World Health Organization officially validates Timor-Leste’s achievement in eradicating trachoma as a public health problem, bringing a long end to one of the biggest efforts to conquer the most common infectious cause of blindness in the world. This milestone was made public on early September 2006, and carries an extra special meaning as Timor-Leste was the only suspected endemic country within the WHO South-East Asia Region to be formally declared free of trachoma. The entire region is because of this now considered trachoma-free. Trachoma is transmitted by close contact with the eye and nasal discharge of infected people. Children are most vulnerable, in communities where clean water and proper sanitation are not available. Over time, repeated infections can cause scarring of the inside of the eyelid so the lashes turn inwards and rub on the eye and ultimately blind.
For many years trachoma was a persistent, but largely hidden problem in parts of Timor-Leste. By steadily reducing transmission with national initiatives and partners, following the WHO’s SAFE strategy, eventually the disease was no longer present at a level that warranted a targeted public health response as survey results. The Safe strategy has four components: surgery for the advanced stage, antibiotic treatment to eliminate infection, hygiene awareness, and an improved environment on water and sanitation.
All of these elements were applied systematically in Timor Leste as an integrated program within general primary health care and not as an isolated campaign. A robust survey performed in 2025 which sampled around five thousand specimens from young children from all thirteen municipalities, confirmed that there was no continuing transmission at a level warranting continued mass treatment.
Combined with the evidence of a capacity to detect and manage cases should they occur in the future, WHO could conduct a comprehensive validation process. Government and WHO regional office officials both highlight good leadership and reliable data as having contributed much to this. Having existing health services that extend into remote areas ensured that antibiotic provision, training in trichiasis detection and promotion of hygiene did not require separate infrastructure, producing a sustained outcome and not just an event.
The achievement by Timor-Leste is the thirty-third world-wide and fourth in the region, making it another success in which the entire region participates. The progress is reached as efforts on the target of global trachoma eradication as a public health problem by 2030 go on. But progress is varied as Africa bears a heavy disease load, each certified country is a further testament of success toward global elimination that this goal is achievable even in a resource-poor country.
For families in Timor-Leste, the consequences for children are reduced in term of increased likelihood of suffering the long-term suffering of re-infection and elderly people who faced the threat of the pain and blinding suffering are residing in the community which the disease no longer widespread. But, validation does not mean that all the work is completed. Health authorities will need to keep an eye on disease and ensure that imported cases are responded to swiftly. Systems for sanitation will continue to need to be developed to protect from the wide variety of other diseases prevalent. Systems developed for trachoma control can feed into the broader aim of improving eye health and primary health care; but the official acknowledgement is a true achievement in public health.
