According to a bulletin recently released by the Ministry of Health, Brazil recorded 382 deaths from dengue this year until May 21. During the year 2021, 246 deaths were recorded. These data point to a significant increase in deaths caused by the disease this year. With regard to cases of dengue, according to a bulletin from the same ministry, published in early May, the country recorded an increase of 113.7% in cases of the disease (542,038 probable cases) from 2 January to 23 April in relation to for the same period. period the previous year. The regions most affected by the occurrence of dengue are the Midwest, followed by the southern, southeastern, northern and northeastern regions.
“The data indicate an outbreak of the disease well into the autumn. In general, summer is the best time for red lights to turn on compared to cases of dengue, zika and chikungunya. High temperatures and rainfall promote the increase in the vector population with a double result: in contact with rainwater, eggs laid weeks or months ago can hatch and give rise to thousands of new migratory mosquitoes (Aedes aegypti). At the same time as the rain, the supply of breeding grounds for Aedes females to lay their eggs is increasing, ”explains Dr. Márcia Lima Dantas, Infection Medicine Consultant at Minuto Saudável.
According to the doctor, the correct diagnosis is made through clinical examination followed by laboratory tests. “Especially around dengue, the infection occurs in three phases. The febrile phase, which occurs with an increase in viral volume, is associated with nonspecific symptoms. This phase resolves itself in three days. In the critical phase, there is an increase in the permeability of the body’s vessels, which can trigger complications. It is at this stage where the fever no longer appears that there may be signs that the infection is developing into a serious condition, so medical follow-up is important. And in the recovery phase, there is an increase in the amount of urine and the resolution of symptoms that are characteristic of the critical stage “, describes Dr. Marcia.
Symptoms and treatment of dengue
The symptoms are high fever (39ºC to 40ºC), sudden onset, associated with headache, fatigue, muscle aches, in the joints and behind the eyes, redness of the body (exanthema) and itching. “Loss of appetite, nausea, vomiting and non-bulky diarrhea may be present but are less common,” explains the specialist.
“Medical treatment should be started as soon as the first signs appear, because with proper professional monitoring it is possible to identify signs of worsening of the disease. It is important to point out that in the case of dengue not recommended the use of acetylsalicylic acid (ASA), due to the risk of bleeding. Medication must be prescribed by the doctor. You need to rest completely and drink plenty of water, ”says the specialist.
With the escalation of the dengue outbreak across the country, measures to limit the spread of the dengue mosquito are very important and must be adopted by all. It should be observed places that can accumulate stagnant water, such as poorly covered water tanks, abandoned cars and tires and even in debris and leaves on streets and sidewalks. In this sense, it is necessary to keep boxes, tubs and barrels of water well covered and put the waste in plastic bags, with the trash always well closed, without accumulation of water.
In addition, glass or plastic bottles should be upside down; the small plates or pots should have sand up to the rim; gutters need to be cleaned frequently; Old tires should be stored in a covered place, protected from rain. Neighbors, friends and relatives must be allies in the fight against mosquito breeding grounds Aedes aegypti.
