After the bite, the symptoms are not immediate, as the virus has an incubation time that lasts between 5 to 15 days. After that time, the first symptoms start to appear, which can include headache, high fever, pain in the back of the eyes and pain in the body.
Dengue is a disease that is not contagious, that is, it cannot be transmitted from person to person, nor is it transmitted through water or food. The virus can also be passed from humans to mosquitoes, with contamination occurring when an uncontaminated mosquito bites an individual with dengue. In these cases, the mosquito becomes contaminated and can transmit the disease through its bite. In addition, in case of pregnancy, when the woman is bitten and contaminated, her baby is not, therefore there is no vertical transmission of this disease.
