5 March 2026 (Navroze Bureau) : In a major public health milestone, Chile has become the first country in the Americas to eliminate leprosy as a public health problem, according to verification by the World Health Organization.
WHO confirmed that Chile has successfully reduced leprosy prevalence to below the threshold defined for elimination, marking a significant achievement in disease control and healthcare delivery. The verification follows years of sustained surveillance, early diagnosis efforts, and free access to multidrug therapy for affected individuals.
Leprosy, also known as Hansen’s disease, is a chronic infectious disease caused by bacteria that primarily affects the skin, peripheral nerves, and mucous membranes. While curable with timely treatment, delayed diagnosis can lead to permanent disability and stigma.
Health authorities in Chile attributed the achievement to strengthened primary healthcare systems, improved disease monitoring, and consistent public awareness campaigns. Officials emphasized that elimination does not mean zero cases, but rather that the disease is no longer a widespread public health threat.
WHO praised Chile’s commitment to universal healthcare access and robust epidemiological tracking. The agency noted that sustained vigilance will remain essential to prevent re-emergence and to ensure early detection of any new cases.
Public health experts say Chile’s success could serve as a model for other nations in the region where leprosy remains endemic. Global efforts continue under WHO’s strategy to achieve zero transmission and zero disability from the disease.
The milestone underscores the impact of coordinated public health policies, community outreach, and international cooperation in tackling neglected tropical diseases.
Summary
Chile has become the first country in the Americas to eliminate leprosy as a public health problem, with WHO verification highlighting sustained surveillance, early treatment, and strong healthcare systems.
