Increased risk of Ross River virus

22/12/25

Holiday makers and residents in Gippsland are being urged to protect themselves from mosquito bites following recent detections of Ross River virus in mosquito surveillance traps.

The Victorian Arbovirus Disease Control Program has identified Ross River virus in multiple mosquito traps in Wellington and East Gippsland Shires in recent weeks. Councils have implemented mosquito control operations on their land, but with warmer weather increasing mosquito breeding, mosquito levels can be difficult to manage.

With an expected increase in visitors to regional Victoria over the coming weeks, Victorians are reminded that simple precautions can significantly reduce the risk of infection.

Ross River virus is spread through the bite of infected mosquitoes. While many people do not develop symptoms, some may experience fever, joint pain and swelling, muscle aches, fatigue or rash. Symptoms can last for weeks or months in some cases.

There is no vaccine or specific treatment for Ross River virus. Preventing mosquito bites is the most effective way to reduce the risk of infection.

People travelling throughout Victoria this holiday season are advised to wear long, loose-fitting, light coloured clothing, use mosquito repellent containing picaridin or DEET on exposed skin, and limit time outdoors when mosquitoes are most active, particularly at dawn and dusk. Those travelling over the Christmas/New Year period are advised to pack repellent before leaving home, as stocks may be limited in smaller country towns.

Holiday makers should ensure accommodation, caravans and tents have intact mosquito screens, use mosquito coils and camp some distance from the edge of rivers/lakes, where mosquitoes breed.

Anyone who develops symptoms consistent with Ross River virus infection should seek advice from their GP.
