Residents and visitors to the South West region of Western Australia are being urged to take precautions against mosquito bites following the first detection of the Ross River virus (RRV) in local mosquitoes this season. The virus was identified through the mosquito surveillance program conducted by the Department of Health, highlighting the ongoing risks associated with mosquito-borne diseases.
Dr Andrew Jardine, Managing Scientist at WA Health, emphasized the importance of the surveillance program as an early warning system. “The alerts advise people of the increased risk of disease, and they can take appropriate protective measures to avoid mosquito bites,” he noted. RRV is recognized as the most prevalent mosquito-borne virus in Western Australia, with symptoms that can significantly affect quality of life.
As of now, there have been 24 notifications of RRV reported in the state since July 2023, including six cases from the South West region. Symptoms of RRV include joint pain, muscle aches, skin rashes, fever, fatigue, headaches, and rashes that can persist for weeks or even months. The health authorities are particularly concerned about the impact of these symptoms on the daily lives of those affected.
Health Recommendations for Prevention
Dr Jardine’s comments serve as a timely reminder for residents to ensure their homes are protected against mosquitoes. He advises the public to wear suitable clothing and use effective insect repellent when outdoors. “There is no vaccine, cure, or specific treatment for RRV or the Barmah Forest virus (BFV), so it is crucial that people take care to prevent being bitten by mosquitoes,” he stated.
In addition to RRV, the Barmah Forest virus has also been detected in mosquitoes collected from the South West region recently. However, there have been no reported human cases of BFV in the area since May.
For those seeking guidance on mosquito avoidance, information is available through HealthyWA. The recommendations include covering up exposed skin, using repellents, and maintaining clean surroundings to eliminate potential mosquito breeding sites.
As the summer months approach, the health department continues to monitor mosquito populations and advises the community to remain vigilant in protecting themselves against these viruses. By taking proactive steps, individuals can significantly reduce their risk of contracting diseases spread by mosquitoes.
