For millions of people living in impoverished tropical regions, the loss of sight is not always the result of aging or genetics, but of a preventable infection. Trachoma, a painful and debilitating disease, has long been the leading infectious cause of blindness worldwide. For Algeria, the fight against this condition was not a sprint, but a century-long marathon of public health mobilization.
The World Health Organization (WHO) has officially validated Algeria as having eliminated trachoma as a public health problem. This milestone marks Algeria as the 10th country in the WHO African Region and the 29th globally to achieve this status. The validation is more than a statistical victory; it represents the liberation of thousands of citizens from the threat of permanent visual impairment.
As a physician, I have seen how “neglected” diseases often remain invisible to the global North until they reach a crisis point. Trachoma is a textbook example of such a condition. Caused by the bacterium Chlamydia trachomatis, the disease spreads through direct contact with infected eye discharge via hands, clothing, or the flies that frequent contaminated areas. While the initial infection may seem minor, repeated bouts lead to a devastating cycle of scarring on the inner part of the upper eyelid.
The endgame of untreated trachoma is a condition known as trachomatous trichiasis (TT). In this stage, the scarred eyelid turns inward, forcing the eyelashes to rub directly against the eyeball. This creates a constant, agonizing sensation of grit in the eye, eventually scratching the cornea to the point of opacity and total blindness. Globally, the disease remains endemic in 30 countries, leaving approximately 1.9 million people blind or visually impaired and placing 97 million people at risk.
The SAFE Strategy: A Four-Pronged Attack
Algeria’s success was not accidental. The country adhered strictly to the WHO-recommended “SAFE” strategy, a comprehensive public health framework designed to break the cycle of transmission and treat existing cases. This approach recognized that medicine alone cannot solve a problem rooted in environmental poverty.
| Component | Action Taken | Public Health Goal |
|---|---|---|
| Surgery | Correcting trachomatous trichiasis (TT) | Preventing immediate blindness |
| Antibiotics | Mass administration of treatment | Clearing the bacterial reservoir |
| Facial Cleanliness | Hygiene awareness campaigns | Reducing transmission via contact |
| Environmental Change | Improving water and sanitation | Eliminating breeding grounds for flies |
By integrating these four pillars, Algeria addressed both the biological cause of the disease and the social determinants that allow it to thrive. The provision of free surgery for those in the blinding stage ensured that the most vulnerable were not left behind, while mass antibiotic distribution lowered the overall prevalence of the bacteria in the community.
A Century of Public Health Mobilization
The road to elimination began long before the current WHO validation. Algeria’s commitment dates back to 1909 with the establishment of the Pasteur Institute of Algeria. Following independence, the mission was carried forward by Algerian physicians, most notably Professor Mohamed Aouchiche, who integrated the fight against trachoma into the broader national health agenda.
A pivotal shift occurred in 1974, when Algeria established a national public healthcare system that provided services to patients free of charge. This removal of financial barriers was essential for reaching rural and marginalized populations who otherwise would have suffered in silence.
To cross the finish line, the government launched a targeted three-year acceleration strategy between 2013 and 2015. This effort focused on 12 southern provinces (wilayas) where the disease remained most stubborn: Adrar, Laghouat, Biskra, Béchar, Tamanrasset, Ouargla, El Bayadh, Illizi, Tindouf, El Oued, Naama and Ghardaïa. By deploying a National Expert Committee and conducting rigorous, door-to-door screenings, health officials ensured that no single case of trachomatous trichiasis remained untreated.
The Broader Impact on Neglected Tropical Diseases
Trachoma is part of a group of 21 conditions known as neglected tropical diseases (NTDs). These diseases primarily affect the world’s poorest communities, creating a cycle of poverty and illness. When a parent or child loses their sight to trachoma, the economic impact is profound, leading to lost livelihoods and increased dependency.
“Trachoma devastates individuals and communities profoundly,” said Dr. Mohamed Janabi, WHO Regional Director for Africa. “The milestone by Algeria is a major achievement that transforms the health and well-being of children, women and entire families.”
With this validation, Algeria becomes the 62nd country globally and the 23rd in the WHO African Region to eliminate at least one NTD. The country’s success is attributed to a robust school health system and an expansive health information network that allows for the rapid identification of new cases.
Professor Mohamed Seddik Ait Messaoudene, Algeria’s Minister of Health, described the achievement as a “collective victory” and the fruit of nearly fifty years of national mobilization. He emphasized that the success was grounded in “equitable access to care and the improvement of living conditions.”

The work does not end with validation. The WHO continues to support Algeria in maintaining strict surveillance to ensure there is no resurgence of the bacterium in previously endemic areas. The next phase of the national strategy focuses on the “post-validation period,” utilizing the existing health information system to monitor population health and maintain the standards of water and sanitation that made this victory possible.
