Chile is the first country in South America to receive World Health Organization validation for eliminating dog-transmitted rabies as a public health problem.

The WHO announced the validation on Monday, recognizing more than five decades of prevention work and Chile’s ability to keep transmission from returning.
Chile’s last reported human rabies case transmitted by a dog occurred in 1972, according to WHO. Since then, the country has maintained vaccination, surveillance, laboratory testing and post-exposure treatment systems designed to stop new infections.
What the validation means
WHO validation is not simply a declaration that recent cases are absent. Countries must submit evidence showing sustained interruption of dog-mediated transmission and demonstrate that public-health systems can detect and respond if the virus is reintroduced.
Chile submitted a technical dossier that was reviewed by an independent international expert group convened through the Pan American Health Organization and WHO. The review examined surveillance, laboratory capacity, animal vaccination, access to post-exposure prophylaxis and emergency response readiness.
The national program includes free mass vaccination campaigns for dogs and cats, monitoring of rabies circulation in animals, community education and treatment for people who may have been exposed through bites, scratches or infected saliva. Chile has also expanded surveillance and preventive vaccination in higher-risk border areas.
Why it matters
Rabies is preventable, but it is almost always fatal once clinical symptoms appear. Timely wound care, vaccination and, when medically indicated, rabies immunoglobulin can prevent illness after exposure.
WHO says human cases of dog-mediated rabies across the Americas have fallen by more than 98% since 1983. The disease still causes tens of thousands of deaths globally each year, primarily in Asia and Africa, making Chile’s result a significant example of sustained prevention rather than a reason to relax controls.
The achievement also illustrates the “One Health” approach, which coordinates human, animal and environmental health programs. Because dogs are the source of most human rabies transmission worldwide, vaccinating animals and maintaining rapid access to care for people work together.
What happens next
Validation requires continued vigilance. Chile will need to maintain surveillance, vaccination and rapid-response capacity, particularly in areas where infected animals could cross borders or where wildlife reservoirs remain a concern.
