Dengue fever is a severe viral disease, transmitted by the infective bite of aedes aegypti mosquito. The mosquitoes are identified by the black and white stripes on their bodies. The peak biting hours are dusk and dawn.
A person develops disease after five-six days of being bitten by an infective mosquito. It can occur in two forms: dengue fever and dengue haemorrhagic fever (more severe form that may cause death).
