[Note: the free full text of this article is available as a PDF HERE. 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. In this case, one to three years after a major community outbreak, 5% of those who'd tested positive for giardiasis presented with long-lasting symptoms consistent with a diagnosis of ME/CFS. The authors note that this more than 8 times the normal ME/CFS rates of 0.23% to 0.56% in different populations.]

Background: A waterborne outbreak of Giardia lamblia gastroenteritis led to a high prevalance of long-lasting fatigue and abdominal symptoms. The aim was to describe the clinical characteristics, disability and employment loss in a case series of patients with Chronic Fatigue Syndrome (CFS) after the infection.

Methods: Patients who reported persistent fatigue, lowered functional capacity and sickness leave or delayed education after a large community outbreak of giardiasis enteritis in the city of Bergen, Norway were evaluated with the established Centers for Disease Control and Prevention criteria for CFS.

Fatigue was self-rated by the Fatigue Severity Scale (FSS). Physical and mental health status and functional impairment was measured by the Medical Outcome Severity Scale-short Form-36 (SF-36). The Hospital Anxiety and Depression Scale (HADS) was used to measure co-morbid anxiety and depression. Inability to work or study because of fatigue was determined by sickness absence certified by a doctor.

Results: A total of 58 (60%) out of 96 patients with long-lasting post-infectious fatigue after laboratory confirmed giardiasis were diagnosed with CFS.

In all, 1,262 patients had laboratory confirmed giardiasis. At the time of referral (mean illness duration 2.7 years) 16% reported improvement, 28% reported no change, and 57% reported progressive course with gradual worsening. Mean FSS score was 6.6. A distinctive pattern of impairment was documented with the SF-36. The physical functioning, vitality (energy/fatigue) and social functioning were especially reduced. Long-term sickness absence from studies and work was noted in all patients.

Conclusion:
After giardiasis enteritis at least 5% developed clinical characteristics and functional impairment comparable to previously described post-infectious fatigue syndrome.
