Murine typhus: forgotten but not gone.

An occasional patient presents the classical symptoms of a disease that has become uncommon. Typhus is an example of such a disease, since it is now well contained through control of its rodent reservoir. It is readily treated with tetracycline or one of its long-acting analogues, doxycycline or minocycline. Because typhus is infrequently encountered, the physician may not initially include it in his differential diagnosis. Our case serves as a remainder that with the increasingly frequent movement of persons from one geographic area to another, the uncommon rickettsial infection, murine typhus, should continue to be in the differential of a febrile patient. Furthermore, our case underscores the importance of including typhus in the differential of typhoid fever.
