The molecular epidemiologic profile of HIV-1 in Suriname was determined through protease (PR) and reverse transcriptase (RT) sequences obtained from HIV-1 strains collected from 100 drug-naive HIV-1-infected persons. Subtype determination revealed that most viruses were of subtype B (94.9%) in both PR and RT genomic regions, followed by B/D recombinants (5.1%). Analysis of drug resistance mutations showed only one transmitted dug resistance mutation (TDRM) (V75M) in a single strain. The genetic data obtained can serve as a baseline for Suriname to monitor emerging mutations. This study reveals that the HIV-1 epidemic in Suriname is still characterized by a low TDRM rate (1%) and a low level of subtype diversity. However, both genes display a high genetic polymorphism. This high polymorphism may ultimately lead to drug resistance. Continuous monitoring of the baseline resistance is therefore a prerequisite to safeguard effective long-term treatment for people living with HIV-1 in Suriname.
