WA Health issues Ross River Virus warning

WA Health has issued a public health warning after Ross River Virus was detected in mosquitoes collected at Swan River in Crawley recently.

The virus was detected in mosquitoes collected by City of Perth Council as part of a WA Health-coordinated mosquito surveillance program. 

Acting Director of Environmental Health, Dr Peter Gray said virus activity had recently been identified at a trapping site in Pelican Point, Crawley.

“We are encouraging people to take steps to prevent mosquito bites, particularly over the long weekend when people are more likely to be outside socialising,” Dr Gray said.

He said there had been increased mosquito activity in recent weeks due to an extended period of environmental conditions favourable to mosquito breeding, including persistently high tides and warmer weather.

Mosquito management is carried out by local governments in collaboration with WA Health in areas with a recognised risk of mosquito-borne diseases.

“However, river goers are reminded not to rely on mosquito management programs alone to control all mosquitoes,” Dr Gray said.

“People need to take their own precautions to avoid mosquito bites.

“Ross River virus is the most common mosquito-borne virus in WA and symptoms can be debilitating.

“There is no vaccine, cure or specific treatment for RRV, so it is important that people take care to prevent being bitten by mosquitoes.

“Check if your home is mosquito-proof and make sure you have appropriate clothing and effective repellent, to keep you and your family safe.” 

Symptoms of RRV infection include painful or swollen joints, sore muscles, skin rashes, fever, fatigue and headaches, lasting for weeks to months.

The only way to diagnose whether you have a mosquito-borne disease is to visit your GP and have a specific blood test.
