Abstract

Introduction Neurocysticercosis (NCC) is parasitic central nervous system infection by Taenia solium larval cysts. The epidemiology in Oregon is poorly understood and the public health role is unclear. Objectives We conducted population surveillance in Oregon to determine the incidence of NCC, and to pilot targeted screening for tapeworms among affected households. Methods We examined hospital billing codes and medical charts for NCC diagnosed between January 1, 2006 and December 31, 2009. We collected stool and blood from household members in a subset of recent cases to screen for T. solium tapeworms and cysticercosis. Results We identified 87 incident cases for an annual incidence of 5.8/100,000 population among Hispanics. In 22 household investigations we found 2 additional NCC cases, but no evidence of current tapeworm infection. Conclusion Taenia solium infection is an important clinical and public health disease in Oregon, particularly among Hispanics. Public health intervention should focus on family members of identified cases, as household investigations can identify additional T. solium infection.
