“…CASE PRESENTATION: We present a young pregnant female who developed bilateral sensorineural deafness on the fifth day of an acute febrile illness with a maculopapular rash. Rickettsia conorii IgG (>1/450) became highly positive, and she received oral azithromycin for ten days with complete resolution of fever and rash. …”
