Advancement of dengue still requires attention in Mogi das Cruzes

DIFFICULT Tires with water are breeding grounds for the Aedes aegypti mosquito. (Photo: file) Although the attention of health authorities and the population in recent weeks has been focused on the rapid spread of the new coronavirus, which mainly affects China, but has suspected cases in Brazil, the main concern in Mogi das Cruzes and in the entire state of São Paulo is the advance of dengue, including cases of type 2 of the disease. A new evaluation of larval density (ADL) is being concluded, with the compilation of the collected data, for dissemination next week, portraying the situation in the city at the beginning of the year. The municipality has three dengue cases registered since the beginning of 2020 and others 15 awaiting the results of tests sent to the Adolfo Lutz Institute, in the Capital. Throughout the past year, there were 106 confirmations and other 70 notifications of suspected diseases that still await the test report. However, according to the Municipal Health Secretariat, the city has no serogroup identification – a nomenclature used to identify the type of dengue, so registered cases can be of any type of disease. But doctor Tereza Nihei, from the Epidemiological Surveillance of the Municipal Health Department, does not rule out the possibility of registering cases of dengue type 2, as well as any other virus that may circulate. “Mogi has had dengue cases for some time, and each year, the Department of Health makes an analysis of the previous year, of the State’s epidemiological situation and has been organizing itself, with an update of the municipal plan for arbovirus infections to cope mainly with dengue, which is the most prevalent disease in our municipality so far ”, says the doctor. Tereza explains that dengue and the new coronavirus present totally different situations and conditions, but that both require attention. “These are diseases that have different forms of transmission. So it is complex to make any kind of comparison. In China, we have information that the new coronavirus has a great capacity for propagation, but in Brazil we do not have subsidies to make any type of forecast or estimate ”, he informs. Also according to the doctor, dengue is an endemic disease, which gives immunity to each type, so the susceptibility depends on the serogroup that is circulating. “For the municipality that has no history of major epidemics, we have many people even though they did not have dengue or became infected with few types. The State Department of Health has alerted us to a year of greatest concern, precisely because of the change in the circulating serogroup since last year, therefore, we must prepare for the next months, which is the period with the greatest record of cases ”, he explains. As dengue is transmitted by the bite of the Aedes aegypti mosquito, Tereza says that the solution is to reduce these agents through the care of everyone in the elimination of possible breeding sites. “Dengue cases will only be reduced as mosquitoes are no longer able to proliferate. Without breeding grounds, such as accumulated water, we will not have a mosquito, and consequently we will reduce dengue cases and who knows, we may even be able to eliminate them ”, he emphasizes. Coronavirus Doctor Tereza Nihei points out that so far, there is no confirmation of cases of the new coronavirus in Brazil, but according to the World Health Organization, all countries must monitor and take measures to prevent the spread of the disease. “Therefore, the population must protect themselves through care to avoid respiratory transmission diseases, with hand washing, use of gel alcohol, avoiding places of large agglomerations, using disposable tissues, among others,” he warns. Combating Aedes depends on care According to veterinarian Jefferson Renan de Araújo Leite, from the Zoonosis Control Center of Mogi das Cruzes, the biggest obstacle to ending dengue lies precisely in the difficulty of containing Aedes aegypti, which can be a vector of a series of diseases. “In addition, the lack of an effective vaccine also contributes to the progress of dengue and other arboviruses. It takes a mutual effort, public power and population, to control Aedes, since the environmental and climatic conditions are favorable to the insect and it is extremely adapted to live in the urban environment ”, he advises. Environmental care, in the evaluation of Leite, is very important, since many problems are still encountered with the irregular disposal of residues that serve as reservoirs for the mosquito. “We have problems with the accumulation of material for recycling, improperly stored, careless with swimming pools, water tanks and other water reservoirs”, says the veterinarian.
