Onchocerciasis or river blindness is a parasitic disease with an insect vector that breeds in water. It is the world's second leading infectious cause of blindness. Controlling insect breeding sites in rivers is one of the pillars of prevention

What does ivermectin treat?
Ivermectin was introduced in the year the 1970s from a bacteria identified in a soil sample taken from a Japanese golf course's woodlands. In the years afterward, the efficiency of ivermectin and its derivatives in treating parasitic worm diseases has revolutionized human and veterinary medicine, earning William C Campbell and Satoshi Mura the Nobel Prize for their discovery. Ivermectin is now used in tablet form for the treatment of certain roundworm infections.
How does a Black swallowtail fly?
Do you really want to go into detail.....ha ha! Black flies, Simulium damnosum and S. neavei, transmit Onchocerca Volvulus, the causative agent of onchocerciasis in Africa. These insects lay their eggs in fast-flowing water such as streams and large rivers. S. Ochraceum, S.callidum, and S. metallicum transmit the disease in Mexico, Central and South America. These species lay their eggs in greater abundance in rapids and in areas below dams. Once the larvae hatch, the pupae stay in the aquatic habitat (Bogitsh & Cheng, 1998). Bogitsh, B. J., & Cheng, T.

What illnesses or diseases can people develop from the use of the Niger River?
River blindness (onchocerciasis) is the leading infectious disease that people can get or develop from the use of Niger River. It is caused by a worm (Onchocerca volvulus) that breeds in fast-flowing rivers. It is a major cause of blindness in west and central Africa. Symptoms of river blindness River blindness doesn't only cause blindness, it also creates nodules on the skin and severe itching. This results in damage to the pigment and over time the skin becomes mottled. This causes further problems because the de-pigmented spots are more susceptible to skin cancer. Impact of river blindness River blindness is endemic in certain areas. This has two important social implications: > children miss out on education because they are staying at home to act as full-time caregivers for older relatives who have become blind > people flee areas where the level of infection has hit hard, leaving 'ghost villages' behind. Unfortunately these infected areas are the ones with the most fertile land, closest to the river. Facts about river blindness > around 18 million people are infected, of whom roughly 300,000 are irreversibly blind > 99 per cent of those with river blindness live in Africa > a further 125 million people are currently at risk from infection
Blindness?
DefinitionBlindness is a lack of vision. It may also refer to a loss of vision that cannot be corrected with glasses or contact lenses.Partial blindness means you have very limited vision.Complete blindness means you cannot see anything and do not see light.People with vision worse than 20/200 are considered legally blind in most states in the United States.Alternative NamesLoss of visionCommon CausesBlindness has many causes. In the United States, the leading causes are diabetes, glaucoma, macular degeneration, and accidents (such as chemical burns or sports injuries).Worldwide, the leading causes of blindness are cataracts, onchocerciasis (river blindness), trachoma, leprosy, and vitamin A deficiency.Other causes include:Blocked blood vesselsComplications of premature birth (retrolental fibroplasia)Complications of eye surgeryLazy eyeOptic neuritisStrokeTay-Sachs diseaseRetinitis pigmentosaRetinoblastomaLead poisoningOptic gliomaHome CareIt is important for a blind person to be able to dress, eat, function independently, and stay safe. Many services are available that provide the training and support that allow blind people to function independently.Call your health care provider ifSudden vision loss is always an emergency, even if you have not completely lost all vision. You should never ignore loss of vision, thinking it will get better.Contact an ophthalmologist or go to the emergency room immediately. Most serious forms of vision loss are painless, and the absence of pain in no way diminishes the urgent need to get medical care. Many forms of vision loss only give you a short amount of time to be successfully treated.What to expect at your health care provider's officeA complete and thorough eye examination will be performed. The treatment plan will depend on the cause.
