Objective:
In this study, the clinical, laboratory and epidemiological features of rickettsial infection in Australian patients were examined.
Methods:
Patients with Rickettsia spp. seropositivity were selected from the database of the Australian Rickettsial Reference Laboratory. Questionnaires were sent to each referring physician with a request for information regarding the patient’s illness.
Results:
A retrospective analysis of 178 patients revealed the following common features in Australian rickettsial infection: fever, headache, myalgia, rash and a history of recent exposure to the Australian bush. The history included tick bites, eschar presence, respiratory abnormalities and acute fatigue, accompanied by abnormal haematology and liver function tests.
Conclusions:
A differential diagnosis including rickettsial infection should be confirmed (or refuted) by rickettsial serology.
