Abstract

In Ethiopia, cervical cancer is the second leading cause of morbidity and mortality from all cancers in women. Persistent infection with human papillomaviruses (HPV) plays a key role in the development of cervical intraepithelial neoplasia and invasive cervical cancer. To establish baseline data on the population-based prevalence of HPV infection and genotype distribution, we investigated cervical HPV epidemiology among rural women. This population-based study was conducted among rural women aged 30-49 years in Butajira, south-central Ethiopia. A total of 893 samples were tested from 1020 screened women. A self-sampling device (Evalyn Brush, Rovers, Oss, The Netherlands) was used and HPV presence and genotype was determined using multiplexed genotyping (MPG) by BSGP5+/6+ PCR with Luminex read out. The HPV positivity rate was 23.2% (95% CI: 23.54-22.86%) and 20.5% (95% CI = 20.79-20.21) and 10.3% (95% CI = 10.52-10.08) women were high-risk (hr- and low-risk (lr-) HPV positive, respectively. Fifty five (7.2%) of the women showed multiple hr-HPV infections. Age-specific hr-HPV infection peaked in the age-group 30- to 34 years old (58.6%) and decreased in 35-39, 40-44 and 45-49 years to 20.4%, 4.5% and 3.8% respectively. The top five prevalent hr-HPV genotypes were HPV16 (57.1%), 35 (20.3%), 52 (15.8%), 31 (14.1%), and 45 (9.6%) in the Butajira district. As a first population-based study in the country, our results can serve as valuable reference to guide nationwide cervical cancer screening and HPV vaccination programs in Ethiopia.
