The Ross River Virus (RRV) is an arbovirus of the family Togaviridae , genus alphavirus . It is in Australia to Papua New Guinea and the neighboring islands endemic and annually conducts several thousand diseases (so-called. Ross River fever or epidemic polyarthritis ).
history
The disease has been known since the 1930s, and the virus was first isolated in the 1960s. Since then, the virus has spread further, presumably because new and therefore non-immune population groups were affected by increased migration . Endemic areas are found in South Australia, the Northern Territory, Queensland, Victoria and New South Wales. A further spread is theoretically possible, since the vectors ( mosquitoes ) that spread the virus also occur on other continents .
Route of infection
It is transmitted by mosquitoes of the genera Aedes , Culex and Mansonia . The virus reservoir is probably small mammals.
clinic

The disease is self-limiting, but symptoms can last for months to years.
therapy
There is no vaccination or specific therapy, the therapy is symptomatic . Protection from mosquitoes is advisable in the affected areas.
