In a groundbreaking achievement, Niger has become the first African country to eliminate onchocerciasis, also known as river blindness. This parasitic disease is the second leading infectious cause of blindness worldwide and primarily affects rural populations in sub-Saharan Africa and Yemen.
The World Health Organization (WHO) has congratulated Niger for meeting the criteria for onchocerciasis elimination, making it the fifth country globally to achieve this feat. “Eliminating a disease is a significant achievement that requires tireless dedication,” said Dr. Tedros Adhanom Ghebreyesus, WHO Director-General.
Niger’s success is attributed to effective country-led efforts and partnerships. Between 1976 and 1989, the country undertook vector control measures, spraying insecticides to decrease transmission. Later, mass drug administration with ivermectin and albendazole was implemented, followed by surveillance.
The combination of medicine and vector control led to a significant reduction in prevalence, from approximately 60% to 0.02%. Continuous monitoring and timely adjustments in strategies ensured the effectiveness of interventions.
Niger’s achievement positions the country as a model for eliminating neglected tropical diseases in Africa. The country had previously eliminated Guinea-worm disease in 2013. Globally, 54 countries have eliminated at least one neglected tropical disease, with Niger joining four other countries verified by WHO for eliminating onchocerciasis.
