Acute polyarthritis revealing hepatitis E.

We report a case of acute hepatitis E occurring in a 51-year-old French woman, revealed by an abrupt onset of polyarthritis involving the ankles and knees followed by the wrists and fingers. Polyarthritis lasted up to 3 months without recurrence. Our case was characterised by a 9-month prolonged viraemia with persistence of specific IgM in the serum.
