The World Health Organization (WHO), together with the Pan American Health Organization (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 recognizes 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.”

At the request of Chile’s Ministry of Health, PAHO and WHO convened an independent expert panel in 2025 to assess whether elimination had been achieved and could be sustained over time. The panel conducted a thorough assessment, reviewing epidemiological data, surveillance mechanisms, case management protocols, and sustainability plans. Its findings confirmed the absence of local transmission and validated Chile’s capacity to detect and respond to future cases occurring among the non-autochthonous population.

“This is very good news and a source of great pride for our country. Chile has received verification of the elimination of leprosy disease, becoming the first country in the Americas and the second globally to achieve this recognition,” said Ximena Aguilera, Chile’s Minister of Health. “This milestone reflects decades of sustained public health efforts, including prevention strategies, early diagnosis, effective treatment, continuous follow-up, and the commitment of health teams across the country. It also reaffirms our responsibility to maintain active surveillance and ensure respectful, stigma-free care for all.”

Sustained training, surveillance and holistic care in a low-incidence settingBetween 2012 and 2023, Chile reported 47 cases nationwide, none of which were locally acquired.

Chile’s integrated model ensures early detection and comprehensive care: primary care centers serve as the entry point for suspected cases, with ti
