Chile is the first country in South America to eliminate dog-transmitted rabies as a public health problem, according to a validation announced by the World Health Organization on Monday. The milestone follows more than five decades of public health prevention and surveillance, with the country’s last reported case of dog-to-human rabies occurring in 1972.
How Chile Achieved Rabies Elimination
The successful eradication campaign relied on sustained national public health policies. According to the WHO, Chile utilized extensive pet vaccination drives, door-to-door dog vaccination campaigns, and targeted measures for managing the dog population. These operational efforts were paired with community awareness and education initiatives to keep transmission rates at zero.
Chilean Health Minister May Chomali praised the joint efforts during a celebration in Santiago. Chomali noted that public policy yielded the desired results through localized work inside communities and municipalities. Those groups handle education, vaccination, and pet control directly on the ground.
Did you know? Rabies spreads primarily through the saliva of an infected animal via a bite, though the Centers for Disease Control and Prevention notes infection can also occur if saliva enters the eyes, nose, or mouth. While almost always fatal once initial symptoms appear, it is fully preventable through vaccination, effective surveillance, and prompt post-exposure prophylaxis.
Regional Progress and Global Context
The achievement in Chile contributes to a broader regional trend across the Americas. According to the WHO and the Pan American Health Organization (PAHO), human cases of dog-transmitted rabies in the region have dropped by more than 98% since 1983, leaving only a few cases reported annually today.
PAHO Director Jarbas Barbosa commended Chile for demonstrating what countries can accomplish through investments in vaccination, surveillance, and access to care. WHO Director-General Tedros Adhanom Ghebreyesus added that Chile’s success offers valuable lessons for countries working to end human deaths caused by the preventable disease. Globally, the virus still kills nearly 60,000 people every year, with most victims bitten by dogs, per WHO data.
