The transmission of dengue occurs during the bite of a mosquito Aedes aegypti infected with viruses. After the bite, the symptoms are not immediate, as the virus has an incubation time that lasts between 5 to 15 days, corresponding to the time between infection and the onset of symptoms. After that time, the first symptoms begin to appear, which can include headache, high fever, pain in the back of the eyes and pain in the body.
Dengue is not contagious, that is, it cannot be transmitted from person to person, nor can it be transmitted through the consumption of food or water. The transmission of dengue is exclusively through the bite of the infected mosquito. The virus can also be passed from humans to mosquitoes, where the mosquito Aedes aegypti when biting a person with dengue, it acquires the virus and can transmit it to other people.
