Only the female mosquitoes transfer the virus. This female mosquito is a daytime biter, both inside and outside homes. It is most active in the hours after sunrise and before sunset.
Dengue fever mosquitoes thrive in areas with stagnant water, including puddles, water tanks, containers and old tires.
Lack of proper sanitation and regular garbage collection also contribute to the spread of these mosquitoes.
It may also be noted that dengue fever is usually rampant during the monsoon and from September to December.

Symptoms of dengue fever usually begin after 5-6 days of infection. Also, sometimes, these symptoms are mild and can be mistaken for those of the viral infection and flu.
