Ross River virus
Ross river virus (RRV) is an infection that is spread to humans through the bite of an infected mosquito.
Symptoms of infection include joint pain, fever and rash. Most people recover in a few weeks, but symptoms can continue for months.
The mosquitoes present in the Northern Territory (NT) that can spread the virus are Culex annulirostris (common banded mosquito), Aedes vigilax (salt marsh mosquito), Aedes normanensis (flood water mosquito) and Aedes notoscriptus (backyard mosquito).
Seasonal risk
Mosquitos are an active part of the Northern Territory (NT) environment.
There is an increase risk of RRV between December and March, with January being a heightened risk due to favourable conditions for mosquitos that can spread RRV.
