Abstract
CRF01_AE and CRF07_BC are predominant circulating HIV-1 subtypes in China. In this study, we report two novel HIV-1 CRF01_AE/CRF07_BC recombinant forms isolated from one man who has sex with men (MSM) (BDD027) and one mother-to-child transmission (MTCT) case (BDL123) in Baoding City, Hebei Province, China. The recombination breakpoint analysis showed that the recombination pattern of the near-full-length genome of BDD027 consisted of two CRF07_BC fragments inserted into a CRF01_AE backbone, while the recombination pattern of the near-full-length genome of BDL123 consisted of one CRF01_AE fragment inserted into a CRF07_BC backbone. This study demonstrates the importance of strengthening the monitoring of HIV-1 molecular epidemiological characteristics and emphasizes the urgent need to reduce the HIV-1 epidemic among MSM and MTCT populations in China.
