Popis: For this study, 50 HIV-1 plasma samples of recently infected men who have sex with men (MSM) were amplified and sequenced. Multiple subtypes were identified by phylogenetic analyses of HIV-1 gag, env, and pol gene regions, including CRF01_AE (56.0%), CRF07_BC (30.0%), subtype B (12.0%), and unique recombinant forms (URFs, 6.0%). CRF01_AE was the most frequent genotype in the epidemic. Three recombination patterns of URFs were identified: 01BC, 01B, and 01C. The rate of HIV-1 transmitted drug resistance (TDR) mutation (M46L) was 2.08% (1/48). URFs and TDR first identified in this study suggest that HIV-1 prevalence is more and more complicated, and HIV-1 drug-resistant strains have begun to spread among at risk populations in Hebei. Our findings can provide vital information for an efficient surveillance system and strategic HIV prevention and control measures in China by revealing the evolutionary status and HIV-1 TDR of HIV-1 strains among recently infected MSM in Hebei Province.
