(148) The Prevalence and Genotype Distribution of Human Papillomaviruses in Korean

Abstract

Abstract Introduction Human papillomavirus (HPV) prevalence and genotype distribution are different between various nations and regions. Additionally, previous studies have mainly focused on HPV infection in western female and epidemiological studies of HPV infection in regional populations have been rarely reported. The lack of information on the HPV genotype distribution of the regional population in each individual country or region raises questions about the effectiveness of the current 9-valent vaccination. Objective To assess the prevalence and genotype of HPV(+) Korean and to know whether currently available 9-valent vaccine can cover the most prevalent and high risk genotype as HPV vaccine in Korean. Methods Between January 2014 to June 2022, samples of 44,065 men (Study I, M) and 564,499 females (Study II, F), who were volunteered for testing or recommended by a clinician, were tested for HPV detection and genotyping. Samples were collected swabs from the pap smear test. HPV detection and typing were conducted using the Anyplex™ II HPV 28 Detection system, which detects 19 high-risk (HR) HPVs and 9 low-risk (LR) HPVs. Results In Study I & Study II, overall prevalence were 59.7% (M), 44.3%(F), prevalence of HR were 30.6%(M), 37.5%(F) and LR HPVs were 50.1%(M), 18.3%(F), respectively. Overall HPV prevalence was higher in teens (34.1% in M and 58.3% in F) and 20s (33.8% in M and 51.9% in F) with age [Table 1]. The most prevalent genotypes of HR were 16 (5.2%), 53 (4.6%), 51 (4.2%), 52 (3.8%), 58 (3.7%), 39(3.6%) and 66(3.4%) in Study I. In Study II of Female, the most prevalent genotypes of HR were 52 (7.1%), 53 (6.2%), 58 (5.0%), 68 (4.8%), and 16 (4.3%). In Study I of 26,299 men with HPV infection, 9,259 (35.2%) had a genotype with HR; 53 (4.6%), 51 (4.2%), 39(3.6%) and 66(3.4%), which could not prevented by the 9-valent vaccine. In Study II of 211,883 females with HPV infection, 72,252 (34.1%) had a genotype with HR, 68 (4.8%), 51 (4.1%), 39 (3.8%), and 56 (3.7%) which could not be prevented by the 9-valent vaccine. Conclusions In this study, Korea male and female aged under 30 years showed a high prevalence of HR HPVs. In both Male and Female groups, a significant number of HR HPVs infections were not prevented by 9-valent vaccine. Based on this result, it is necessary to develop nation-specific HPV vaccination for Korean. Further, this approach can be applied in other countries. Disclosure No.
