Abstract:

Background: The epidemiology of human papillomavirus (HPV) infection and the pattern of HPV genotype distribution are parameters needed to assess the risk of cervical cancer. Oncogenic HPV types are well-known pathogen for lower genital tract neoplasias, representing the primary cause of cancer death in Africa and the second in Cameroon. This study was conducted to identify the various genotypes particularly the high-risk HPV types in normal and abnormal cervical cytology from women in Yaoundé, Cameroon.

Methodology: This was a hospital-based, analytical cross-sectional study carried out on 226 symptomatic women wherein cervico-vaginal samples were obtained during gynaecological examination for Pap smears, HPV-DNA and genotype detection with linear array HPV strip, conducted from November 2019 to January 2021.

Abstract:

Background: Human papillomaviruses (HPVs) are non-enveloped, double-stranded DNA viruses and most women in the world are probably infected with at least one type of the virus during their sexual life. Oncogenic HPVs are predominantly sexually-transmitted pathogens and several high-risk types are associated with nearly all cases of cervical cancer worldwide. In view of paucity of data on the prevalence and distribution of various high risk HPV subtypes, this study was carried out to provide evidence based local data for cervical cancer preventive programs within this region.

Methodology: This was a descriptive cross-sectional study involving 145 consenting women living in Ugbegun rural community of Edo central senatorial district, Edo State, Nigeria. Informed consent of each participant was obtained and socio-demographic information collected through interviewer-administered collection tool. Cervical swab sample was collected using the female cervical cell collection kit for HPV DNA testing. HPV DNA was detected by the Hybribio 21 HPV Geno array test kit which uses polymerase chain reaction (PCR) amplification and flow through hybridization assay. Summary statistics were presented as mean, standard deviation, median, frequency and proportions as appropriate using the Statistical Package for the Social Sciences (SPSS) version 22.0. Association of sociodemographic characteristics of the women with HPV prevalence was done using the ‘t’ test, with p value less than 0.5 considered statistical significance.
