Human Papillomavirus Infection in genital Women in four regions of Senegal

El Hadji Seydou Mbaye

Introduction: Cervical cancer is the most frequent cancer among women in Senegal. However, there are few data concerning the HPV types
inducing neoplasia and cervical cancers and their prevalence, in the general population of Senegal
Aims: The aim of this study is to determine the prevalence of HPV infection in Senegalese women aged from 18 years and older.
Materials and methods: A study was performed on 498 cervix samples collected from healthy women aged 18 and older in Dakar. 438 other
samples were collected from three other regions, Thiès, Saint Louis and Louga. The samples were screened for 21 HPV genotypes using an HPV
type-specific E7 PCR bead-based multiplex genotyping assay (TS-MPG) which is a laboratory-developed method for the detection of HPV.
Results: The prevalence for pHR/HR-HPV in the region of Dakar was 20.68%. HPV 52 (3.21%) was the most prevalent HPV type, followed by HPV
16 (3.01%) and HPV 31 (3.01%). In the regions of Thiès, Louga and Saint Louis, the prevalence for pHR/HR-HPV was 29.19%, 23.15% and 20%,
respectively
Conclusion: The study revealed the specificity of the HR-HPV prevalence in Dakar and other regions of Senegal. The patterns differ from the one
observed in the other regions of the world and rise the issue of the development of vaccination program in the country. Such a program should take
into account the real HPV prevalence for an effective protection of HPV-associated diseases.
