[Note: Giardiasis is an intestinal infection resulting from infestation with Giardia - a parasite commonly found worldwide and generally transmitted via human, animal or bird feces-contaminated water, food, or hands. Infection usually lasts a few weeks, but in some individuals may enter a prolonged phase.]
The aim of this study was to evaluate the prevalence of fatigue and abdominal symptoms 2 years after Giardia lamblia infection.
All 1262 cases who had Giardia-positive stool samples during an outbreak in 2004 in Norway received a questionnaire in 2006 asking about fatigue and abdominal symptoms.
• Fatigue was reported by 41%,
• Whereas 38% reported abdominal symptoms,
• And there was a highly significant association between these symptoms.
• Increasing age was a highly significant risk factor for fatigue.
• The symptoms were not due to chronic infection in this cohort.
Our data warrant further investigations into the late effects of giardiasis.
