Leprosy Cases in Korea Continue Decline, Driven by Early Detection and Treatment
Table of Contents
Despite achieving levels comparable to developed nations, South Korea remains vigilant in its fight against leprosy, with just three new cases identified in 2025 – a decrease from five the previous year. The Korea Disease Control and Prevention Agency (KDCA) released updated statistics ahead of World Hansen’s Disease Day on January 25th, highlighting ongoing efforts to eliminate the disease both domestically and globally.
Global Trends in Hansen’s Disease
Worldwide, the incidence of hansen’s disease, also known as leprosy, continues to fall, though notable challenges remain. In 2024, 172,717 new cases were reported globally, representing a 5.5% decrease from the 182,815 cases recorded in 2023. Though, Southeast Asia remains a hotspot, accounting for 72.0% of all new cases – specifically 124,295 individuals in India and Indonesia.
Korea’s Success and Ongoing Vigilance
For the past decade,Korea has maintained a remarkably low incidence of leprosy,consistently reporting fewer than 10 new cases annually. This success is attributed to effective treatment protocols and a proactive public health approach. Hansen’s disease is caused by a bacterium and is almost entirely curable with multidrug therapy, with a single dose of rifampicin rendering the disease non-infectious in 99.9% of cases.While the exact transmission route remains unclear, the skin and upper respiratory tract are believed to be primary entry points.
Targeted Screening for Foreign Nationals
Recognizing that imported cases continue to contribute to the domestic incidence, the KDCA is bolstering its screening programs for foreign nationals. The agency plans to expand free leprosy screenings from 15 to 17 times per year, and introduce “weekend mobile screening” initiatives to improve accessibility.This targeted approach aims to facilitate early detection and prompt treatment, preventing further spread.
Strengthening Medical Expertise and Patient Support
Beyond screening, the KDCA is committed to enhancing the diagnostic and treatment capabilities of medical professionals. This includes maintaining a collaborative network with dermatology and infectious disease specialists, and promoting educational opportunities through academic conferences. Moreover, the government continues to provide free leprosy medication and customized treatment plans for patients, alongside support for elderly individuals living with disabilities resulting from the disease.
A senior official stated, “The management of leprosy in Korea is at the level of developed countries, but it is indeed not over yet and the disease continues to occur through imports from overseas. Therefore, we ask for continued interest and active testing by medical staff for early detection and early treatment of leprosy.”
the World Health Organization (WHO) designated January 25th as World Hansen’s Disease Day to combat the stigma and discrimination associated with leprosy, and to raise awareness about the importance of prevention and cure. despite being a largely eradicated disease, continued vigilance and proactive public health measures are crucial to ensuring that leprosy remains a rare occurrence in Korea and around the world.
Why is this news importent? Leprosy, while rare in developed nations, continues to affect populations globally, particularly in Southeast Asia. Korea’s success in controlling the disease demonstrates the effectiveness of proactive public health measures and highlights the importance of continued vigilance.
Who is involved? The key players are the Korea Disease Control and Prevention Agency (KDCA), medical professionals (dermatologists and infectious disease specialists), patients, foreign nationals entering Korea, and the World Health Organization (WHO).
