Dengue outbreaks hit Far North Queensland
Since late last year there have been two outbreaks in the state's north – 58 cases in Cairns and 17 in Port Douglas.
Fourteen new cases have been reported in the past week.
Cairns Tropical Public Health Unit director Dr Richard Gair said the outbreak is significant but not as bad as an outbreak in 2009 when more than 1000 people were infected.
"I would say it's a significant outbreak... but it's about what we'd expect based on recent numbers over the last few years," he told AAP.
"We've got a little more this year than we did last year, but I don't know what the final number is going to be."
Three of those infected have been hospitalised.
Dr Gair said the virus was likely brought to the region by people infected in Indonesia or Thailand.
Health authorities are trying to contain the outbreaks by spraying mosquitoes and removing mosquito breeding spots where outbreaks have occurred.
