Heterosexual transmission (HETE) represents the predominant method of transmission for the human immunodeficiency virus type 1 (HIV-1) in Shijiazhuang, Hebei Province, China. The number of circulating recombinant forms (CRFs) and unique recombinant forms (URFs) continues to increase in this region. In the present study, two novel URFs (TFH010919 and TFH010944) were identified, both derived from HETEs in the Shijiazhuang area. The phylogenetic and recombination breakpoint analyses conducted on the near-full-length genomes of the two novel URFs revealed that the CRF01_AE strains serve as the predominant backbones for both TFH010919 and TFH010944. TFH010919 is a second-generation recombinant form composed of CRF01_AE and CRF07_BC, whereas TFH010944 is formed by the combination of CRF01_AE and CRF68_01B. This finding indicates that HIV-1 prevalence among HETEs remains a significant concern, driven by complex sexual networks that facilitate the spread of diverse recombinant strains, providing more opportunities for the recombination of viruses. The emergence of these new URFs revealed the ongoing evolution of HIV-1 and underscores the critical need for continuous monitoring of viral diversity in Hebei Province and surrounding regions to control HIV-1 transmission within the vulnerable population and beyond.
