ABSTRACT
HIV-1 subtype C is associated with more than half of infections in southern Brazil and has been increasing in other regions of the country. In a previous study carried out in northeastern Brazil, we found a prevalence of 4.1% of subtype C. This work investigates the origin of subtype C in the state of Bahia based on five new viral sequences. The phylogenetic analysis showed that subtype C viruses found in Bahia descend from the main lineage that circulates in other Brazilian regions.
