In the light of day, he is not afraid of agglomerations and even prefers the movement of the city to the calm of the countryside. Measuring less than an inch, the black-bodied, white-striped villain feeds on human blood, attacking its victims usually at dawn and dusk – but as opportunistic as it is, it also acts in nocturnal attacks. . The “beast” in question has a name and a first name: Aedes aegypti.
The mosquito is responsible for the transmission of zika, chikungunya and dengue, which, by the way, is well known to the inhabitants of the western region of Paraná. Even if the epidemiological situation of the disease is still “comfortable”, it is beginning to cause concern in the 20th Regional Health Department.
According to data updated on Wednesday (16), the regional has 152 confirmed cases of dengue in the 18 municipalities, which are Assis Chateaubriand, Diamante d’Oeste, Entre Rios do Oeste, Guaíra, Marechal Cândido Rondon, Maripá, Mercedes, Nova Santa Rosa, Ouro Verde do Oeste, Palotina, Pato Bragado, Quatro Pontes, Santa Helena, São José das Palmeiras, São Pedro do Iguaçu, Terra Roxa, Toledo and Tupãssi.
“Given the figures presented in the reports, the situation is under control in the 20th Regional Health Department. By analyzing the historical series, the indices are below expectations for the period,” said the head of the Health Surveillance Division, Felipe Hofstaetter Zanini.
In Jornal O Presente, he points out that the region is endemic, so every year there are cases of dengue fever. “What we have to look at is how to handle the situation. We hope that this (the current epidemiological situation, which is comfortable) does not accommodate the teams of the municipalities and the population so that there is no setback, ”he points out.
in the municipalities
Nova Santa Rosa has 95 cases and is the municipality with the most dengue confirmations in the 20th regional, with an incidence of 206 cases per 100,000 inhabitants (in an article published on Friday 18, the municipality already had 334 cases – to verify). Next is Santa Helena, which has 16 cases and an incidence of 49 per 100,000 population. The third municipality with the most cases is Guaíra, with 14 registrations and an incidence of 12.
Mercedes occupies 4th place in the ranking of confirmed cases of dengue in the Regional, with seven cases. However, the incidence rate is the 2nd highest (108 per 100,000 inhabitants).
A little over a month ago, Marshal Rondon was the town with the most dengue fever cases in the 20th Regional, but the situation has remained stable and the number has fallen from three to four.
On the other hand, some municipalities still do not have confirmed cases of dengue fever: Diamante D’Oeste, Ouro Verde do Oeste, Pato Bragado, São José das Palmeiras, São Pedro do Iguaçu, Terra Roxa and Tupãssi.
According to Zanini, there are occasional situations of epidemics in the municipalities. “We are on alert, but we also realize that it is possible, with the work and responsibility of the manager and the population, to maintain control,” he says.
The intensity and evolution of epidemiological conditions are variables that must be closely monitored by the municipalities, estimates the head of the health watch division of the 20th regional. “Damage is less when vector control strategies are permanent and the structure and flows of care are clear to management, health teams and the population. We believe that what has been experienced during the epidemiological year 2019/2020 has prepared us for this confrontation, ”he believes.
Do I have dengue fever?
High fever, signs of dehydration, red spots on the skin, pain in the body, eyes and joints. These are the classic symptoms of dengue fever, but, according to Zanini, it is necessary to carry out additional tests for the diagnosis. “There are ‘false positive’ test reports for Covid-19 and dengue fever. So confirmation is important to have the most appropriate clinical medical conduct,” he guides.
The contact of the population with the health team is an essential tool for the control of dengue fever in the communes. “It is essential that citizens seek treatment, both so that their follow-up is adequate and that the clinical state does not evolve into a serious condition and so that their positivity is notified. With registration, epidemiological surveillance teams and endemic teams can define strategies to control the transmission of the disease by location,” he explains, adding that the actions of chemical blocking, research and elimination of breeding sites and cleaning of trawlers reduce the infestation of Aedes. vector.aegypti.
Nova Santa Rosa hasn’t had such a high number of cases in more than two years
According to the Secretary of Health of Nova Santa Rosa, Deputy Mayor Noedi Hardt, the current epidemiological scenario of dengue fever in the municipality represents a challenge, precisely because it coincides with the Covid-19 pandemic. “We haven’t had such a high number of cases in over two years. Unfortunately, we are experiencing this situation at the moment,” he laments.
Despite the spike in dengue fever, Hardt says prevention activities never stopped. “Last year we made more than four trawlers and this year we have already recovered more than 11 rubble trucks. Our work has never stopped. Visits were made by endemic agents, especially at strategic points, that is to say in the most critical places, in addition to orientation in schools, “he commented, developing “Right now, we’re blocking the whole city with a coastal pump passing through all the streets.”
He says the whole population must come together to eliminate the mosquito. “We ask the population to help us and collaborate with us, to clean their backyards and to organize themselves so that there are no breeding sites for Aedes aegypti”, he urges.
A dengue epidemic is not excluded in Saint Helena
Santa Helena Health Secretary Daltro Alexandre Neis told the O Presente newspaper that the scenario is an alert in the municipality. “Our current LIRAa is 8.1%, and that recommended by the Ministry of Health is 1%. Despite all the task force led by the endemics team, we must indeed be concerned about the high rates of positive tests for the disease. There are 16 positive cases and more than 100 awaiting test results,” he reported.
As in 2021, the period of rains and high temperatures is conducive to the proliferation of mosquito epidemics and the epidemiological situation seems to be worsening. “We are heading towards a dengue epidemic scenario, as notifications and the demand for care in health facilities are constantly increasing,” he underlines.
“We did our homework”
The secretary says that even during the pandemic, the work against the mosquito has not stopped. “It’s been a long time since Santa Helena has gone the year without any confirmed cases of dengue fever. Thanks to the work of the endemic agents, we started 2022 with no confirmed cases. At the end of 2021, the team led a great mobilization to clean up public buildings , notifying and sanctioning the municipal secretaries who had not taken the measures to prevent and eliminate the dengue epidemics observed by the team”, he recalls.
He emphasizes that the municipality has done its homework and that it is up to the population to do its part in terms of prevention. “The municipality has 19 environmental officers, a number well above what is recommended by the Ministry of Health. In addition, we have the support of an outsourced team, responsible for collecting waste and unusable materials that can accumulate water. With the first confirmed cases of the disease, attention has been redoubled in the most critical areas with trawlers and population councils. In the early morning and early evening, agents carry out the blocking with insecticides to ensure the safety of the population of the localities with notifications”, he informs, modifying that the mobilization will be extended throughout the municipal territory.
As for the people of Santa Helena, Neis says a few minutes of grooming a day can make a difference in preventing the mosquito from spreading. “Our legislation allows for fines for citizens who fail to meet their obligation to eliminate dengue outbreaks. At the moment, we need a working group between the Public Power and society so that our health system does not collapse, ”he concludes.
