The South American country of Chile has officially been recognized as free of leprosy after decades of consistent efforts by its healthcare system, the World Health Organization (WHO) reports.

The verification was conducted by WHO and the Pan American Health Organization, confirming that the country has completely interrupted local transmission of the disease. This makes Chile the first country in the Americas and the second in the world to achieve this status.

Leprosy, also known as Hansen’s disease, is a chronic infectious disease caused by the bacterium Mycobacterium leprae. It affects the skin, peripheral nerves, eyes, and mucous membranes of the respiratory tract. While the disease is treatable, without timely therapy it can lead to nerve damage, disability, and severe social stigma for patients.

Historically, cases in Chile were recorded as far back as the late 19th century, particularly on Rapa Nui (Easter Island). On the mainland, the disease was rare and gradually brought under control through measures such as isolation, early diagnosis, and treatment. The last case of local transmission was reported in 1993, and no new chains of domestic infection have occurred since then.

Despite the disappearance of local cases, leprosy has not been removed from epidemiological surveillance. Physicians are required to report every detected case, and the healthcare system maintains readiness for diagnosis and treatment. Between 2012 and 2023, 47 cases of leprosy were reported in the country; however, all were imported from other countries and did not lead to local spread in Chile.

Experts note that this achievement was made possible by a long-term government strategy: early detection, free treatment, continuous training of medical personnel, and a robust epidemiological monitoring system. According to specialists, Chile’s experience demonstrates that even ancient diseases that have accompanied humanity for centuries can be fully eliminated through consistent public health policies and international cooperation.
