A carpenter deals with the Japanese lung fluke, which causes him to have trouble breathing, from eating live crabs. A bike rider develops a rash on her groin and upper thighs from a parasitic worm called Schistosoma, which could possibly give her bladder cancer. A guidance counselor, who was an army veteran, develops an insatiable appetite, unusual weight loss, and abdominal pain pulls out a parasitic roundworm called Ascaris lumbricoides, which he picked up from eating contaminated food while serving in the army.
