What é dengue (and how long it lasts)

Dengue is an infectious disease caused by the dengue virus (DENV 1, 2, 3, 4 or 5). In Brazil there are the first 4 types, which are transmitted by the bite of the female Aedes aegypti mosquito, especially in the summer and in the rainy season.

The symptoms of dengue include fever, tiredness, headache, pain in the back of the eyes and there is no specific treatment, being recommended rest, analgesics, antipyretics such as dipyrone, and hydration. However, some people can develop a serious form of the disease, called severe dengue, characterized by vascular leakage, severe hemorrhage, and potentially fatal organ failure.

The diagnosis of dengue severity is made by the doctor through tests such as the snare test and blood test for platelet and red blood cell counts, which are tests that are only requested when there is a suspicion of dengue complications.

Dengue duration time

Dengue lasts an average of 5 to 7 days, however, this period may vary depending on the type of infection:

1. Classic Dengue

The symptoms of classic dengue last an average of 7 days, depending on the patient's he alth status before becoming ill. In general, he althy adults usually recover from the disease in just 2 or 3 days, as the body is better prepared to fight the virus.

However, children, pregnant women, the elderly or people with an altered immune system, as in cases of AIDS and cancer treatment, the symptoms of dengue can take up to 12 days to resolve, and it is important to rest and proper nutrition to speed up the healing process. Here's what eating should be like to recover faster.

2. Hemorrhagic Dengue

The symptoms of dengue hemorrhagic fever last, on average, 7 to 10 days and the signs of shock may 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 dengue hemorrhagic fever are very similar to those of the classic version of the disease, but with a greater severity, as they cause changes in blood clotting. Bleeding from the nose, gums, urinary system, gastrointestinal tract and uterus is common, which is a reflection of bleeding from small vessels in the skin and internal organs.

In the most serious cases, dengue can cause complications such as severe dehydration, liver, neurological, cardiac or respiratory problems. Know all the complications and sequelae that can arise.

Thus, it is very important to be aware of the symptoms, because in dengue hemorrhagic fever the clinical picture worsens rapidly, and can lead to shock and death within 24 hours. Therefore, assistance should be sought urgently, so that appropriate treatment is given as soon as possible.
