I have dengue fever, what should I do?

Infectious disease specialist Joleval Ribeiro points out that people diagnosed with severe dengue fever, called dengue hemorrhagic fever, may continue to have symptoms and suffer sequelae, such as heart failure and myocarditis — an inflammation of the heart muscle tissue. Jollival also mentions that there may be consequences for the brain.

Dengue hemorrhagic fever

Health changes particularly affect patients who have had dengue hemorrhagic fever. Anchieta Hospital tropical disease specialist and infectious disease specialist, Manuel Palacios, explains how classic dengue develops into hemorrhagic fever.

Spontaneous bleeding: from the gums, nose and gastrointestinal tract

Severe and continuous abdominal pain

Persistent vomiting

Lethargy or irritability

Dengue fever causes internal dehydration due to fluid loss, which leads to thickening of the blood and shedding of platelets – factors that increase the risk of bleeding, explains Intensive Care Doctor at Santa Marta Hospital, located in Taguatinga Sul in the Federal District, Adele Vasconcelos.

“The development of dengue fever into hemorrhagic fever depends from one organism to another. We consider dengue hemorrhagic fever only if the patient has some type of bleeding, whether it is in the eyes, nose, mouth, urine, feces, and sometimes even in the head or brain attack.

Regarding the consequences of severe dengue, organs such as the heart, kidneys, liver and brain can be affected. The teacher from Jama, in the Federal District, Glaucia Ferreira Matos, 45, fell ill in March this year. She said that in addition to the effect of dengue on her immunity, she was investigating kidney and liver problems.

“Dengue has seriously affected my liver, and therefore my kidneys as well, and I am now undergoing follow-up, blood tests, blood counts, and some more specific tests for monitoring, because I was experiencing symptoms that I had never experienced before in my life,” the teacher says. With dengue fever.
