Prevalence of Oncogenic Human Papillomavirus Genotypes among Sexually Active Women in Parakou (benin, West Africa)

Background: The genital infection due to Human papillomavirus (HPV) is considered as the most common sexually transmitted infection across the world, including high-risk oncogenic HPV (HR/HPV). Objective: This study aimed to determine the prevalence of HR/HPV genotypes among sexually active women in Parakou (Benin) in 2017. Methods: This research work was a cross-sectional descriptive study carried out in the city of Parakou (Benin), from January 15 to April 15, 2017. Sample consisted of 247 sexually active women selected through a systematic random sampling. Cervical specimens collected with swab were subject to multiplex PCR to characterize 14 HR/HPV genotypes. Results: The prevalence of HR/HPV infection was rated 32.8% [95% CI: 27.1-39.3]. All the fourteen HR/HPV genotypes investigated were detected using PCR among our study population. The most common types of HR/HPV were, in descending order, HPV45 (25.9%), HPV35 (18.5%), HPV52 (17.3%), HPV51 (16.0%) and HPV58 (14.8%). HPV16 and 18 were found out at respective proportions of 2.5% and 7.4%. Age group 20 years or less had the highest prevalence of HR/HPV infection (55.7%) followed by age group from 21 to 30 years (38.3%). Conclusion: The prevalence of HR/HPV infection is high among sexually active women in Parakou in 2017 and the most frequent HR/HPV are not those found commonly in precancerous and cancerous cervical lesions.
