Tunisia Achieves Major Public Health Milestone: WHO Validates Elimination of Trachoma
Tunisia has reached a historic turning point in its public health journey. The World Health Organization (WHO) has officially validated that the country has eliminated trachoma as a public health problem, marking the end of a decades-long battle against a leading cause of preventable blindness.
This achievement follows years of sustained national effort, coordinated policy, and significant improvements in community health infrastructure. For Tunisia, this is not just a medical victory. it is a testament to what long-term political commitment and robust primary healthcare can accomplish.
A Victory Over Preventable Blindness
Trachoma is a devastating infectious disease caused by the bacterium Chlamydia trachomatis. It spreads through close personal contact, contaminated surfaces, and flies that carry infected eye and nose discharge. If left untreated, repeated infections can cause the eyelids to scar and turn inward, leading to permanent blindness.
“I congratulate Tunisia on this historic public health achievement,” said Dr. Tedros Adhanom Ghebreyesus, WHO Director-General. “Eliminating trachoma shows what long-term political commitment, strong primary health care and teamwork can do. Tunisia has proven that even the world’s leading infectious cause of blindness can be overcome.”
The SAFE Strategy: How Tunisia Succeeded
Tunisia’s success didn’t happen by chance. The country implemented a comprehensive response by scaling up the WHO-recommended SAFE strategy, a multi-pronged approach designed to break the cycle of transmission:
- S – Surgery: Providing surgical intervention for advanced cases to prevent blindness.
- A – Antibiotics: Using medication to clear the bacterial infection.
- F – Facial cleanliness: Promoting hygiene to reduce the spread of the bacteria.
- E – Environmental improvement: Enhancing access to water and sanitation to eliminate breeding grounds for disease vectors.
Beyond this framework, Tunisia integrated eye care into its primary healthcare and school health programs. The Ministry of Health also launched nationwide screening and treatment campaigns, working directly with communities to promote better hygiene practices.
Dr. Mustapha Ferjani, Tunisia’s Minister of Health, emphasized that the milestone reflects the dedication of entire generations. “This milestone is the result of decades of coordinated national efforts, with the dedication of generations of health-care professionals, local communities who worked tirelessly to expand access to care, strengthen prevention and improve eye health across the country,” Ferjani stated.
Understanding the Technical Definition of “Elimination”
In public health terms, “elimination” is a rigorous standard. To receive WHO validation, Tunisia had to meet specific epidemiological criteria:
- Trachomatous trichiasis (TT) prevalence: The prevalence of TT “unknown to the health system” must be less than 0.2% among people aged 15 and older.
- Trachomatous inflammation-follicular (TF) prevalence: The prevalence of TF in children aged 1–9 years must be less than 5% in every formerly endemic district.
- Surveillance systems: The country must maintain a robust system to identify and manage any new incident cases of TT.
Global and Regional Impact
Tunisia’s achievement places it in an elite group of nations leading the fight against neglected tropical diseases (NTDs). It is the 31st country in the world to be validated for trachoma elimination and the 14th country in the WHO Eastern Mediterranean Region to eliminate at least one NTD.
This success contributes to the global targets set in the WHO roadmap for neglected tropical diseases 2021–2030. While the WHO Alliance for the Global Elimination of Trachoma by 2020 (GET2020) set an earlier target, the global community remains focused on the new 2030 target date for worldwide elimination.
“This milestone stands as a strong demonstration of how science, evidence-based programming and coordinated technical support can overcome neglected tropical diseases every time and everywhere,” noted Dr. Ahmed Zouiten, Acting WHO Representative in Tunisia.

Frequently Asked Questions
What is a neglected tropical disease (NTD)?
NTDs are a group of diseases that primarily affect impoverished communities in tropical regions. They often cause significant health, social, and economic burdens, including disability and stigma.
How does Tunisia plan to prevent the disease from returning?
Tunisia has established a robust post-validation surveillance system. This includes ongoing training for health professionals and a dedicated system to detect and manage any new cases at an early stage to prevent a resurgence.
Which other countries have eliminated trachoma?
Tunisia joins a growing list of validated countries, including Algeria, Australia, China, Egypt, India, Mexico, Morocco, and many others across Africa, Asia, and the Americas.
