Tapeworm
Tapeworm, also known as cestode, is a type of parasitic worm that can cause a variety of illnesses in humans. Tapeworms feed on the nutrients in the intestines of their human host, and can grow to several feet in length. Tapeworms are most commonly transmitted through the ingestion of fecal matter, typically from undercooked meat or fish. Symptoms of tapeworm infection may include abdominal pain, nausea, and diarrhea, as well as fatigue and weight loss. Tapeworms can also spread to other parts of the body, including the brain, heart, and lungs. Treatment typically involves the use of oral medications, such as praziquantel, to kill the worms and their eggs. In severe cases, surgery may be needed to remove the worms.
