Human adenoviruses (HAdVs) are prevalent in patients with respiratory infections, in which recombination has important implications for viral detection and pathogenicity. However, less HAdVs recombination was reported in Qinghai plateau. In this study, we obtained an HAdV-C strain (QH-1665/2018) isolated from an infant aged one month with influenza-like illness in Qinghai Province in 2018. The whole genome sequence was generated by next-generation sequencing, and compared with that of other HAdV-C strains available in public. The strain QH-1665/2018 genome is comprised of 36,014 nucleotides and encoded 36 putative proteins. Phylogenetic analysis of complete HAdV genomes and 3 major antigen genes (penton, hexon and fiber) showed that strain QH-1665/2018 was clustered into HAdV-1 [P1H1F1]. Recombination analysis based on the RDP4 package and SimPlot software showed that QH-1665/2018 was a recombinant involving HAdV-1, HAdV-2 and HAdV-5, which was then re-confirmed by phylogenetic analysis. Our results suggest that HAdV-C recombination is highly complex, should be focused on, and the epidemiological and virological surveillance should be strengthened in Qinghai Province.
