Short answer

Queensland tick typhus is an Australian spotted fever rickettsiosis associated with tick exposure and may cause fever, headache, rash and an eschar at the bite site.

At a glance

Regional exposure and clinical assessment are essential because symptoms overlap with other infections and not every feature is present.

Key takeaways

• Report Australian travel and bush exposure.

• Photograph any eschar or rash.

• Seek prompt medical advice for fever.

A locally recognised rickettsial illness

Rickettsia australis is the recognised cause. Exposure can occur in eastern Australian tick habitat, and a remembered tick bite is not required.

Clinical advice is time-sensitive

Do not attempt to distinguish rickettsial diseases from appearance alone. A clinician assesses symptoms, location and tests and decides treatment.
