Onchocerciasis – or “river blindness” – is a parasitic disease caused by the filarial worm Onchocerca volvulus It is transmitted through the bites of infected blackflies (Simulium spp ) that breed in fast-flowing rivers and streams, mostly in remote villages located near fertile land where people rely on agriculture
- Onchocerciasis (river blindness)
Onchocerciasis – or “river blindness” – is a parasitic disease caused by the filarial worm Onchocerca volvulus transmitted by repeated bites of infected blackflies (Simulium spp ) These blackflies breed along fast-flowing rivers and streams, close to remote villages located near fertile land where people rely on agriculture
- Onchocerciasis (river blindness)
Onchocerciasis is caused by infection with a filarial nematode (Onchocerca volvulus) transmitted by infected blackflies (Simulium spp ) that breed in fast-flowing rivers and streams The adult worms produce embryonic larvae (microfilariae) that migrate to the skin, eyes and other organs Although most onchocerciasis occurs in sub-Saharan Africa, the infection also occurs in Yemen and two out
- 盘尾丝虫病 - World Health Organization (WHO)
重要事实 盘尾丝虫病又称河盲症，由寄生虫盘尾丝虫引起。 这种寄生虫会通过滋生于湍急河流中的受感染黑蝇的反复叮咬传播给人类。 症状包括严重瘙痒、皮肤损毁和视力损害，包括永久失明。 这种疾病主要影响撒哈拉以南非洲和也门的农村人口，拉丁美洲部分地区也有发现较小的流行区疫源地
- Control of Neglected Tropical Diseases
Onchocerciasis Control Programme (OCP) Between 1974 and 2002, onchocerciasis was brought under control in West Africa through the work of the Onchocerciasis Control Programme (OCP), using mainly the spray of insecticides against black-fly larvae (vector control) by helicopters and airplanes
- Onchocerciasis: diagnostic target product profile to support preventive . . .
Onchocerciasis, also known as river blindness, affects an estimated 21 million people, with 99% of cases reported in 31 sub-Saharan countries (WHO, 2020a) The disease is caused by the filarial worm Onchocerca volvulus, which is transmitted by Simulium flies Adult worms live in nodules, some of which are subcutaneous Conversely, the embryos (microfilariae) can migrate through the skin
- Elimination of human onchocerciasis: progress report, 2023–2024
Overview Onchocerciasis, more commonly known as river blindness, is a neglected tropical disease caused by the parasitic worm Onchocerca volvulus The disease is transmitted to humans through the bite of an infected blackfly (Simulium spp ), which breeds in fast-flowing rivers and streams The blackfly vector ingests microfilariae (immature worms) when it bites an infected person Inside the
- Verifying the elimination of onchocerciasis - World Health Organization . . .
Certification of onchocerciasis elimination is the official recognition by WHO of a country’s onchocerciasis-free status WHO has developed a framework for the control, elimination and eradication of NTDs that outlines a standardized process for reviewing and confirming the achievement of the NTD road map targets
