The HIV-1 has evolved swiftly and the scenario of HIV-1 genetic diversity is constantly
changing. In South America, recombinant forms of subtypes B, F1, and BF1 have historically …

HIV-1 has diversified into several subtypes and recombinant forms that are heterogeneously
spread around the world. Understanding the distribution of viral variants and their temporal …

Objective: To investigate the origin and to reconstruct the onset date of the HIV-1 subtype C
epidemic in Brazil. Design: Three independent datasets of subtype C sequences isolated …

The diverse Brazilian AIDS epidemic has reached small cities and scant molecular
information is available about the epidemic in Northern Brazil, where the incidence is …

Intersubtype recombinants classified as circulating recombinant forms (CRFs) or unique
recombinant forms (URFs) have been shown to play an important role in the complex and …

Approximately 36.7 million people were living with the human immunodeficiency virus (HIV)
at the end of 2016 according to UNAIDS, representing a global prevalence rate of 0.8%. In …

HIV-1 B is predominant in Brazil, but HIV-1 C has increasingly been reported in the south of
the country. However, many samples clustering with clade C are actually a recombinant …

Background The findings of frequent circulation of HIV-1 subclade F1 viruses and the
scarcity of BF1 recombinant viruses based on pol subgenomic fragment sequencing among …

The aim of this study was to determine the rate and risk factors of HIV-1 mother-to-child
transmission (MTCT), the timing of transmission and the transmitted subtype in a population …

Abstract HIV-1 recombination, reverse transcriptase (RT) low fidelity and high replication
rate are the drivers of variability and evolution on the global scale. Only few of these HIV-1 …
