Overview
Updated 1 hour agoTimor-Leste was the last country in Southeast Asia where trachoma, the world's leading infectious cause of blindness, still counted as a public health problem. On September 3, 2026, the World Health Organization (WHO) validated that the disease is gone, clearing the entire South-East Asia Region.
The milestone caps a 24-year global push. In 2002, 1.5 billion people were at risk of trachoma. As of March 2026, 92 million still need interventions, and the 2030 target of ending the disease worldwide is coming into view.
Why it matters
Trachoma blinds millions through preventable infection; its elimination from a whole region proves the WHO strategy can protect the 92 million people still at risk.

Historical Context
3 moments from history that rhyme with this story — and how they unfolded.
Smallpox eradication (1977–1980)
The last natural case of smallpox was recorded in Somalia in October 1977. WHO declared the disease eradicated in May 1980, making it the first — and still only — human disease ever fully eliminated.
Vaccination campaigns stopped; surveillance replaced them.
Set the template for disease elimination programs worldwide.
Timor-Leste's validation is a regional step on the same country-by-country path to global elimination.
Guinea worm (dracunculiasis) campaign (1986–present)
Guinea worm disease fell from 3.5 million cases in 1986 to fewer than a dozen in recent years. Final eradication has repeatedly slipped because the last cases sit in conflict zones with poor access.
The disease is at its lowest level ever recorded.
Shows how last-mile elimination can stall despite near-complete success.
Trachoma's remaining 29 endemic countries face the same pattern: progress is hardest where access and stability are weakest.
Polio-free certification of the Americas (1994)
The last polio case in the Americas was reported in Peru in 1991. An independent commission certified the region polio-free in 1994, requiring a high bar of surveillance evidence, not just zero reported cases.
The Americas became the first region certified polio-free.
Regional certification became the standard model for elimination proof.
WHO applied the same region-wide certification standard to trachoma, requiring Timor-Leste to document surveillance capacity for future cases.
