Niger Eliminates Onchocerciasis

February 3, 2025

Niger has made history as the first African nation to eliminate onchocerciasis, commonly known as river blindness. This milestone was recognised by the World Health Organisation (WHO), placing Niger alongside Colombia, Ecuador, Mexico, and Guatemala as countries free from this debilitating disease.

About Onchocerciasis

Onchocerciasis is caused by a parasitic worm and is transmitted through the bites of infected blackflies.
The disease primarily affects the skin and eyes, leading to severe skin conditions and potential blindness.
Historically, it has been public health issue, particularly in Africa, where over 99% of cases occur across 31 countries.

Niger’s Battle Against Onchocerciasis

Niger’s fight against onchocerciasis began over 50 years ago.
In the 1970s, approximately 500,000 people were infected or at risk. The prevalence of blindness was around 5%. In 1975, Niger joined the Onchocerciasis Control Programme (OCP) with ten other West African nations. By 2002, the prevalence had drastically reduced to just 0.02%.

Strategies for Elimination

Achieving elimination required extensive efforts beyond mere prevalence reduction. Key strategies included mapping high transmission areas, providing mass drug distributions, and training community health workers. Local communities were vital in these efforts, ensuring widespread participation and understanding of the disease’s impact.

The Role of Partnerships

Niger’s success was a collaborative effort involving governments, local communities, and international organisations.
This partnership provided financial support and technical expertise.
The engagement of frontline health workers was crucial in reaching remote areas and ensuring effective treatment delivery.

Social and Economic Impacts

Eliminating onchocerciasis has led to social and economic benefits. Patients no longer face out-of-pocket healthcare costs. Families can pursue education and job opportunities without the burden of caretaking for affected individuals. The economic return on investment has been substantial, with an estimated USD 2.8 billion added to Niger’s economy over 45 years.

The Path Forward

Niger’s experience serves as a model for other countries. To sustain these gains, governments must increase funding for neglected tropical disease (NTD) programmes and strengthen health systems. Technical and financial partners are encouraged to share resources and best practices. Empowering local communities is essential for achieving lasting change.

Global Efforts and Future Goals

Collaborative initiatives, such as the partnership with the CIFF and the Bill & Melinda Gates Foundation, aim to eliminate onchocerciasis and lymphatic filariasis in 39 countries. The goal is clear – replicate Niger’s model, invest in proven interventions, and maintain commitment to eradicate NTDs.
