Victoria’s early warning mosquito surveillance program has identified the Japanese encephalitis virus in two mosquito traps in the state’s north (Moira Shire).
If you live in or visit northern Victoria, particularly inland riverine regions and near the Murray River, you are potentially at higher risk of infection.
Japanese encephalitis virus can cause a rare but potentially serious infection of the brain and is spread to humans through bites from infected mosquitoes. A free vaccine is available for eligible people in 24 high-risk local government areas in northern Victoria. A Medicare card is not required for a free JE vaccine.
It is also important that you take measures to prevent mosquito bites.
- For the best protection, use mosquito repellents containing Diethyl Toluamide (DEET) or Picaridin.
- Apply repellent evenly to exposed skin and clothing, on top of sunscreen.
- Wear long, loose-fitting, light-coloured clothing and enclosed shoes.
- Mosquitoes breed in stagnant water, so empty containers from around your property where water can collect.
If holidaying, camping or caravaning in high-risk areas of northern Victoria:
- ensure mosquito screens are intact
- close doors and tent flaps to stop mosquitoes getting inside
- use a mosquito net if mosquito screens are not available
- try to avoid camping near wetland habitats where mosquitoes are likely breeding
Mosquitoes can spread serious disease. Know the risks. Get prepared. Stay safe.
