Mosquitoes are the mediators of dengue fever transmission from the body of an infected person to a healthy person. After a mosquito bites a person infected with dengue fever, the virus from the infected person's blood will be transferred to mosquito cells. 12 days is the time from when a mosquito sucks blood from an infected person until the mosquito can transmit the disease to a healthy person. During this time, in the mosquito's body, the viruses multiply, spreading to the cells until they reach the mosquito's salivary glands. At that time, if the mosquito bites a healthy person, it will transmit the dengue virus to the healthy person's body.
