Public health physician David Durrheim said the recent warm weather, good rainfall and king tides had resulted in excellent breeding conditions for mosquitoes responsible for spreading Ross River virus and Barmah Forest virus. 

“Good rainfall in coastal areas during the past few weeks has contributed to a rise in mosquito numbers while the warm weather allows mosquitoes to survive longer and transmit the virus to people,” Dr Durrheim said. 

“The coastal high tides last week will provide an excellent breeding opportunity for saltmarsh mosquitoes.” 

The only way to prevent infection is to avoid being bitten by mosquitoes. 

“These viruses are spread by mosquitoes that feed on animals that have the infection, so prevention depends on avoiding mosquito bites,” Dr Durrheim said. 

“The symptoms of Ross River virus and Barmah Forest virus infection include fever, skin rash, painful joints and tiredness. 

“Most people affected will have a mild illness that lasts for a few days. However, in some people joint aches and lethargy can last for months.”
