WHO Validates Timor-Leste’s Elimination of Trachoma as a Public Health Problem

The World Health Organization announced on 3 September 2026 that it has validated Timor-Leste’s elimination of trachoma as a public health problem, following an evaluation that spanned several years. Trachoma is a bacterial eye infection that, left untreated over repeated exposures, can cause the eyelid to turn inward and scar the cornea, leading to irreversible blindness.

The Last Country in the Region

According to WHO, Timor-Leste was the final country in the WHO South-East Asia Region with suspected endemic trachoma, meaning the validation clears the disease as a public health concern across the entire region. A 2025 survey that examined 4,949 samples from children aged one to five across the country found no evidence of transmission at a level requiring a specific public health intervention, WHO said. WHO validation of elimination requires countries to sustain surveillance and low disease prevalence over an extended period, a process that typically takes several years of consistent data collection even after active transmission has stopped.

Recognition in Dili

Timor-Leste’s Minister of Health, Elia A. dos Reis Amaral, received the WHO Public Health Achievement Award from Director-General Dr Tedros Adhanom Ghebreyesus in recognition of the milestone. The award was presented during the 79th Session of the WHO Regional Committee for South-East Asia, held in Timor-Leste from 7 to 10 September 2026, a gathering that also recognised other member states for progress on separate public health goals, underscoring the region’s broader push to close remaining gaps in neglected tropical disease control.

Why It Matters

Trachoma remains one of the leading infectious causes of blindness worldwide, disproportionately affecting poorer and rural communities with limited access to clean water and sanitation. Timor-Leste’s validation reflects sustained investment in surgery, antibiotic treatment, facial cleanliness promotion and environmental improvement, the strategy WHO has promoted globally, and offers a template other countries still working toward trachoma elimination can point to as achievable.
