THE density of mosquito-breeding places will rise exponentially two or four weeks after the flooding, according to the national advisor on communicable diseases, Dr Mike Kama
"We can contemplate that the flooding may wash away mosquito larvae," Dr Kama said.
"It is projected to decrease because of flooding and then after two weeks or four weeks of still water remaining, mosquito breeding areas will just rise exponentially — that's for mosquito only, not dengue as a disease."
Dr Kama said dengue fever would continue to be a risk.
"Dengue continues to become a risk, especially at evacuation centres, but our house inspectors are onto that.
"That is one area that we have already targeted — the evacuation centres. The clean-up should happen all around them — that's the plan and strategy."
