Abstract
A wide variety of HIV-1 recombinants are constantly discovered in China. Comprehensively monitoring the genetic diversity of HIV-1 is very essential for understanding the molecular epidemiology and controlling the spread of the HIV-1 epidemic. In this study, we presented a novel HIV-1 unique CRF01_AE/C recombinant (19YA001) isolated from a female patient infected HIV-1 through heterosexual transmission in Yan'an city, Shaanxi province. The near full-length genome analyses showed 19YA001 was divided into two CRF01_AE and one C segments by two breakpoints observed in the vif/vpr region. To date, this is the first report revealing the characteristic of HIV-1 subtype in Yan'an city. And this unique recombinant strain might imply that the genetic diversity of HIV-1 in Yan'an city is complex. However, the sample size is too small. Further larger studies of HIV-1 molecular epidemiology are urgently needed to provide a better understanding of HIV-1 diversity and transmission in this region.
