Of the 6 deaths from dengue, 4 had hypertension and 1 had hematological disease


The Federal District recorded six deaths from dengue in the first 27 days of 2024. According to the Department of Health (SES-DF), among the dead, five had comorbidities, 4 being diagnosed with hypertension and 1 with a hematological disease.

Also according to the folder, the following are considered risk comorbidities for dengue: high blood pressure or other cardiovascular diseases, diabetes mellitus, chronic obstructive pulmonary disease (COPD), chronic hematological diseases — mainly sickle cell anemia —, chronic kidney disease, peptic acid disease and autoimmune diseases.

According to the epidemiological bulletin released by the department on Thursday (1/2), the patients who died were between 5 and 79 years old, five of whom were male and one female. The victims lived in Ceilândia (2), Guará (2), Estrutural (1) and Lago Sul (1).

In addition to the 6 confirmed deaths, another 24 are being investigated by the secretariat.

Other risk factors

According to SES-DF, susceptibility to the dengue virus is universal, however, there are individual risk factors. They are: age, ethnicity, presence of comorbidities and secondary infection that can determine the severity of the disease.

Younger children are at greater risk of complications due to dengue infection. Also within the most vulnerable group are people over 65 years of age, because they have a less efficient immune system, the possible existence of associated diseases and even the fact that they become dehydrated more easily.

In general, dengue has four serotypes. This means that a single person can be infected by each of these microorganisms and generate permanent immunity to each of them. In other words, it is possible to be infected up to four times

During the period when the fever decreases or disappears, most cases progress towards recovery and cure of the disease. However, some patients may experience more severe symptoms, which include bleeding and can lead to death.

Some patients may also present neurological manifestations, such as seizures and irritability. Shock lasts for a short time and can lead to death within 12 to 24 hours, or rapid recovery after appropriate anti-shock therapy.

Despite its severity, dengue can be treated with analgesics and antipyretics, under medical supervision, such as paracetamol or dipyrone to alleviate symptoms.

To complete the treatment, rest and fluid intake are recommended. In the case of dengue hemorrhagic fever, therapy must be carried out in the hospital, with the use of medication and, if necessary, platelet transfusion.
