The dengue virus is an infectious disease caused by the dengue virus (DENV 1, 2, 3, 4 or 5), and in Brazil there are only the first 4 types, it is transmitted by the bite of the female mosquito Aedes Aegypti especially in the summer and in periods of rain.
Dengue symptoms include fever, tiredness, headache, pain in the back of the eyes, there is no specific treatment, and rest is recommended, painkillers, anti-thermal medication like Dipyrone, and keeping well hydrated. However, some people may develop a severe form of the disease, called severe dengue, characterized by vascular leakage, severe bleeding and organ failure, being potentially fatal.
To diagnose the severity of the dengue fever, the doctor does tests such as the tie and blood test, to count platelets and red blood cells. These tests are only requested when dengue complications are suspected.
How long does dengue fever last
The symptoms of classic dengue fever last on average 7 days, depending on your general state of health before becoming ill. In general, healthy adults usually recover from this disease in about 2 or 3 days, because the body is more prepared to fight the virus.
However, children, pregnant women, the elderly, or people with weakened immune systems, such as those infected with AIDS and who are undergoing cancer treatment, can take up to 12 days to recover from dengue fever, and so it is important for you to rest to help with the process of healing.

Hemorrhagic dengue fever
Symptoms of hemorrhagic dengue last on average 7 to 10 days and the signs of shock can start 3 to 5 days after the onset of these symptoms, being the most severe phase of this type of disease.
The initial symptoms of hemorrhagic dengue are very similar to those of the classic version of the disease, but with a greater severity, as they can cause changes in blood coagulation. Nasal, gingival, urinary tract, gastrointestinal and uterine bleeding are common, which are a reflection of bleeding in the small vessels of the skin and internal organs. In more severe cases, dengue can lead to complications such as severe dehydration, liver, neurological, cardiac or respiratory problems.
Therefore, it is very important to be alert to the symptoms, because in hemorrhagic dengue the clinical condition worsens rapidly, which can lead to shock and death within 24 hours. Therefore, a doctor should be urgently sought so that appropriate treatment is started as soon as possible.
