Reducing river blindness and lymphatic filariasis

River blindness and lymphatic filariasis are debilitating diseases caused by parasite infections. Our programme aims to eliminate them by giving medication to those at risk.

Neglected tropical diseases (NTDs) affect more than a billion of the world’s poorest people. Sightsavers, with additional funding from the UK government, is helping to eliminate two significant NTDs that cause both pain and disability.

River blindness and lymphatic filariasis are debilitating diseases caused by parasite infections. River blindness is transmitted via the bite of infected black flies. Infection leads to severe skin disease with unrelenting itching, visual impairment and blindness.

Lymphatic filariasis is transmitted via mosquito bite and affects up to 120 million people. Long-term infection causes painful disability, which can profoundly affect the lives of individuals, reducing their independence, productivity and mobility. The disfigurement and associated stigma and discrimination can have a devastating impact on the affected, their families and their communities.

How does the programme help?

While river blindness is transmitted by the black fly and lymphatic filariasis is transmitted by the mosquito, both diseases are caused by an infection of the filarial worm that can be treated with the same medication – Mectizan®. The World Health Organization recommends coordinating treatment for river blindness and lymphatic filariasis because the two diseases often appear together in communities.

By adding albendazole, a common de-worming medication, in areas where lymphatic filariasis is present, both diseases can be successfully treated together efficiently and cost-effectively.

The three-year river blindness and lymphatic filariasis programme supports country-led plans to deliver treatment to stop the transmission of infection and also stop the flies that transmit river blindness from breeding. The programme  also helps to manage the pain associated with lymphatic filariasis through patient care and treatment.

Where does it operate?

Sub-Saharan Africa carries almost the entire global burden of both of these NTDs. The programme runs across four countries: Democratic Republic of Congo, Guinea Bissau, Nigeria and Uganda.

One of the unfortunate outcomes of these NTDs is that people are forced to move away from fertile river valleys, where the diseases are prevalent, which means they struggle to find suitable areas to grow crops or farm, pushing families and communities into poverty.

Poverty is both a cause and consequence of the poor health caused by these diseases. This project targets men, women and children in these hard-to-reach communities. By contributing to the elimination of these debilitating diseases, Sightsavers, with help from the UK government, aims to develop healthy communities  where children no longer struggle with the health risks faced by their parents and grandparents.
