Japanese Encephalitis

Japanese encephalitis virus (JEV) has recently been detected in humans, pigs, and mosquitoes in Victoria. This is the first time JEV has been detected in Victoria and other parts of South-eastern Australia.

JEV is spread to humans through the bite of an infected mosquito. JEV can cause Japanese encephalitis (JE), a rare but potentially serious infection of the brain. Most people who get infected with JEV only have mild symptoms or no symptoms at all. Therefore, you may have been infected and recovered from JEV without knowing it.

Stay Protected: Mosquito Safety Caution

Victoria’s early warning mosquito surveillance program has identified the virus in two mosquito traps in Moira Shire – the first mosquito-borne disease detections this season. It follows similar recent detections in New South Wales and a confirmed human case of Japanese encephalitis identified in Victoria in December. These findings suggest that JE virus is circulating in northern Victoria this summer. JE virus is spread to humans through bites from infected mosquitoes and can cause a rare but serious infection of the brain. Residents and visitors to northern Victoria, particularly in areas near the Murray River, are encouraged to take steps to protect themselves and their loved ones from mosquito bites.

Follow these simple and essential tips to protect yourself and your family against mosquitoes:

1. Mozzies can bite through tight clothing. Cover up: In light of increased mosquito activity, it is vital to cover up by wearing long, loose-fitting clothing, especially in areas where recent flooding has left standing water.
2. Use Mosquito Repellents containing Picaridin or DEET: Protect yourself by applying mosquito repellents to all exposed skin.
3. Limit outdoor activity if lots of mosquitoes are about: If mosquitoes are particularly active, consider spending less time outside during these periods.
4. Remove stagnant water where mosquitoes can breed around your home or campsite if you can do so safely: Regularly check and remove any standing water around your home or campsite to prevent mosquito breeding.
5. Choose mosquito-proof accommodation: When camping or travelling, opt for places with mosquito netting or screens for added protection.
6. Use ‘Knockdown’ Fly Spray, Mosquito Coils, or Plug-In Repellent Outdoors: Increase outdoor protection by using “knockdown” fly spray, mosquito coils, or plug-in repellents to help create a safer environment for outdoor activities.
7. Don’t forget the kids – always check the insect repellent label: Always check the insect repellent label for age appropriate usage. On babies, you might need to spray or rub repellent on their clothes instead of their skin. Avoid applying repellent to their hands.

Get Vaccinated against Japanese encephalitis if eligible: Vaccination is an important way to protect against JE. Vaccination is available free-of-charge for specific groups, including those living in high-risk LGAs in northern Victoria. Check your eligibility on the Victorian Department of Health website. Vaccines are available to eligible people through participating councils, GPs and local pharmacies – contact GVPHU to find a vaccine provider near you. Please note that may be a consultation fee to administer the vaccine, check with your chosen provider when you are booking.

Bookings for JE vaccination can be accessed online or by phone is available at the following local government councils websites for more information.
