Yersinia enterocolitica: A Follow-up of the Outbreak in the Norwegian Armed Forces in 2014.

One strength of this study is that we were able to investigate a large outbreak of YE gastroenteritis in a group of individuals with good underlying health. Weaknesses are the low response rate, especially in the control group, and the fact that we sent out the questionnaire >4 years after the acute gastroenteritis occurred. YE gastroenteritis among personnel in the Norwegian Armed Forces was associated with a significantly longer duration of illness and a longer duration of absence from service than that resulting from an unspecified acute infectious gastroenteritis. However, YE gastroenteritis was not associated with more symptoms of post-infectious complications.
