Endemic institutional strongyloidiasis in British Columbia.
The incidental finding in 1984 of Strongyloides stercoralis larvae in a resident of a chronic care institution who had a vague clinical illness prompted a review of the other residents. Five other cases were identified after exhaustive laboratory investigations. Fecal-oral spread was considered the most likely manner of the spread of infection. The possibility of endemic strongyloidiasis in institutions should be considered, even in temperate climates, when there is unexplained persistent illness or high eosinophil counts. Serologic testing is a useful adjunct to fecal examination in such situations.
