What is trichinosis?
Trichinosis is a disease caused by parasitic roundworms (nematodes) that can infect and damage body tissues. Nematodes are a major division of the helminth family of parasitic worms (for example, Trichinella spiralis). When ingested, these parasitic nematodes can pass through the intestinal tract to invade other tissues, such as muscle, where they persist. Trichinosis is also termed trichinellosis, trichiniasis, or trichinelliasis. Trichinosis is not trichomoniasis, a sexually transmitted disease caused by the Trichomonas vaginalis parasite.
What are symptoms of trichinosis?
Trichinosis is usually characterized by two phases: the initial phase (intestinal) of abdominal discomfort, diarrhea, and nausea that begins one to two days after ingestion and the second phase (muscle) of muscle aches, itching, fever, chills, and joint pains that begins about two to eight weeks after ingestion. In addition, there can be "splinter" hemorrhages under fingernails and eye inflammation (conjunctivitis).
