Rickettsia australis and Queensland Tick Typhus: A Rickettsial Spotted Fever Group Infection in Australia

Am J Trop Med Hyg. 2017 Jul;97(1):24-29. doi: 10.4269/ajtmh.16-0915.

Abstract

Rickettsia australis, the etiologic agent of Queensland tick typhus (QTT), is increasingly being recognized as a cause of community-acquired acute febrile illness in eastern Australia. Changing human population demographics, climate change, and increased understanding of expanding vector distribution indicate QTT is an emerging public health threat. This review summarizes the epidemiology, pathogenesis, clinical features, treatment principles, and future directions of this disease. Increased recognition of QTT will enable consideration of and prompt treatment of R. australis infection by clinicians in Australia.
