ABSTRACT
Background Persistent human papillomavirus (HPV) infection is considered the primary etiological factor for invasive cervical cancer. Understanding the epidemiology of circulating potential high-risk (HR) and HR HPV strains is essential in updating epidemiological knowledge and recommendations on genotype-specific vaccination development. In Lake Victoria Basin-LVB (Kisumu and Siaya Counties, Kenya), both the HIV burden, the post-COVID-19 pandemic environment and the population growth point to the need to study the current circulating strains. This study determined the prevalence and factors associated with Potential HR/HR HPV among women attending selected reproductive health clinics in LVB. The prevalence of Potential HR/HR HPV, genotype-specific distributions, and implications to the current HPV vaccination ongoing within Kenya are discussed. Methods A cross-sectional facility-based survey made up of 434 women aged 16-68 years was carried out in two selected facilities in the Urban-Kisumu County (Jaramogi Oginga Odinga Teaching and Referral Hospital-[JOOTRH] and rural-Siaya County (Gobei Health Center). Structured questionnaires were conducted to collect participant clinical and social characteristics. Cervical specimens were collected by registered reproductive health nurses and HPV genotyping was carried out using RIATOL HPV genotyping qPCR assay. Descriptive statistics followed by logistic binary regression was done using R version 4.3.2 Results The overall prevalence of potential HR/HR HPV among women attending the selected reproductive health clinics was reported at 36.5% (158/434). Specifically, in the rural setting, Gobei Health Center, the prevalence was 41.4% (41/99) while in the urban setting-JOOTRH, it was 34.6% (117/335). The most prevalent potential HR/HR HPV are 52, 67, 16, 31, 39, 45, and 31 for both HIV-positive and negative women and either in rural-Gobei Health Centre and Urban-JOOTRH. In this study, HIV status was not associated with potential HR/HR HPV among women attending. Age was the main factor associated with HPV infection among HIV-positive and negative women attending the selected reproductive health clinics in rural-urban Lake Victoria Basin, with women between the age of 30-39 having the highest risk (AOR=0.3, CI:0.2-0.7, p<0.001). Conclusion In both rural and urban regions, potential HR/HR HPV infection among individuals attending reproductive health clinics at the selected facilities remains common. The study identifies the need for effective implementation and clinical follow-up process of cervical cancer control program in the Lake Victoria Basin.
