a neighbor-joining tree method and p-distance model using MEGA version 7 (http://www.megasoftware.net). Bootstrap values were calculated on 1000 replicates, and values < 70% are not shown. The tree is drawn to scale, with branch lengths measured in the number of substitutions per site
