Barmah Forest virus
Barmah Forest virus (BFV) is an illness transmitted by mosquitoes from animals to humans. In the Northern Territory (NT) it is the second most common mosquito transmitted virus after Ross River virus (RRV). It is characterised by painful or swollen joints lasting from days to months.
Seasonal risk
Mosquitos are an active part of the NT environment.
There is an increase risk of BFV between December and May, with February being a heightened risk due to favourable conditions for mosquitos that can spread BFV.
