A. Unrooted phylogenetic tree of HIV-1 subtype A sequences from Greece (marked in light blue), AFSU* or A6 (marked in light purple), and a global reference dataset (marked in grey). Outbreak-PWID** sequences are marked in blue and PWID-imported transmissions are indicated with red. (*FSU: Former Soviet Union countries; **PWID: people who inject drugs).B. Detail of the phylogenetic tree showing the clustering patterns of sequences from PWID-imported transmissions. The scale bar indicates the number of nucleotide substitutions per site.
