The questionnaire covered per-sonal and demographic data, behavioral risk factors, and possible chronic complaints related to yersiniosis.Among the 433 responders, 51 (11.8%) were seropositive for IgG or IgA in the 1987 survey, 380 were seronegative, and 2 had ambiguous results.No difference was observed between the seropositive and seronegativegroups regarding education, annual income, general behavioral risk factors like smoking, alcohol consumption, physical activity, and dietary parameters;or diagnosed chronic illness. However, the seropositives weresignificantly more likely than the seronegatives to report recurrent diarrhea, painful or swollen joints, and muscle pain. Also, presence of all three complaints was more common among seropositives. Conclusion: The present study shows that uncomplicated Y.enterocolitica O:3 infection is a risk factor regarding future development of chronic complaintssuch as diarrhea, and joint and muscle complaint.展开更多
