Maximum-likelihood phylogenetic trees of patients infected with different HIV-1 subtypes in Shaoxing city from 2019 to 2023. The phylogenetic trees based on the pol region of different HIV-1 subtypes were constructed by an approximate maximumlikehood method with IQ Tree 2.0.6 under the GTR+G+I nucleotide substitution model. Clades of different colours represent different HIV-1 subtypes and subclusters. The inner circle red colour square box represents ressistances individuals; the outer circles shows the risk group, Black colour square box represents heterosexual individuals, White colour square box represents homosexual individuals. A Maximum-likehood phylogenetic tree of CRF07_BC. B Maximum-likehood phylogenetic tree of CRF01_AE.C Maximim-likehood phylogenetic tree of other HIV-1 subtypes.
