Health Alert: Ross River Virus Detected in the City of Kalamunda

17 March 2025 2:48 PM

The City of Kalamunda is urging residents to take precautions against mosquito bites following the confirmation of a Ross River Virus (RRV) case in an adult who acquired the infection locally.

Ross River Virus is a mosquito-borne disease that can cause symptoms such as painful or swollen joints, sore muscles, skin rashes, fever, fatigue, and headaches. While symptoms can persist for weeks or even months, early diagnosis is key to managing the illness. Anyone experiencing these symptoms is encouraged to visit their GP for a blood test to confirm the presence of the virus.

Mayor Margaret Thomas emphasised the importance of community awareness: “While there is no need for alarm, it is essential that we all take steps to protect ourselves and our loved ones from mosquito bites. Simple actions, like wearing protective clothing and using insect repellent, can make a big difference.”

“As residents, we all have a role to play in reducing mosquito breeding grounds on our properties. This includes properly maintaining water sources, such as unused swimming pools and spas, as untreated stagnant water provides an ideal breeding environment for mosquitoes.”

The City is working closely with the Department of Health to monitor the situation and implement mosquito management strategies. The Department has launched its ‘Fight the Bite’ campaign to educate individuals on simple ways to prevent being bitten by mosquitoes, reduce breeding around their homes and holiday accommodation, and minimise the risk of mosquito-borne disease transmission.

The City also runs its Annual Mosquito Control Program from October through March, as part of its Mosquito Management Plan (MMP). Management measures under the plan include monitoring mosquito populations through trapping, draining, and baiting stormwater gullies to prevent larvae from developing into adult mosquitoes, and much more.
