MCQ Quiz On Schistosomiasis

Explanation
Schistosomiasis is commonly known as Bilharzia. It is a parasitic disease caused by Schistosoma parasites. The parasites are transmitted to humans through contact with contaminated water. The symptoms of Schistosomiasis include fever, abdominal pain, diarrhea, and blood in the urine. If left untreated, it can lead to chronic health problems such as liver damage, kidney failure, and bladder cancer. Therefore, Bilharzia is the correct alternative name for Schistosomiasis.

Explanation
The correct answer is 5 because there are five known species of the schistosoma parasite.

Explanation
Schistosomiasis is a water-borne disease because it is caused by parasitic worms that are transmitted to humans through contact with contaminated water. The parasites, known as schistosomes, are released into freshwater bodies by infected snails. When individuals come into contact with the contaminated water, the parasites can penetrate their skin and enter the bloodstream, causing schistosomiasis. This disease is commonly found in areas with inadequate sanitation and access to clean water sources.

Explanation
The correct answer is All of these places. The parasite can be found in the Middle East, Southeast Asia, and the Caribbean. This suggests that the parasite has a wide geographical distribution and is not limited to a specific region.

Explanation
In 1949, Bilharzia saved Taiwan from Chinese invasion. This suggests that Bilharzia played a significant role in preventing the Chinese invasion of Taiwan during that year. However, without further information, it is unclear how exactly Bilharzia contributed to this outcome.

Explanation
Schistosomiasis is a parasitic disease caused by worms called schistosomes. These worms are not found in the United States. However, they can be found in countries like India, Brazil, and France.

Explanation
Schistosomiasis is a parasitic disease caused by flatworms called Schistosomes. The life cycle of schistosomiasis involves two hosts - a definitive host (usually humans) and an intermediate host. The correct answer is "snails" because snails act as the intermediate host for Schistosomes. The parasite's eggs are released into freshwater where they hatch and infect snails. Inside the snail, the parasite undergoes several developmental stages before being released back into the water, where it can infect humans or other definitive hosts. Thus, snails play a crucial role in the transmission and life cycle of schistosomiasis.

Explanation
Schistosoma mansoni is a parasitic worm that causes schistosomiasis in humans. The mode of transmission for this parasite is through direct contact with contaminated freshwater. The larvae of the parasite penetrate the skin of individuals who come into contact with the contaminated water. Once inside the body, the larvae migrate to the liver and intestines, where they mature and reproduce. Therefore, the correct answer is "skin" as it is the site of penetration for Schistosoma mansoni.

Explanation
Children who are repeatedly infected with this disease can develop anemia, learning difficulties, and malnutrition. Repeated infections can lead to a decrease in red blood cells, causing anemia. Additionally, the disease can affect the child's cognitive abilities, resulting in learning difficulties. Moreover, the constant illness can interfere with the child's appetite and nutrient absorption, leading to malnutrition. Therefore, all of the mentioned conditions can occur in children repeatedly infected with this disease.

Explanation
Insect repellent is designed to keep insects away, and it can be effective in preventing insect bites. Bilharzia, also known as schistosomiasis, is a parasitic infection that is transmitted by freshwater snails. It is not directly related to insects. Therefore, it is reasonable to agree with the statement that insect repellent can protect against Bilharzia, as it can help reduce the risk of insect bites that may indirectly lead to the transmission of the disease.
