Objectives Several studies have documented the HPV genotypes in the Senegalese general population. The objective was to explore the HPV genotype distribution in Senegalese FSWs in order to assess the potential relevance of currently-available vaccines. Methods Vaginal swabs samples collected as part of the National Integrated Biological and Behavioral Survey in 14 regions throughout the country were randomly selected for HPV testing using bead-based multiplex genotyping (TS-MPG). Results Among the 436 FSW samples analyzed, the overall HPV prevalence was 79.8% (N = 348), with 70.1% (N = 244) cases presenting as multiple infections. High Risk HPV genotypes affecting at least 10% of FSWs included in order of decreasing frequency: 52, 16, 35, 51, 33, 31, 18, and 45. Sixty-seven (15.4%) FSWs were HIV positive and they were significantly more affected by HPV (94% vs 77%; p < 0.01) than seronegative FSWs as well as infections with multiple genotype. Conclusion The present study indicates that FSW in Senegal experience a high burden of HPV infection with a high frequency of coinfection with HIV and multiple HPV genotypes. Public health interventions for this key population should include an earlier cervical dysplasia/cancer detection and preventative measures such as vaccination programs that must consider the HPV genotype distribution.
