Disease due to the tapeworm Taenia solium occurs in two forms: taeniasis and cysticercosis.
Taeniasis is the intestinal infection with adult tapeworms. It is a mild disease, but of significant public health importance as it plays a crucial role in the transmission of cysticercosis, a serious disease.
Cysticercosis is the infection with the larval stages (cysticerci) of the tapeworm. Inside the body, cysticerci can develop in a number of tissues; those that are located in the central nervous system cause neurocysticercosis, the most severe form of the disease.
Neurocysticercosis is considered to be a common infection of the central nervous system and is the most frequent preventable cause of epilepsy in the developing world.
