Chile has just made history — becoming the first country in the Americas, and only the second in the world, to be verified as having eliminated leprosy.
The World Health Organization announced the milestone this week, describing it as a 'landmark public health achievement' and 'a powerful testament to what leadership, science, and solidarity can accomplish.'
Leprosy, also known as Hansen's disease, is one of humanity's oldest documented illnesses. For thousands of years, it caused disfigurement, disability, and profound social stigma. While modern antibiotics have made it treatable since the 1980s, the disease persists in many parts of the world — with approximately 200,000 new cases diagnosed globally each year.
Chile's elimination follows decades of sustained public health efforts: prevention strategies, early diagnosis, improved treatments, and continuous follow-up care that ensured the chain of transmission was broken.
'Chile's elimination of leprosy sends a clear message to the world,' said WHO Director-General Dr Tedros Adhanom Ghebreyesus. 'With sustained commitment, inclusive health services, integrated public health strategies, early detection and universal access to care, we can consign ancient diseases to history.'
The first country to be verified as having eliminated leprosy was Jordan in September 2024. Chile's certification means that an entire continent — the Americas — now has its first leprosy-free nation.
The achievement is particularly significant because leprosy elimination requires more than just treating individual cases. It demands systematic surveillance, community education to reduce stigma, and healthcare infrastructure that reaches everyone — including marginalised populations who historically faced the greatest risk.
Chile's success proves that ancient diseases can be defeated not through a single breakthrough, but through years of patient, methodical public health work.
For the thousands of health workers whose quiet dedication made this possible, and for the patients whose suffering was prevented, this is a moment worth celebrating. 🏥
