A Groundbreaking Prevalence Survey Conducted in Mauritania for Enhanced Sickle Cell Control

Abstract Issue/Problem Sickle cell disease is a major concern in sub-Saharan Africa, with a prevalence of 0.5 to 2% among children and a mortality rate exceeding 50% in untreated cases. However, the lack of reliable data hampers effective public health policies and resource allocation. To address this, Mauritania’s Ministry of Health, with technical support from NGO Santé Sud, conducted its first prevalence survey in 2023-24. The findings will support advocacy for a national strategy on the disease and offer valuable insights for neighboring countries with similar challenges. Description of the problem The prevalence survey comprised 3 field missions over 7 weeks, conducted across 24 primary healthcare facilities during immunization days, in Nouakchott, Dakhlet-Nouadibou, Trarza, Ghorgol, Brakna, Guidimakha and Assaba regions: 1,642 infants (0-9 months) underwent screening for sickle cell disease, with parents’ consent, and 30 paramedics and laboratory technicians were trained to administer point-of-care tests. Results The survey found that 9.7% of tested children were carriers of hemoglobinopathies, with 0.6% diagnosed with sickle cell disease. Lab technicians and nurses have improved knowledge about the disease and are better equipped for point-of-care testing. This initiative is expected to enhance sickle cell disease control by providing crucial data for advocacy and may lead to a nationwide newborn screening program, in line with WHO recommendations. Lessons This initiative highlighted the efficiency of screening infants for sickle cell disease, emphasizing the need for effective organization involving stakeholders from central to local levels. Screening during immunization days proved highly efficient in testing numerous children. Success depends on adequate human resources, technical skills, and dedicated health personnel. Additionally, having a team member to inform and counsel families, especially when test results are positive, proved crucial. Key messages • A prevalence survey on sickle cell disease to generate robust data for advocacy efforts in Mauritania. • Conducting a prevalence survey on sickle cell disease in Mauritania for a better control of the disease.
