[Trichinosis in Provence. Apropos of a familial epidemic].

An outbreak of trichinosis following meals in a rural area of Provence is reported. The epidemiologic parameters reconstitute the contamination cycle (man-pig: fox-rat) which indicated indisputably the diagnosis, the appropriate therapy, and also evidenced a rural zoonosis of trichinosis in Provence. The clinical picture among twenty-one people included morbilliform rash in 38% of cases and an enanthema in 24% of cases, uncommon findings, with respect to their frequency, and the other usual signs. Early laboratory diagnosis was made possible by blood analysis for hypereosinophilia and immunoassay (ELISA) for antigen-specific IgE. Treatment with benzimidazoles was quite effective.
