Abstract:
Rickettsia species are increasingly being recognized as a cause of infection among returning travelers. Murine typhus (MT) was mistakenly thought to have disappeared in the 1970s in Tunisia, yet recent serological data show that Rickettsia typhi, the causative agent of MT, still circulates in the Tunisian population. We report here a case of MT in a woman returning from Tunisia and hospitalized in France. Her presentation was nonspecific, with acute noneruptive fever. Diagnosis was confirmed by cross-adsorption and immunoblotting. Clinicians taking care of returning travelers with fever should be aware of MT, and know how to diagnose and treat it.
