Symptoms of Dengue Fever

Do you know…•Dengue fever and dengue haemorrhagic fever are the most common mosquito-borne viral disease in the world.
•Only the female mosquito feeds on blood. This is because they need the protein found in blood to produce eggs. Male mosquitoes feed only on plant nectar.
•The mosquito is attracted by the body odours, carbon dioxide and heat emitted from the animal or humans.
•The female Aedes mosquito searches for suitable places to lay their eggs.
•Aedes are day-biters, most active during dawn and dusk.
