Onchocerciasis

Onchocerciasis, also known as river blindness, is an infectious parasitic disease that affects an estimated 18 million people worldwide, primarily in tropical and subtropical regions in Africa and Latin America. The disease is caused by Onchocerca volvulus, a filarial parasite, which is spread through bites from blackfly species found along fast flowing rivers. Symptoms of Onchocerciasis include intense itching, skin inflammation, skin lesions and ultimately, if left untreated, complete loss of vision due to an eye worm infestation. Onchocerciasis is a major health problem in many parts of the world, and has serious economic and social repercussions, such as causing reduced productivity and decrease in school attendance and educational performance. Treatment and control of Onchocerciasis involves various methods including the use of insecticide sprays, larviciding and the mass drug administration of drugs such as Ivermectin, which has been proven to be an effective treatment of the disease. By using prevention, early diagnosis and treatment efforts, as well as vector control measures, it is possible to reduce transmission of Onchocerciasis and improve the lives of millions of people. Through greater awareness and education, effective interventions and the elimination of Onchocerciasis are possible.
