Japanese encephalitis virus (JEV) was detected in Victoria for the first time in February 2022.
This mosquito season human cases of JEV infection have been reported in Victoria, New South Wales and South Australia.
JEV is a rare but potentially serious infection of the brain caused by a virus spread through mosquito bites. If you have JEV, you most likely won't have symptoms. But if you have been in contact with mosquitoes and develop a sudden high fever and headache in the following days and weeks, see your doctor. If you have more serious symptoms like disorientation or a seizure - urgently seek medical attention.
Children under 5 and older people have a higher risk of developing more severe illness, like encephalitis.
Take precautions to avoid mosquito bites around your home and yard, when you’re on holidays and spending time outdoors.
Heavy rainfall over the winter months creates ideal breeding conditions for mosquitoes that can spread disease. High numbers of mosquitoes will continue over the summer months across rural Victoria.
Mosquitoes can carry diseases such as Ross River virus, Barmah Forest virus, Japanese Encephalitis virus and Murray Valley Encephalitis (MVE) – all serious, infectious and potentially life-threatening in the case of MVE.
