BLINDING, DISFIGURING, and long considered an inescapable burden for millions, river blindness has plagued communities in Niger for generations.
Now, the country has made history as the first in Africa to eliminate the disease, a milestone officially confirmed by the World Health Organization (WHO).
Niger’s achievement places it among only five countries worldwide to have successfully interrupted transmission of the Onchocerca volvulus parasite.
River blindness, or onchocerciasis, is a parasitic infection spread through the bites of black flies, primarily affecting rural populations in sub-Saharan Africa.
The disease causes severe itching, skin disfigurement, and irreversible blindness, leading to economic hardship as people abandon fertile riverbanks to escape infection.
Once widespread in Niger, transmission has now been halted, marking a major victory for public health in the region.
Decades of targeted interventions led to this success. From 1976 to 1989, Niger implemented vector control strategies under the WHO Onchocerciasis Control Programme in West Africa, using insecticide spraying to curb the black fly population.
Later, mass drug administration (MDA) campaigns introduced ivermectin, donated by Merck Sharpe & Dohme (MSD), significantly reducing the disease’s prevalence.
Between 2008 and 2019, the country intensified MDA efforts, combining ivermectin with albendazole to tackle both onchocerciasis and lymphatic filariasis (LF).
By 2014, after stopping LF treatment in most areas, Niger launched extensive epidemiological and entomological surveys to assess onchocerciasis transmission.
The findings were groundbreaking—prevalence dropped from approximately 60% to just 0.02%.
The sustained combination of medicine and vector control had successfully broken the cycle of infection.
Collaboration played a crucial role.
The Nigerien government worked alongside WHO, non-governmental organisations, and international partners to mobilise resources and technical expertise.
Continuous disease monitoring ensured effective strategies, enabling Niger to meet WHO’s strict verification criteria for elimination.
“Onchocerciasis has long caused immense suffering and economic hardship,” said Dr Matshidiso Moeti, WHO Regional Director for Africa.
“Niger’s achievement ends this burden for its people and sets an example for other African nations fighting neglected tropical diseases. This success reaffirms that elimination is possible.”
According to WHO, Niger now joins Colombia, Ecuador, Guatemala, and Mexico as the only countries worldwide to have eliminated river blindness.
In Africa, 21 nations have eradicated at least one neglected tropical disease, with Niger having already eliminated Guinea-worm disease in 2013, the WHO affirms.
With this historic victory, the agency notes that Niger’s success fuels hope for other endemic regions, proving that determination, strategic partnerships, and sustained medical interventions can overcome even the most persistent public health challenges.
