WHO, together with the Pan American Health Organisation (PAHO), congratulates Chile for becoming the first country in the Americas – and the second globally – to be officially verified as having eliminated leprosy disease.
Leprosy (Hansen disease) was historically recorded in Chile at the end of the 19th century on Rapa Nui (Easter Island). The disease was limited in mainland Chile, with sporadic introductions, contained through isolation and treatment measures in the Island, where the last secondary cases were managed by the late 1990s.
Since then, Chile has not reported any locally acquired case of leprosy for more than 30 years, with the last locally acquired case detected in 1993. However, the disease was never removed from the country’s public health agenda; it has remained a notifiable condition, monitored through mandatory reporting, integrated surveillance, and continuous clinical readiness across the health system.
“This landmark public health achievement is a powerful testament to what leadership, science, and solidarity can accomplish,” said Dr Tedros Adhanom Ghebreyesus, WHO Director-General. “Chile’s elimination of leprosy sends a clear message to the world: 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 verification recognises more than three decades of sustained public health action, robust surveillance, long-term political commitment, and a health system that has remained vigilant even in the absence of local transmission.
“Chile’s achievement demonstrates that eliminating leprosy is achievable and requires building strong systems that can detect, respond to, and provide comprehensive care for people affected by the disease, including those living with chronic disabilities,” said PAHO Director Dr Jarbas Barbosa. “Being the first country in the Americas to be confirmed as eliminating leprosy sends a powerful message to the Region – that diseases strongly linked to groups living in vulnerable conditions can be eliminated, contributing to interrupt the vicious circle between disease and poverty.”
