Abstract
To identify genotype distribution and drug resistance in people infected by HIV-1 in Wuhan, China, 105 infected people diagnosed with HIV-1 from January to December in 2019 were involved in this study. Ninety-eight gag genes, 101 PR genes, and 98 RT genes were successfully amplified. The phylogenetic analysis results showed that CRF01_AE (38.2%) and CRF07_BC (35.3%) were the two dominant genotypes, followed by CRF55_01B (6.9%), CRF59_01B (2.0%), B (2.0%), B' (2.0%), CRF08_BC (1.0%), CRF80_0107 (1.0%), and unique recombinant form (URF) (11.8%). Most URFs were the recombinants between CRF01_AE and CRF07_BC or CRF07_BC and CRF55_01B. Among the 93 subjects of antiretroviral therapy (ART)-naive, transmitted drug resistance against non-nucleoside reverse transcriptase inhibitors (NNRTIs) was 23.9%, of which V179D/E was the most frequent mutation, accounting for 18.2%. Among the 12 subjects of ART-experienced, drug resistance to first-line regimens developed severely.
