Learn how to identify symptoms

The growing number of dengue cases in Brazil has generated concern, with more than half a million probable cases recorded and an alarming increase compared to the previous year. Dengue hemorrhagic fever, a more serious form of the disease, is among the main challenges faced by health authorities. According to the Ministry of Health, immediate care and strict surveillance are needed to deal with this potentially fatal condition.

Identifying classic dengue hemorrhagic fever

The initial symptoms of classic dengue and the hemorrhagic form are similar, which can make early diagnosis difficult. However, between the third and seventh day of infection, specific warning signs begin to appear. A commonly used technique to distinguish severe dengue is the positive loop test, in which small red spots on the skin indicate signs of hemorrhage when the arm is tightened with a tourniquet. Other symptoms to watch out for include spontaneous bleeding in different parts of the body (mouth, nose, gums, ears or intestine), severe abdominal pain, nausea, persistent vomiting, neurological manifestations and heart failure.

Risks and complications of dengue hemorrhagic fever

Although severe dengue fever is considered rare, its complications can be devastating and even fatal. The state of circulatory shock, characterized by a sudden drop in blood pressure and multiple organ failure, is the main cause of death associated with dengue hemorrhagic fever. Excessive loss of fluids and blood due to internal bleeding can further worsen the patient's clinical condition, requiring urgent medical intervention.

Dengue prevention and control

Controlling the vector, the Aedes aegypti mosquito, is essential in the fight against dengue. The elimination of stagnant water breeding sites, where the mosquito lays its eggs, is an effective strategy to reduce the transmission of the disease. Furthermore, individual measures, such as the use of repellents and vaccination, play a crucial role in preventing dengue infection. Vaccination, available in the SUS for certain population groups and in the private sector for a wider age range, offers an additional layer of protection against the disease.

Dengue fever remains a public health challenge in Brazil, requiring a comprehensive approach that includes active surveillance, vector control measures and public awareness of the importance of prevention. O.
