People contract the Murray Valley encephalitis virus by being bitten by an infected mosquito. The common banded mosquito, Culex annulirostris, is the usual culprit. You can find this mosquito (or it can find you) throughout Australia. It breeds in freshwater in spring, summer and autumn. It likes surface pools, rivers, natural wetlands and irrigation waters, but also enjoys backyards. It is especially common in the Murray-Darling river basin in summer.
