NEWS RELEASE
WHO validates Mauritania for eliminating trachoma as a public health problem [https://www.who.int/news/item/19-05-2025-who-validates-mauritania-for-eliminating-trachoma-as-a-public-health-problem]
19 May 2025–Nouakchott, Brazzaville, Geneva–The World Health Organization (WHO) has validated Mauritania as having eliminated trachoma as a public health problem, making it the seventh country in WHO’s African Region to achieve this significant milestone. The validation certificate was received by Honorable Abdallahi Sidi Mohamed Wedih, Minister of Health and Aïcha Vall Vergès, Ambassador of Mauritania to Switzerland at the Seventy-eighth World Health Assembly.
“I congratulate the government and the people of Mauritania for this achievement,” said Dr Tedros Adhanom Ghebreyesus, WHO Director-General. “This is another example of the incredible progress we have made against neglected tropical diseases and gives hope to many other nations still fighting against trachoma that they too can eliminate this disease.”
Mauritania has a long history of a fight against trachoma that dates back to the 1960s. However, it was not until early 2000 that the country conducted population-based epidemiological surveys to map trachoma with the support of the Organization for the Prevention of Blindness (OPC), the Institute of Tropical Ophthalmology of Africa (IOTA) and WHO. Trachoma control activities were integrated into the National Programme for the Fight against Blindness at the Ministry of Health.
Mauritania implemented the WHO-recommended SAFE strategy to eliminate trachoma with the support of partners. These activities included provision of surgery to treat the late blinding stage of the disease, conducting mass administration of antibiotic treatment with azithromycin donated by Pfizer through the International Trachoma Initiative, carrying out public awareness campaigns to promote facial cleanliness and personal hygiene as well as improvement in access to water supply and sanitation.
“Eliminating trachoma is a landmark victory for public health in Mauritania,” said Dr Charlotte Faty Ndiaye, WHO Representative in Mauritania. “This success reflects the strong leadership and commitment of the Government, supported by the dedication of health workers, communities, and partners, with the guidance and support of WHO. We will remain vigilant and support the country to preserve this success and protect those most at risk from trachoma.”
Trachoma is the second neglected tropical disease to be eliminated in Mauritania. In 2009, the country had already been certified free of dracunculiasis (Guinea-worm disease) transmission. Globally, Mauritania joins 21 other countries that have been validated by WHO for having eliminated trachoma as a public health problem. These are Benin, Cambodia, China, Ghana, India, Iraq, Islamic Republic of Iran, Lao People’s Democratic Republic, Malawi, Mali, Mexico, Morocco, Myanmar, Nepal, Oman, Pakistan, Saudi Arabia, Gambia, Togo, Vanuatu and Viet Nam. These countries are part of a wider group of 55 countries that have eliminated one or more neglected tropical diseases.
WHO is supporting Mauritania’s health authorities to closely monitor communities where trachoma was previously endemic to ensure there is no resurgence of the disease.
Disease prevalence
As of April 2024, trachoma remains a public health problem in 37 countries with an estimated 103 million people living in areas requiring interventions against the disease. Trachoma is found mainly in the poorest and most rural areas of Africa, Central and South America, Asia, the Western Pacific and the Middle East. The African Region is disproportionately affected by trachoma with 93 million people living in at-risk areas in April 2024, representing 90% of the global trachoma burden.
Significant progress has been made in the fight against trachoma over the past few years and the number of people requiring antibiotic treatment for trachoma in the African Region fell by 96 million from 189 million in 2014 to 93 million as of April 2024, representing a 51% reduction.
Following Mauritania’s success, there are now 20 countries in WHO’s African Region that are targeting trachoma elimination.
Note to editors
Trachoma is a neglected tropical disease. It is caused by infection with the bacterium Chlamydia trachomatis, which spreads from person to person through contaminated fingers, fomites and flies that have come into contact with discharge from the eyes or nose of an infected person. Environmental risk factors for trachoma transmission include poor hygiene, overcrowded households, and inadequate access to water and sanitation.
Elimination of trachoma as a public health problem is defined as: (i) a prevalence of trachomatous trichiasis “unknown to the health system” of
