Symptoms are caused by the microfilariae, which move around the human body in the subcutaneous tissue and induce intense inflammatory responses when they die. Infected people may show symptoms such as severe itching and various skin changes. Some infected people develop eye lesions which can lead to visual impairment and permanent blindness. In most cases, nodules under the skin form around the adult worms.]]> 2021-11-29 05:21:01 UTC https://padlet.com/budfrayer/4wr3o5at3q89n32u/wish/1917140661 budfrayer https://padlet.com/budfrayer/4wr3o5at3q89n32u/wish/1917141094 2021-11-29 05:21:25 UTC https://padlet.com/budfrayer/4wr3o5at3q89n32u/wish/1917141094 budfrayer https://padlet.com/budfrayer/4wr3o5at3q89n32u/wish/1917157535 There is no vaccine or medication to prevent infection with O. volvulus.
Between 1974 and 2002, disease caused by onchocerciasis was brought under control in West Africa through the work of the Onchocerciasis Control Programme (OCP), using mainly the spraying of insecticides against blackfly larvae (vector control) by helicopters and airplanes. This has been supplemented by large-scale distribution of ivermectin since 1989.The OCP relieved 40 million people from infection, prevented blindness in 600 000 people, and ensured that 18 million children were born free from the threat of the disease and blindness. In addition, 25 million hectares of abandoned arable land were reclaimed for settlement and agricultural production, capable of feeding 17 million people annually.
The African Programme for Onchocerciasis Control (APOC) was launched in 1995 with the objective of controlling onchocerciasis in the remaining endemic countries in Africa and closed at the end of 2015 after beginning the transition to onchocerciasis elimination. Its main strategy has been the establishment of sustainable community-directed treatment with ivermectin (CDTI) and vector control with environmentally-safe methods where appropriate]]> 2021-11-29 05:38:06 UTC https://padlet.com/budfrayer/4wr3o5at3q89n32u/wish/1917157535 budfrayer https://padlet.com/budfrayer/4wr3o5at3q89n32u/wish/1917160099 It is transmitted through repeated bites by blackflies of the genus Simulium.   The people most at risk for acquiring onchocerciasis are those who live or work near streams or rivers where there are Simulium blackflies.

It is transmitted through repeated bites by blackflies of the genus Simulium. The disease is called river blindness because the blackfly that transmits the infection lives and breeds near fast-flowing streams and rivers, mostly near remote rural villages. The infection can result in visual impairment and sometimes blindness. Additionally, onchocerciasis can cause skin disease, including intense itching, rashes, or nodules under the skin. Worldwide onchocerciasis is second only to trachoma as an infectious cause of blindness.]]> 2021-11-29 05:45:04 UTC https://padlet.com/budfrayer/4wr3o5at3q89n32u/wish/1917164740 budfrayer https://padlet.com/budfrayer/4wr3o5at3q89n32u/wish/1917167577 2021-11-29 05:47:54 UTC https://padlet.com/budfrayer/4wr3o5at3q89n32u/wish/1917167577 budfrayer https://padlet.com/budfrayer/4wr3o5at3q89n32u/wish/1917169151  The agent of river blindness, Onchocerca volvulus, occurs mainly in Africa, with additional foci in Latin America and the Middle East. ]]> 2021-11-29 05:49:28 UTC https://padlet.com/budfrayer/4wr3o5at3q89n32u/wish/1917169151 budfrayer https://padlet.com/budfrayer/4wr3o5at3q89n32u/wish/1917171868 2021-11-29 05:52:16 UTC https://padlet.com/budfrayer/4wr3o5at3q89n32u/wish/1917171868 budfrayer https://padlet.com/budfrayer/4wr3o5at3q89n32u/wish/1917172217 2021-11-29 05:52:37 UTC https://padlet.com/budfrayer/4wr3o5at3q89n32u/wish/1917172217 budfrayer https://padlet.com/budfrayer/4wr3o5at3q89n32u/wish/1917172578 2021-11-29 05:53:02 UTC https://padlet.com/budfrayer/4wr3o5at3q89n32u/wish/1917172578 budfrayer https://padlet.com/budfrayer/4wr3o5at3q89n32u/wish/1917173112 2021-11-29 05:53:36 UTC https://padlet.com/budfrayer/4wr3o5at3q89n32u/wish/1917173112
