Even on Airbnb, most guests will not cause as much drama as this patient’s unusual lodger.

The 49-year-old biologist presented to doctors in the Democratic Republic of the Congo after experiencing episodes of fever for several weeks.

When he did not improve, doctors swapped the norfloxacin for cefixime, but the symptoms persisted.
