Impact of Livestock Farming on Human Onchocerciasis in Adamawa and North Regions Cameroon

Background: Onchocerciasis or "river blindness" is currently a major cause of blindness in the world. The use of Ivermectin by the high risk population showed its limits. In these regions, cattle raising is the main occupation and human onchocerciasis is reduced since the high density of cattle stocking protects by zooprophylaxis and cross immunization. This work was carried out in order to know if cattle protect humans against human onchocerciasis. To achieve this goal, two high densities of cattle stocking and onchocerciasis zones were selected: Wakwa and Touboro, two zones of Cameroon located on the Vina River.
