- n. A disease caused by infestation with filarial worms of the genus Onchocerca, especially a disease of humans caused by O. volvulus and characterized by nodular swellings on the skin and lesions of the eyes. Transmitted by black flies, the disease occurs in tropical regions of Africa and Central America. Also called river blindness.

- n. An infection with nematodes of the genus Onchocerca, especially Onchocerca volvulus. Untreated, such infections can cause serious dermatological problems, and in advanced cases may lead to blindness. In certain areas of tropical Africa the blindness caused by onchocerciasis is called river blindness.

- n. infestation with slender threadlike roundworms (filaria) deposited under the skin by the bite of black fleas; when the eyes are involved it can result in blindness; common in Africa and tropical America
Hence the popular name for the disease that is more correctly called onchocerciasis, which can also produce a disfiguring skin inflammation and intense itching.
The disease, also called onchocerciasis, is caused by a parasitic worm, Onchocerca volvulus, whose larvae are transmitted in the bite of the black fly, which breeds by fast-flowing streams.
Also known as onchocerciasis, river blindness affects more than 17 million people worldwide, particularly in rural Africa.
The Director of Eye Health at South Sudan's health ministry, Ali Yousif Ngor, oversees the South Sudan part of an Africa-wide attempt to combat river blindness, also known as onchocerciasis (O. V).
Also called onchocerciasis, river blindness is caused by a parasitic worm whose larvae are transmitted by the bite of the black fly, which breeds by fast-flowing streams.
Two of the diseases, onchocerciasis, known as river blindness, and trachoma, a bacterial eye infection, cause blindness.
River blindness, or onchocerciasis, is spread by the bites of black flies, which carry the parasite from person to person.
"The onchocerciasis situation is more and more worrying in the zones extending south of the forest where 15 percent (of the population) has been affected," said Souleymane Yeo, who heads up the PLNCE programme.
Director of the African Programme for Onchocerciasis Control (APOC), Dr. Uche Amazigo, has revealed how the programme intends to use community-target approach to eliminate River Blindness (onchocerciasis) in endemic African countries.
APOC's strategy is based on preventive treatment of affected populations with a once-yearly dose of the anti-onchocerciasis drug ivermectin, according to Uche, who spoke with Hannah Brown, in an article published in Public Library Of Science (PLOS).
