Phylogenetic analysis and transmission networks of genotype 1a- (A), genotype 1b- (B), genotype 3a- (C), genotype 3b- (D), and genotype 6a-infected (E) individuals. A phylogenetic tree was constructed in PhyML 3.0 using the maximum likelihood method based on the NS5B region. The nucleotide substitution model was GTR + G + I. In the circle trees, the red lines with red dots represent samples within clusters, the black lines with black dots represent samples not within clusters, and the black lines without dots represent reference sequences. In the transmission networks, various regions in Guangdong were colour coded. Different shapes represent different risk groups: circle: blood transfusion; square: heterosexual (HET); triangle: injection drug user (IDU); arrowhead: men who have sex with men (MSM)
