The government of Bangladesh adopted visual inspection of the cervix with acetic acid method for cervical cancer screening in the majority of the district and sub-district hospitals. Before alternative screening methods are adopted, the prevalence of high-risk human papillomavirus (HPV) genotypes among various geographical regions must be determined. Therefore, we aimed to determine the prevalence of high-risk HPV genotypes in urban and rural areas of Bangladesh.
This cross-sectional study was carried out at Bangabandhu Sheikh Mujib Medical University, Dhaka from July 2021 to June 2022. Using a multistage sampling method, cervical samples (N = 3,856) were collected from women aged 30–49 years attending visual inspection of the cervix with acetic acid at 16 centers (eight districts and eight sub-districts). HPV tests were performed by real-time PCR amplification. Descriptive analysis and Chi-square test/Fisher’s exact test were performed for associations, and a P value <0.05 was considered significant.
Among the 3,856 women, the overall prevalence of high-risk HPV was 3.6%, with 49 (1.3%) women testing positive for HPV16, 12 (0.3%) women testing positive for HPV18, and 65 (1.7%) testing positive for other high-risk HPV genotypes. There was a significant variation in the prevalence of high-risk HPV among the divisions (P = 0.001), with the highest infection rate (7.1%) observed among women in rural Sylhet and the lowest in rural Mymensingh (0.5%). No significant difference in high-risk HPV prevalence was found between the urban and rural women, except in Mymensingh.
The prevalence of HR-HPV infection was comparatively low, with significant variation among the divisions in Bangladesh. HPV 16 infection was high in Sylhet, Barishal and Dhaka divisions and these divisions need particular attention during the planning of larger implementation research. During the introduction of the HR-HPV test for primary screening, similar attention should be given to both rural and urban populations. The rebound to higher HR-HPV prevalence among older women suggested that this group should also be targeted for screening.

The study was recently published in the Cancer Screening and Prevention .
Cancer Screening and Prevention (CSP) publishes high-quality research and review articles related to cancer screening and prevention. It aims to provide a platform for studies that develop innovative and creative strategies and precise models for screening, early detection, and prevention of various cancers. Studies on the integration of precision cancer prevention multiomics where cancer screening, early detection and prevention regimens can precisely reflect the risk of cancer from dissected genomic and environmental parameters are particularly welcome.
