Abstract

Recombination contributes substantially to the genetic diversity of HIV-1. Here we reported a novel HIV-1 recombinant detected from a Chinese labor who had been to Uganda as an immigrant worker using nanopore sequencing. Near full-length genome (NFLG) phylogenetic analysis showed that the novel HIV-1 recombinant HIV-sd1801 stood in a distinct branch between the CRF130_A1B/CRF131_A1B and CRF50_A1D/CRF84_A1D reference sequences. Recombinant analysis showed that the NFLG of HIV-sd1801 was composed of subtypes A1, D, and K, with 19 recombinant breakpoints observed in the gag, pol, tat, rev, vpu, env, and nef regions. This is the first detection of a novel HIV-1 recombinant (A1/D/K) in immigrant workers in China, which indicated the continuous evolution of HIV-1 among this population and underscored the importance of continuous surveillance of the dynamic changes of HIV-1.
