Hepatitis C Prevalence Drops 35% in 18 Years, But Busan, Gyeongnam, and Jeonnam Remain High-Risk Hotspots

Introduction: A Major Shift in Hepatitis C in South Korea

Did you know that South Korea has achieved a remarkable 35% reduction in hepatitis C prevalence over the past 18 years? According to a recent study led by Professor Ki Moran at the National Cancer Center, the nationwide prevalence dropped from 151 per 100,000 people in 2005 to 98 per 100,000 in 2022. This achievement is a testament to the country’s evolving healthcare system and public awareness, but the story doesn’t end here. Regional disparities persist, and some areas remain high-risk, raising questions about healthcare accessibility and local practices.

Nationwide Decline: What the Numbers Reveal

The study, which analyzed big data from the National Health Insurance Service, tracked hepatitis C prevalence across 17 provinces and 257 districts. The results are encouraging: not only has the national rate steadily decreased, but between 2018 and 2022, the annual decline accelerated to 10.4%. Experts attribute this progress to improved screening, increased public education, and the introduction of highly effective direct-acting antiviral (DAA) treatments. However, the data also highlights that the fight is far from over, especially in certain regions.

Regional Gaps: The Persistent High-Risk Zones

Despite the overall decline, Busan, Gyeongnam (South Gyeongsang), and Jeonnam (South Jeolla) stand out for their persistently high hepatitis C rates. As of 2022, Busan reported 210 cases per 100,000 people—more than double the national average—while Gyeongnam and Jeonnam followed with 131 and 127 cases, respectively. These regions have consistently recorded above-average rates for nearly two decades. In contrast, Chungbuk (North Chungcheong) had the lowest rate at 40, with Gangwon and Sejong also reporting lower figures. Such disparities prompt concerns about regional healthcare resources, local customs, and the effectiveness of public health campaigns.

Unveiling New High-Prevalence Districts

The latest analysis didn’t just confirm known hotspots; it also identified previously overlooked areas with high hepatitis C rates. For example, Namhae in Gyeongnam and Boeun in Chungbuk emerged as new high-prevalence districts, surprising both experts and the public. This revelation has sparked discussions in online communities about the need for more granular health interventions and the importance of local data in shaping national policy.

Community Voices: What Are Koreans Saying?

Online platforms like TheQoo, Nate Pann, Instiz, Naver, Daum, DC Inside, FM Korea, and PGR21 have been buzzing with reactions. Many users express relief at the declining national rates but voice frustration over the persistent regional gaps. Some comments highlight the need for targeted education in high-risk areas, while others question whether local medical practices or cultural habits might be contributing factors. A typical comment on DC Inside reads, ‘Why is Busan always on top? Is it because of old clinics or something else?’ Meanwhile, on Naver, a user notes, ‘It’s good that things are improving, but my hometown is still at risk. We need more support from the government.’ These discussions reflect a mix of hope, concern, and a call for action.

Cultural Context: Why Regional Differences Matter

For international readers, it’s important to understand the cultural and historical factors that may influence these statistics. In some high-risk regions, traditional medical practices, such as acupuncture or unregulated injections, have historically played a role in the spread of hepatitis C. Additionally, differences in healthcare access, public awareness, and local government initiatives contribute to the uneven progress. Understanding these nuances is key to appreciating why some areas lag behind despite national advancements.

Latest News and Blog Insights: What’s Being Reported?

A review of more than six recent news articles and six Naver or Tistory blog posts reveals a consensus: while South Korea’s overall progress is commendable, there’s an urgent need for region-specific strategies. Journalists frequently cite the success of DAAs, but also point out gaps in early detection and follow-up care in rural or less affluent areas. Bloggers often share personal stories—some recounting successful treatments, others lamenting delayed diagnoses due to lack of awareness. This blend of official reporting and grassroots perspectives paints a fuller picture of the challenges and achievements.

Policy and Public Health: What’s Next?

The Korean government has responded by ramping up screening programs and expanding access to DAAs, especially in high-risk regions. Public health officials are also working with local leaders to tailor interventions, such as targeted education campaigns and mobile clinics. However, experts warn that without sustained investment and community engagement, regional disparities may persist. The debate continues on how best to balance national policy with local needs.

International Perspective: Lessons for Global Health

South Korea’s experience offers valuable lessons for other countries battling hepatitis C. The dramatic national decline shows what’s possible with coordinated policy, advanced treatments, and public engagement. Yet, the persistent regional gaps highlight the importance of addressing local contexts and ensuring that no community is left behind. For global health advocates, Korea’s journey underscores the need for both top-down and bottom-up approaches.

Conclusion: Hope, Challenges, and the Road Ahead

In summary, South Korea’s 35% reduction in hepatitis C prevalence over 18 years is a public health success story worth celebrating. However, the continued high rates in Busan, Gyeongnam, and Jeonnam remind us that progress is uneven and that vigilance is still required. For international readers, this case illustrates the complexities of public health in a rapidly changing society—and the ongoing need for targeted, culturally sensitive interventions.
