Human trichinellosis in southern Spain: Serologic and epidemiologic study

An outbreak of trichinellosis caused by wild boar meat occurred in the Irue la (Jaen) in southern Spain in February 1996. Thirty-five people were diagn osed on the basis of epidemiologic data, but only 24 patients agreed to par ticipate in this study. Twenty-three (96%) had symptoms suggestive of trich inellosis. Immunofluorescent and Western blot test. results for trichinello sis were positive in 18 persons, and 15 had circulating Trichinella spirali s antigens. These findings suggest that results of tests for circulating an tigens in conjunction with clinical presentation are useful for the diagnos is of trichinellosis.
