[Delayed diagnosis of Trichinelliasis focused in the Poznan Province].

The study compares chronologically the weeks in which Trichinella spiralis infected meat was consumed. The first symptoms appeared and clinical diagnosis of trichinellosis was made in 37 patients. Several factors were responsible for the delay in final diagnosis of trichinellosis: widely distributed infected meat, contemporary common respiratory viral infections in population with fever and myalgia, diagnostic difficulties in the first index case.
