Worm Infections River Blindness (Onchocerciasis) River blindness is a disease caused by Onchocerca volvulus, a parasitic worm transmitted to humans by the bite of infected black flies. Worm larvae that are transmitted develop into adult worms that settle in fibrous nodules on the human body. High risk destinations for infection? How is onchocerciasis transmitted? Onchocerciasis is caused by Onchocerca volvulus, a parasitic worm that lives for up to 14 years in the human body. It is spread through the bite of a black fly of the Simulium damnosum species complex, which breeds in fast-flowing rivers and streams. When the fly bites, it deposits the larvae of a parasitic worm, which matures to adulthood and produces millions of tiny worms, called microfilaria. Adults emerge after 8-12 days and live for up to four weeks, during which they can cover hundreds of kilometres in flight. What are the symptoms of onchocerciasis? When the microfilariae migrate throughout the body and give rise to a variety of symptoms rashes, lesions, intense itching and depigmentation of the skin; lymphadenitis, which results in hanging groins and elephantiasis of the genitals, general debilitation and serious visual impairment, including blindness. How is onchocerciasis treated? Stromectol (Ivermectin) the safe, effective drug capable of reducing the numbers of skin microfilariae in infected people and resulting in clinical improvement and decreased transmission of infection. Stromectol medication is used to treat certain parasitic roundworm infections. Contact Us By Phone : By Fax : +1 (646) 233 2033 +1 (646) 514-0273
