Campaspe and Moira Shires, Greater Shepparton home to Ross River virus

Health authorities are urging people to be on high alert for Ross River virus. Here are the hot spots across the state.

Victorians are still being advised to remain on high alert for Ross River virus and protect themselves where possible.

Figures from the Department of Health have revealed 12 cases of the disease have been recorded in Victoria since November 1 last year.

A health warning on Christmas Eve advised Victorians the virus had been detected in the local government areas of Campaspe Shire, Moira Shire and Greater Shepparton City Council.

“There is increased risk that people living in or travelling to these areas may be infected by mosquitoes carrying Ross River virus,” the warning said.

Mosquito numbers are very high along parts of the Murray River between Gunbower, east of Echuca, and Yarrawonga with recent weather described as favourable for biting and breeding.

“Since the start of the mosquito season in November, routine mosquito surveillance has been in operation to detect Ross River virus in areas of the state where mosquito-borne diseases are most common,” a Victorian Government spokesperson said.

“Ross River virus is endemic throughout most of Victoria, and the risk of catching it is very real, particularly in many rural and regional parts of the state and popular coastal tourist areas, highlighting the importance of taking action to Beat the Bite.

“The department partners with a number of rural and regional councils to undertake mosquito surveillance and management during the annual mosquito breeding season from November to April.”

Ross River virus can take up to three to nine days for symptoms to occur after exposure — with some cases taking up to 21 days.

It’s recommended to wear long, loose fitting clothes, use repellents containing picaridin or DEET on exposed skin and try to limit outdoor activities if lots of mosquitoes are around.

There is currently no vaccine available commercially to protect against Ross River virus.
