Ross River Fever (RRF) is a mosquito-borne infectious disease caused by infection with the Ross River virus. The illness is typically characterized by an influenza-like illness and joint pain. The virus is endemic to Australia, Papua New Guinea, Fiji, Samoa, the Cook Islands, New Caledonia, and several other islands in the South Pacific.
The virus is spread only by mosquitoes, and is not contagious among humans. Vector insects acquire the virus from infected animals, such as kangaroos and wallabies, and pass it along to humans while feeding.
There are no specific treatments for RRF, nor are there any vaccines. Patients are usually treated for symptoms with analgesics and anti-inflammatories.
More than 30 species have been implicated as possible vectors, but the major species for Ross River Fever are:
- Aedes camptorhynchus in southern coastal regions
- Aedes vigilax in northern coastal regions
- Culex annulirostris in inland areas
