An outbreak of dengue fever has been confirmed in Cairns, with experts urging locals across Far North Queensland to be on the lookout for symptoms and mosquito breeding sites. 

Two cases of dengue have been confirmed in the Cairns suburb of Edmonton, with a third likely suspected. 

It is believed the victims of the disease were infected by someone outside of Cairns. 
Dengue is spread by the Ades Aegypti mosquito, which is easily identifiable by the white markings on its legs. 

The mosquito's larvae develop in shallow, still water. 

Residents are urged to check their properties and tip out water sitting in potplant dishes, tyres and other receptacles to help cut down on mosquito numbers.
