Tapeworms
Tapeworms are flatworms that live in the digestive tract. Each tapeworm’s body is long and made up of segments which grow and extend as it gets more nutrients from the body. Humans can get infected by this parasite if they consume contaminated food or water. One kind of tapeworm infection is also known as cysticercosis, wherein the larvae of the tapeworm enters the bloodstream and can travel to different parts of the body like the muscles and brain, forming cysts. Depending on where the cysts are located, they can cause seizures, problems with vision, and body weakness.
