ABSTRACT
This progress report provides an update on the progress made towards eliminating nnchocerciasis (river blindness) by the World Health Organization (WHO) as part of its road map on neglected tropical diseases for 2021-2030. The report highlights that the goal is to eliminate the need for mass drug administration of ivermectin in at least one focus in 34 countries by 2030, in more than 50% of the population in at least 16 countries and in the entire endemic population in at least 12 countries. However, challenges remain in achieving these goals, including incomplete mapping of all transmission zones, co-endemicity of onchocerciasis and loiasis, a potential decrease in sensitivity to ivermectin, uncoordinated cross-border work, suboptimal programme implementation and inadequate technical and financial resources. COVID-19 has also delayed national programmes, with millions of doses of preventive chemotherapy that should have been distributed expiring. The report also provides regional highlights, including that in 2021, 23 countries reported having treated a total of 142.3 million people for onchocerciasis, representing 58.1% of global coverage, and that the African region faces the greatest challenge with 99% of the global burden of the disease in this region.
