Trematodiasis is an infection caused by flatworms known as trematodes, commonly referred to as flukes. These parasites can enter the human body through contaminated water or food, leading to various health issues. Symptoms may include abdominal pain, diarrhea, and fatigue, depending on the type of trematode involved. The most common types of trematodiasis are caused by Schistosoma species, which can lead to schistosomiasis, a serious condition affecting the liver and urinary system. Prevention focuses on avoiding contaminated water and practicing good hygiene. Treatment typically involves medications that target the parasites, helping to restore health and alleviate symptoms.
