Phylogenetic analysis of HAdV strains identified in children hospitalized with pneumonia in Guangzhou between 2013 and 2019. The maximum‐likelihood tree was generated based on nucleic acid sequences of HAdV hexon, penton, and fiber gene, respectively. Guangzhou strains are represented in different colors depending on the year of sampling. Closely related reference strains (marked with circle) including in the phylogenetic tree were used to define the phylogenetic genotype of the gene. The corresponding genotypes of other two genes were shown on the right of each terminal branch
