B65-B83: Helminthiases

B70: Diphyllobothriasis and sparganosis

Diphyllobothriasis and sparganosis are medical conditions that result from infections with certain types of parasites. Diphyllobothriasis is caused by ingesting tapeworm larvae, usually through undercooked or raw freshwater fish. Symptoms may include abdominal pain, diarrhea, and weight loss. Sparganosis occurs when tapeworm larvae infect different parts of the body, often through contaminated water or undercooked frog or snake meat. Symptoms and progression depend on where in the body the larvae are; they may cause lumps under the skin, eye or brain issues, or other problems. Both conditions can affect anyone, but are more common in areas where consuming these types of foods is customary. As the parasites mature, they can lead to more severe issues like nutrient deficiencies, so early detection is crucial.
