The conditions have been right for Zika virus to spread during the warmer months of past years in Townsville, Cairns and Rockhampton, according to research led by the Australian Red Cross Blood Service.
Using temperature data from January 2015 to December 2016, the team modelled the ability of mosquitoes to spread the virus in four Queensland cities. Brisbane (the fourth city) was the only site where the risk was low.
“If locations experience outbreaks of dengue, the conditions would also be right for outbreaks of Zika,” says lead researcher Dr Elvina Viennet.
The findings emphasise the need for imported cases to be reported immediately, Elvina says.
