To analyse the obtained SARS-CoV-2 genomes respectively derived from the infected Chinese tourist (GISAID accession ID: EPI_ISL_412974) and the Italian patient (GISAID accession ID: EPI_ISL_412973) in a phylogenetic context, a dataset of 40 available SARS-Cov-2 complete genomes from different countries was retrieved from GISAID (https://www.gisaid.org/, last access 2 March 2020; Supplementary material).
