Virus to strike down thousands after outbreak confirmed in Queensland

Ross River fever is expected to afflict thousands of Queenslanders in coming weeks after an outbreak was confirmed in the state's south.

Figures indicate 1000 people have already been infected since the start of the year, the ABC reported.

Heavy rain high tides are being blamed for an upsurge in the mosquito population, leading to a corresponding increase in bites.

Gold Coast University Hospital infectious diseases director John Gerrard said he expected thousands more cases to emerge in coming weeks.

"The majority of people will recover within six weeks but some people will have symptoms that will last up to a number of months," Dr Gerrard said.

People who contract the virus from an infected mosquito will start to show symptoms three to 11 days later.

There is no known cure for the disease, which inflicts on its victims swollen, painful joints, rashes, fever, fatigue, headaches and muscle pain.
