esteem, it should go for the production of the medication in spite of the absence of benefit. According to the Centers for Disease Control and Prevention (CDC) “Onchocerciasis is a Neglected tropical disease caused by the parasitic worm Onchocerca volvulus. 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 and the infection can

caused by Onchocerca volvulus (O. volvulus), a parasitic worm carried by black flies of the Similium genus. Hundreds of thousands more are visually impaired as a result of the disease, and tens of millions are infected. Onchocerciasis, endemic in Africa and South America, causes an overpowering, painful itch, deterioration in vision, and, in some cases, total blindness. Clearly, onchocerciasis is an issue in dire need of a solution. Tetracycline, an obscure antibacterial,

Eliminating River Blindness in Ecuador You notice a figure sitting on a porch in the North-Western region of Ecuador. As you approach it appears to be an elderly man but as you approach him you notice that he has features that you have never seen before. His skin looks as if it has been draped onto his skeletal frame causing him to lose all age indicators. Your eyes reach his and he does not make eye contact, a clear indication that he is blind. You approach the lizard man and ask his age, he

Ethan Meyer Simulium Meridionale Species Report Biology Lab 104 September 19th, 2017 The Simulium Meridionale, more commonly known as the black fly or the turkey gnat, gets its energy by feeding on the blood of mammals. Their predators are slightly larger organisms like spiders, frogs, and trout (Defoliart 2004). They can be found wherever there is something they can feast on. Turkey gnats are notorious for being a nuisance from April to August due to their need to feed on blood. This is due

Several million cases of strep throat occur every year. Symptoms include a sore throat, fever, headache, fatigue, and nausea. Onchocerciasis- Onchocerciasis is caused by the larvae of Onchocerca volvulus, a parasitic worm that lives in the human body for years. It is endemic in Africa, where nearly all of the 18 million people infected with the disease live. Of those infected, over 6.5 million have developed dermatitis and around 270,000 have

The Centers for Disease Control and Prevention (CDC) define epidemic as “the occurrence of more cases of disease than expected in a given area or among a specific group of people over a particular period of time.” Epidemic of an infectious disease can be precipitated by a change in the host population, for example, an increase in the density of a vector species or an introduction of a new parasite due to an ecological disaster (flooding, famine, earthquake, etc). Epidemic can also be caused by human
