    Introduction Schistosomiasis is second only to malaria in the number of people the disease disables or kills around the world(LAPA***). It is a tropical disease that is a major source of morbidity and mortality for developing countries in Africa, South America, the Caribbean, the Middle East, and Asia (LAPA***). In these endemic areas, there are no resources for access of fresh drinking water and adequate sanitation. Therefore, human feces are the main source for spreading of Schistosomiasis. The causative agent of Schistosomiasis is Schistosoma, which is caused by a parasitic worm or a eukaryotic fluke (Colley, 2014). The parasites that bring about schistosomiasis live in specific kinds of freshwater snails. The contagious type of the parasite is known as cercariae. These carcariae arise from the snail, which causes the fresh water to become contaminated. Infection can occur when skin comes into contact with the polluted water. Most human contaminations are brought about by Schistosoma mansoni, S. haematobium (urogenital), or S. japonicum (intestinal) (***). Each species is connected with specific types of snails, so the flukes ' transmission is characterized by…

    Combating schistosomiasis is a challenge as we can vaccinate against it or clean up water sources. Despite this though there have efforts to combat it, but if the data is anything to go by the battles have not been the most successful. A study done by Pimentel at al (2007:625), schistosomiasis is currently “infecting more than 200 million people, with death estimates of up to 200,000 per year” and that is continuing to grow. Many of the programs combating this disease are usually for ethical or…

    Describe (in your words) Schistosomiasis life cycle. Use the video in theme 1 as reference. Schistosomiasis is a parasite that penetrates the skin and enters the blood stream leaving behind its tail or known as cercariae form. The parasite then travels to the lungs for 4-6 weeks to mature. Once maturing for 4-6 weeks the parasite travels to the liver or sometimes heart to develop into adults male-female pairs. Once again, relocate to the preferred resting site, which varies based on species. …

    It is well known that praziquantel (PZQ) has contributed a lot and still contributing to control and prevent schistosomiasis and it is the only drug available for schistosomiasis. It has also the following important features: good efficacy, safety, operational convenience and low cost. However, exclusive use of it for controlling the disease has many limitations. For instance it does not prevent re-infection. Not only this but due to usage of the drug for more than three decades we may face…

    93). Water something that you would think is clean, safe, and able to drink without the fear of becoming sick. However, water is not that thing, and it will never be that. Schistosomiasis is a disease that is transmitted by freshwater snails. This snail then sends infected larva into slow-moving or still water, and then enters the body through the skin or body openings when people bathe or work in the water. Once they get inside the body, they grow and develop into mature worms, and they affect…

    Cloudy or bloody urine is not rare among communities extremely affected by schistosomiasis; rather, it becomes so mundane that it becomes part of the culture. For example, within the Bozo communities, young men have a rite of passage much like those of young women. Just as young women have a first menstrual bleed—or menarche—men are an equivalent: blood in their urine (Dettwyler 1994, 46). Obviously, this is a symptom of schistosomiasis rather than a natural bodily function. Nevertheless, both…
