The extensive genetic diversity of HIV-1 is a major challenge for the prevention and
treatment of HIV-1 infections. Subtype C accounts for most of the HIV-1 infections in the …

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 …

The phylogeographic history of the Brazilian HIV-1 subtype C (HIV-1C) epidemic is still
unclear. Previous studies have mainly focused on the capital cities of Brazilian federal …

The high incidence of AIDS cases and the dominance of HIV-1 subtype C infections are two
features that distinguish the HIV-1 epidemic in the two southernmost Brazilian states (Rio …

Recent studies have demonstrated an increased prevalence of human immunodeficiency
virus type 1 (HIV1) subtype C in southern Brazil. Although Santa Catarina State (SC) is …

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 …

The most prevalent HIV-1 clade in the global epidemics is C, and this clade is also
becoming important in the Brazilian epidemics. In this study, we characterized HIV-1 subtype …

Human immunodeficiency virus (HIV) clades B and C account for more than 60% of the HIV-
1 infections worldwide. In this paper, we describe the profiles of patients infected with …

Abstract Information on human immunodeficiency virus (HIV) molecular epidemiology is
required to verify HIV/AIDS (acquired immune deficiency syndrome) epidemic dynamics in …

Previous studies indicate that the HIV-1 subtype C epidemic in southern Brazil was initiated
by the introduction of a single founder strain probably originating from east Africa. However …
