Neurocyticercosis was commonly thought to be transmitted only through eating raw pork infected with the cysts of T. solium. However, in 1992, a U.S. outbreak of the disease occurred in a sect of Orthodox Jews who abstain from eating pork. Subsequent epid
emiological studies indicated that the Latin American immigrant housekeepers of those infected had transmitted the disease to their employers via the fecal-oral route.
Studies based on autopsy results indicate that approximately one percent of the population of Mexico City has neurocysticercosis.
