- Can ivermectin mass treatments eliminate onchocerciasis in Africa? Winnen, M.; Plaisier, A.P.; Alley, E.S.; Nagelkerke, N.J.D.; van Oortmarssen, G.; Boatin, B.A.; Habbema, J.D.F. // Bulletin of the World Health Organization;2002, Vol. 80 Issue 5, p384
Objective To elucidate the conditions in which mass treatment with ivermectin reduces the transmission of Onchocerca volvulus sufficiently to eliminate infection from an African community. Methods ONCHOSIM, a microsimulation model for onchocerciasis transmission, was used to explore the...

- River Blindness. Desowitz, Robert S. // Natural History;Aug-Sep79, Vol. 88 Issue 7, p48
Focuses on river blindness, ocular lesions caused by the parasitic filarial worm Onchocerca volvulus and its vector, the blackfly Simulium damnosum. Lack of knowledge in their underlying pathogenesis; Drawbacks of methods for controlling the disease; Therapeutic use of diethylcarbamazine.
- Eye disease beaten. Heaven, Douglas // New Scientist;8/10/2013, Vol. 219 Issue 2929, p6
The article reports that Colombia has become the first country to eradicate river blindness, a disease caused by a parasitic filarial worm, Onchocerca volvulus, that affects people living in 30 countries in Africa and South America.
- Onchocerciasis (river blindness). // Weekly Epidemiological Record;10/10/2003, Vol. 78 Issue 41, p361
Cites several information sources on onchocerciasis, or river blindness, in reference to a report from the 12th InterAmerican Conference on Onchocerciasis in Manaus, Brazil. Description of the filarial parasite Onchocerca volvulus as the caused of onchocerciasis; Estimated number of persons who...
- The Current Biomedical Trends of Onchocerciasis, an Age Old Disease of Man. Orji, A.; Nwachukwu, N. C.; Madu, B. O. // European Journal of Scientific Research;Feb2008, Vol. 19 Issue 3, p462
Onchocerciasis is an insidious non-fatal filarial disease that has caused blindness, life long human suffering and grave socioeconomic problems. The disease is commonly known as River blindness because the vector of the parasite usually breed in fast flowing rivers. It is the world second...
- Rapid Epidemiological Assessment of Onchocerciasis in a Tropical Semi-Urban Community, Enugu State, Nigeria. Eyo, J. E.; Onyishi, G. C.; Ugokwe, C. U. // Iranian Journal of Parasitology;2013, Vol. 8 Issue 1, p145
Background: This study was carried out in Opi-Agu a tropical semi-urban autonomous community comprising of three villages in Enugu State, Nigeria, between the months of April and June 2010. It was designed to determine the prevalence of Onchocerca volvulus infection and assess the perception of...
- Density-Dependent Mortality of the Human Host in Onchocerciasis: Relationships between Microfilarial Load and Excess Mortality. Walker, Martin; Little, Mark P.; Wagner, Karen S.; Soumbey-Alley, Edoh W.; Boatin, Boakye A.; Basáñez, María-Gloria // PLoS Neglected Tropical Diseases;Mar2012, Vol. 6 Issue 3, p1
Background: The parasite Onchocerca volvulus has, until recently, been regarded as the cause of a chronic yet non-fatal condition. Recent analyses, however, have indicated that in addition to blindness, the parasite can also be directly associated with human mortality. Such analyses also...
- Uncertainty Surrounding Projections of the Long-Term Impact of Ivermectin Treatment on Human Onchocerciasis. Turner, Hugo C.; Churcher, Thomas S.; Walker, Martin; Osei-Atweneboana, Mike Y.; Prichard, Roger K.; Basáñez, María-Gloria // PLoS Neglected Tropical Diseases;Apr2013, Vol. 7 Issue 4, p1
Background: Recent studies in Mali, Nigeria, and Senegal have indicated that annual (or biannual) ivermectin distribution may lead to local elimination of human onchocerciasis in certain African foci. Modelling-based projections have been used to estimate the required duration of ivermectin...
