Clinical findings:
(1) fever
(2) muscle pain or soreness
(3) gastrointestinal symptoms
(4) facial edema
(5) eosinophilia
(6) subconjunctival, subungual and retinal hemorrhages
Laboratory findings:
(1) Trichinella larvae demonstrated in muscle biopsy
(2) seroconversion of Trichinella-specific antibody (immunofluorescence, ELISA, Western blot)
Epidemiological findings:
(1) consumption of a meat contaminated with Trichinella larvae
(2) consumption of a potentially parasitized product from an animal with laboratory confirmed trichinellosis
(3) exposure to the same source of trichinellosis as a laboratory-confirmed human case
where:
• Demonstration of trichinella larvae in a muscle biopsy would seem pretty convincing evidence on its own.
• Eosinophilia is a laboratory test, but not a trichinella-related laboratory test.
