Ross River Virus Cases Quadruple in South Australia in 2025: A Personal Story of Struggle and Awareness
In 2025, South Australia witnessed a startling surge in Ross River Virus (RRV) cases, quadrupling from 25 in 2024 to 106. This alarming trend is not just a statistic but a personal tragedy for Bec Powditch, a 44-year-old Australian who contracted the virus last year. Her story highlights the insidious nature of RRV, which spreads through mosquitoes and can leave victims with severe, long-lasting joint pain.
Powditch's experience began on the Australia Day long weekend at her family's shack along the River Murray. Despite being a familiar target for mosquitoes, she was shocked to develop a red rash on her arms and legs a week later. Within days, she faced excruciating joint pain in her wrists, knees, and feet, a pain she likened to being smashed with a hammer. This was a stark contrast to the mild symptoms she had initially expected.
After researching her symptoms, Powditch sought medical attention and was diagnosed with RRV. Her initial doctor's response was dismissive, offering only over-the-counter pain relievers, which had no effect. It was only after joining online support groups and consulting another doctor that she received a proper diagnosis and was prescribed steroids, which she took for five months.
One year later, Powditch still grapples with the pain, feeling far from her pre-infection self. Her experience underscores the profound impact of RRV, which can debilitate individuals for extended periods, even after recovery.
The virus, transmitted by mosquitoes from infected animals to humans, is widespread across Australia. There are no antiviral treatments or vaccines to prevent infection. In 2025, South Australia recorded 106 cases, a fourfold increase from 2024, according to SA Health's surveillance data. The Riverland region, in particular, saw a cluster of cases, but RRV has been detected across the state.
Dr. Chris Lease, acting chief public health officer, noted that while the number of cases in 2025 was four times that of 2024, previous years had seen similar trends. He attributed the increase to factors like heavy rainfall, more breeding sites, and warmer weather, all of which boost mosquito populations. As the numbers rise again in late 2025 and into 2026, Dr. Lease emphasizes the importance of preventive measures such as covering up, wearing long clothing, using mosquito repellent, and monitoring local environments.
The spread of RRV is not limited to large waterways. Dr. Lease stresses the need for vigilance in all areas, citing the release of the 'Mozzies Suck' campaign to raise awareness. The campaign aims to educate the public about the dangers of mosquito-borne diseases, including RRV, which can be debilitating but not fatal.
The conversation around RRV has been overshadowed by the introduction of new mosquito-borne diseases like Japanese Encephalitis, which has a high mortality rate. Professor Craig Williams of Adelaide University notes that while these new viruses are deadly, they tend to overshadow the more common but equally debilitating infections like RRV. He hopes the newly established Australian Centre for Disease Control will play a pivotal role in setting national policies and strategies for disease surveillance, including RRV.
Bec Powditch's story is a call for increased empathy and awareness about RRV, to prevent others from enduring the pain she has experienced. Her hope is that by sharing her story, she can contribute to a more informed and compassionate response to this growing health concern.
