Causes of dengue fever
Dengue fever is a mosquito-borne tropical disease caused by the dengue virus.
Symptoms typically begin three to fourteen days after infection...
Dengue fever is caused by any one of four types of dengue viruses spread by mosquitoes that thrive in and near human lodgings.
When a mosquito bites a person infected with a dengue virus, the virus enters the mosquito.
When the infected mosquito then bites another person, the virus enters that person's bloodstream.
Dengue is spread by several species of female mosquitoes of the Aedes type, principally A.
Dengue virus (DENV) is the cause of dengue fever.
It is a mosquito-borne, single positive-stranded RNA virus of the family Flaviviridae; genus Flavivirus.
Five serotypes of the virus have been found, all of which can cause the full spectrum of disease.
Some species of this genus transmit serious diseases, including dengue fever, yellow fever, the Zika virus, and chikungunya.
In Polynesia, the species Aedes poly nesiensis is responsible for the transmission of human lymphatic filariasis.
