We don't mind informing someone that we have a bacterial or viral infection, like strep throat or influenza. Most of us, though, would hesitate before confessing we had tapeworms. Parasitic infections feel more intrusive—somehow more of a violation than other forms of infection. Surprisingly, though, a very large percentage of the world's populatio...
Neurocysticercosis occurs via fecal-oral transmission, or when people are exposed to human feces containing the eggs of Taenia solium, a pork tapeworm. Handwashing and kitchen cleanliness are critical so as not to ingest the eggs. Ingesting the eggs leads to tapeworm larvae growing in many different human tissues, particularly brain and muscle. Thi...
Toxoplasmosis is a parasite infection caused by the protozoan Toxoplasma gondii. It is widely spread throughout the world, with about 15% of people in the U.S. and about 50% of people in Europe have a positive antibody test for the disease. Sometimes, a toxoplasma infection can seed the brain and spinal cord, and cysts can live there for years. How...
Without exaggeration, malaria is one of the most serious threats to human life throughout the entire history of humankind. Over millennia, the disease has killed hundreds of millions of people. The workings of this parasite are complex, but almost always involve being transmitted by an infected mosquito. Here we will only briefly discuss one of mal...
Trypanosomiasis, also called sleeping sickness, is caused by the protozoan parasites Trypanosoma brucei gambiense or Trypanosoma brucei rhodesiense. Like malaria, the parasite is spread by an insect host. American trypanosomiasis is transmitted by the assassinbug. African trypanosomiasis is spread by the tsetse fly, which leaves a painful, two to f...
Schistosomiasis, also called bilharzia or bilharziasis, is caused by infection with small, flatworms called flukes. Usually, these small, leaf-shaped worms cause intestinal, liver, kidney, or bladder problems. Globally in 2017, almost 99 million people were treated for schistosomiasis, which is often acquired through bathing and swimming in freshwa...
Echinococcus, also called hydatidosis, is a tapeworm which, in the early stage of life, can cause cysts in living human tissue including the brain and spinal cord. The parasites which are responsible include Echinococcus granulosus and Echinococcus multilocularis. Humans acquire the infection by eating contaminated food. The disease is rare in the ...
Trichinellosis is an infection caused by roundworms (nematodes) and is most commonly found in undercooked pig meat (though it can be found in other types of meat as well.) The infection is relatively uncommon in the United States due to improvements in food preparation. Larvae invade the wall of the small bowel and develop into adult worms. Worms t...
Paragonimiasis is a parasitic infection with a flatworm which may enter the body through eating undercooked crab or crayfish. It is rare in the United States, though several cases have been reported in the Midwest. Most commonly it is found in East Asian countries. The parasite does not often affect the central nervous system but the parasite may r...
Angiostrongyliasis is a parasitic infection caused by Angiostrongylus cantonensis,which is most common in Southeast Asia but may occur in the Caribbean as well. It is contracted from eating undercooked snails, slugs, crabs, or prawns. The larva of this parasite migrates to the brain causing headaches, nausea, and neck stiffness. In contrast to many...

In some parts of the world, brain infections may be due to worms or other parasites. These infections are more common in low-resource countries and rural areas. They are less common in the United States. (See also Overview of Brain Infections.) Neurocysticercosis is caused by pork tapeworm larvae.
