The World Health Organization has formally recognized Timor-Leste as free of trachoma as a public health problem, a milestone that completes the elimination of this blinding infection across the WHO-defined Southeast Asia region. For communities across the region, that recognition marks a major shift in infectious-disease risk and in the capacity of local health systems to spot and treat cases rapidly.
Beyond the island nation’s border, the declaration reduces the number of people living under meaningful risk from trachoma to a fraction of what it once was — a change that public-health leaders say moves the global effort closer to the WHO’s 2030 goal for ending trachoma worldwide.
Why Timor-Leste’s certification matters for regional public health

Trachoma is the world’s leading infectious cause of blindness. Repeated infections with the bacterium Chlamydia trachomatis can scar the inside of the eyelid, causing the eyelashes to turn inward (trichiasis) and eventually damaging the eye. The disease disproportionately affects communities with limited access to clean water, sanitation, and basic health care.
WHO’s certification signals two things:
- Trachoma transmission has fallen below levels that require targeted public-health interventions in Timor-Leste.
- The country’s health system has the surveillance and clinical capacity to identify, investigate, and manage any future cases.
How authorities proved trachoma was no longer a public health problem
WHO validation follows detailed, long-term evidence gathering and review. Between 2015 and 2017, health teams conducted focused examinations — including screening children on Atauro Island, inspecting patients at ophthalmic clinics around the country, and carrying out door-to-door searches in communities. Those early investigations found no confirmed cases requiring a public-health response.
Timor-Leste reinforced that initial work with broader surveys. In 2025, health officials tested 4,949 specimens from children aged 1–5 across all 13 municipalities and found no sign of active transmission that would trigger trachoma-specific programs. That data package, together with documented surveillance systems and clinical services, formed the basis for WHO’s decision.
Methods used in the surveys and surveillance
- Population-based sampling of young children, the group most likely to show active infection.
- Clinic-based screening of eye patients to detect trichiasis and other advanced disease.
- Household-level case-finding in areas with previous concerns or limited access to services.
- Laboratory testing of samples to confirm absence of the causative bacteria at intervention thresholds.
Causes, risk factors, and prevention strategies that ended trachoma transmission
Trachoma thrives where poverty limits safe water, sanitation, hygiene (WASH) and access to basic medical care. Control and elimination rely on a combination of actions summarized by the SAFE strategy:
- Speedy antibiotic treatment to cure active infection (A).
- Facial cleanliness through improved hygiene and access to water (F).
- Environmental improvements such as sanitation to reduce fly vectors and transmission (E).
- Surgery for advanced cases to correct trichiasis and prevent blindness (S).
Investments in WASH, routine surveillance and integrated eye health services were essential to Timor-Leste’s progress, public-health officials said.
Regional progress: the path to a trachoma-free Southeast Asia
Southeast Asia’s elimination achievement is the result of years of coordinated campaigns, surveillance upgrades and health-system strengthening across many countries. Key milestones include:
- Lao PDR: validated in 2017
- Nepal: validated in 2018
- Myanmar: validated in 2020
- India: validated in 2024
- Additional countries — including Vietnam, Cambodia, Bangladesh, Sri Lanka, Maldives, Bhutan and Thailand — had previously achieved elimination status.
WHO leaders reflect on leadership and lessons for global elimination
WHO Director-General Dr. Tedros Adhanom Ghebreyesus described Timor-Leste’s certification as a key step toward the global elimination target for 2030, congratulating the country for reaching a milestone that benefits millions across the region. At the WHO Southeast Asia Regional Office, Dr. Nilesh Buddha emphasized how national leadership, high-quality evidence and the integration of services can yield lasting gains for communities.
Health experts point to one clear operational lesson: integrating surveillance across diseases lets limited resources produce bigger health returns, strengthening the routine systems that detect and respond to outbreaks and chronic problems alike.
