El Salvador just hit a major public health milestone. The WHO has officially validated the country as having eliminated trachoma — the world's leading infectious cause of blindness — making it the first Central American nation and only the second in the Americas to earn this distinction. The achievement followed targeted community assessments from 2023 to 2026 that found zero evidence of active disease transmission.
El Salvador wipes out a blinding disease — and makes history doing it.
The World Health Organization has officially validated El Salvador as having eliminated trachoma as a public health problem, making it the first country in Central America and only the second in the Americas to reach this milestone. Trachoma, caused by the bacterium Chlamydia trachomatis, is the world's leading infectious cause of blindness and is closely tied to poverty and limited access to clean water and healthcare.
The validation came after targeted assessments conducted between 2023 and 2026 found no signs of active trachoma transmission — no disease detected in children and no advanced cases in adults. El Salvador's success was driven by a multisectoral approach combining strengthened primary healthcare, improvements in water, sanitation, and hygiene (WASH), eye health services, and strong community engagement backed by PAHO and the Government of Canada.
By the numbers:
Why it matters: El Salvador's achievement shows that even neglected tropical diseases deeply rooted in poverty can be beaten with sustained political will and community-focused health strategies — offering a replicable model for other nations racing toward the 2030 global elimination goal.
