Timor-Leste has officially eliminated trachoma as a public health problem, marking a major achievement in the global fight against one of the world’s leading infectious causes of preventable blindness.

The World Health Organization validated the country’s achievement on 3 September 2026, recognising years of work involving government programmes, health workers, communities and international partners.

Trachoma, caused by repeated infection with the bacterium Chlamydia trachomatis, mainly affects communities where access to clean water, sanitation and basic hygiene services is limited. Without treatment, repeated infections can cause scarring inside the eyelid, leading to eyelashes turning inward and damaging the cornea. In severe cases, this can result in permanent blindness.

A Long-Term Public Health Effort

Timor-Leste’s progress was built through a combination of disease surveillance, community-based interventions and improvements in living conditions.

The country implemented the WHO-recommended SAFE strategy, a comprehensive approach that combines surgery for advanced disease, antibiotic treatment and environmental improvements.

Antibiotic distribution campaigns helped reduce infections, while health education programmes encouraged communities to adopt behaviours that limit transmission. Improvements in access to water and sanitation also played an important role in reducing the conditions that allow trachoma to spread.

The success required cooperation between national health authorities, local communities and international organisations working together over many years.

Protecting Communities from Blindness

Trachoma remains a significant health challenge in some parts of the world, particularly in remote and underserved communities. The disease is closely linked to poverty, limited healthcare access and inadequate sanitation.

Eliminating trachoma as a public health problem does not mean that every individual case has disappeared. Instead, it means the country has reached the WHO thresholds showing that transmission has been reduced to a level where it no longer represents a major public health threat.

Continued monitoring remains important to ensure that progress is maintained and that any potential return of the disease is detected quickly.

Part of a Global Achievement

Timor-Leste’s success contributes to a broader international effort to eliminate neglected tropical diseases.

Trachoma has historically affected millions of people, particularly in regions with limited resources. Over recent decades, global programmes have helped reduce the number of people at risk through improved treatment, prevention and healthcare access.

The achievement also demonstrates the importance of combining medical interventions with wider social improvements. Treating infections alone is not enough; sustainable progress depends on clean water, sanitation, education and strong local health systems.

A Health Milestone for Timor-Leste

The elimination of trachoma represents an important milestone for Timor-Leste’s public health system. It shows how coordinated action and long-term investment can overcome diseases that once caused widespread suffering.

The country’s experience highlights the value of community participation and preventive healthcare in addressing infectious diseases. Maintaining surveillance and continuing improvements in hygiene and sanitation will remain essential to protect future generations.

Timor-Leste’s achievement adds to the growing number of countries that have successfully eliminated trachoma as a public health problem, demonstrating that sustained efforts can bring measurable progress in the fight against preventable blindness.
