Bottom Line: Any patient who received treatment for the same disease multiple times during 1 year was counted as one patient in that year.The sex-, age-, and region-adjusted prevalence in 2012 was 0.18%.The prevalence was highest in Busan, Jeonnam, and Gyeongnam, and there were towns with noticeably higher prevalences within these regions: Jindo (0.97%) in Jeonnam, Namhae (0.90%) in Gyeongnam, and Seo-gu (0.86%) in Busan.

ABSTRACT

Background/aims: This study compared the prevalence of hepatitis C virus (HCV) infection in the Republic of Korea and estimated the high-risk regions and towns.

Methods: National Health Insurance Service data for 8 years from 2005 to 2012 were used. The subjects of the study had visited medical facilities and been diagnosed with or received treatment for acute or chronic HCV as a primary or secondary disease according to ICD-10 codes of B17.1 or B18.2, respectively. Any patient who received treatment for the same disease multiple times during 1 year was counted as one patient in that year. To correct for the effect of the age structure of the population by year and region, the age-adjusted prevalence was calculated using the direct method based on the registered population in 2010.

Results: The overall prevalence of HCV infection among Korean adults (>20 years old) increased from 0.14% in 2005 to 0.18% in 2012. The sex-, age-, and region-adjusted prevalence in 2012 was 0.18%. The prevalence was highest in Busan, Jeonnam, and Gyeongnam, and there were towns with noticeably higher prevalences within these regions: Jindo (0.97%) in Jeonnam, Namhae (0.90%) in Gyeongnam, and Seo-gu (0.86%) in Busan.

Conclusions: The prevalence of HCV infection differs by regions as well as towns in the Republic of Korea, and is highest in Busan, Jeonnam, and Gyeongnam. The reasons for the high prevalence in these specific regions should be identified, since this could help prevent HCV infections in the future. In addition, active surveillance and treatment policies should be introduced to stop any further spread of infection in these high-prevalence regions.

Figure 1: Map of prevalence (%) of HCV infection by region in the Republic of Korea in 2012.

Mentions: According to the age and region-adjusted prevalence of HCV infection in 2012, there was no significant difference according to sex, with prevalences of 0.19% for men and 0.18% for women. However, the prevalence according to age exhibited a significant increase with increasing age, from 0.04% among those who were 20-29 years old to 0.38% among those who were 60-69 years old. According to the region, the prevalence in Chungnam was the lowest (0.06%) and the prevalence in Busan (0.35%) was approximately 6-fold higher than that in Chungnam (Table 2). Figure 1 shows a regional map of the HCV infection prevalences, and the southern region (E.g., Busan, Gyeongnam, Jeonnam, and Jeju) typically had high prevalences.
