A novel HIV-1 unique recombinant virus (XC2014EU20) was identified here, which was isolated from a HIV-positive man who infected through heterosexual in Sichuan, China. The near full-length genome analyses showed that the novel recombinant composed of three subtype B regions in a subtype C backbone. Different from the other CRFs and URFs, six recombinant break-points of XC2014EU20 with seven fragments were observed in the pol, vpu and nef genes, respectively. The emergence of B/C recombinant strain indicates the increasing complexity of the HIV-1 epidemic in Sichuan, China.
