Identification of Three Novel HIV-1 Second-Generation Recombinant Forms (CRF01_AE/CRF07_BC) Among Men Who Have Sex with Men in Baoding, Hebei, China
Abstract
The number of the second-generation recombinants originated from these two subtypes is significantly increasing due to co-circulating of CRF01_AE and CRF07_BC in China, especially among men who have sex with men (MSM). In this study, we reported three new unique recombinant forms (URFs) among MSM in Baoding, China. Phylogenetic and recombinant analyses based on the near full-length genome revealed these three URFs were the second-generation recombinant strains originated from CRF01_AE and CRF07_BC. Nowadays, the MSM has become a main route that causes the viral recombination. Therefore, the further epidemiological surveillance should be conducted in the MSM population to strengthen our knowledge of HIV-1 evolution and genetic diversity.
Keywords: Baoding; CRF01_AE; CRF07_BC; HIV; MSM.
