In just over two months, Uberlândia registers 178 probable cases of dengue

Written by admin

Frequent during the summer, the rainy season warns against the proliferation of the Aedes aegypti mosquito, which transmits diseases such as dengue fever, zika and chikungunya. According to the State Department of Health (SES-MG), Uberlândia has 178 probable cases of dengue, recorded from January to March 9 this year. The number is almost 20% lower than that recorded in the same period in 2021.

Also according to the agency, the cities of Triângulo Mineiro and Alto Paranaíba that have registered the most probable cases of the disease are Patos de Minas (204), Uberlândia (178) and Uberaba (174). In the state of Minas Gerais, there are 23,193 probable notifications of the disease, with more than 15,000 already confirmed. Additionally, eight deaths have been recorded as a result of the virus, but no fatalities have been reported in the city.

Data presented by SES-MG shows that Uberlândia experienced a 19.4% drop in the rate of probable dengue cases. During the same period last year, the municipality had registered 221 suspicious notifications of the disease. According to Silvia Nunes Szente Fonseca, infectiologist and pediatrician, we must continue with the necessary care to reduce the circulation of the mosquito.

“At the moment it is raining a lot. Aedes aegypti needs some standing water to lay its eggs. The dengue mosquito has adapted very well to cities and large centers. You have to be careful and keep an eye on the garden, on the porch, in the swimming pool. A pet bottle cap that is upside down and has water in it can be a breeding ground for the mosquito,” he explained.

For the health professional, it is important that the population is made aware of the dangers of diseases transmitted by mosquitoes. According to her, prevention must be done in a methodical way, in the daily life of the population. She explains that once Aedes aegypti has adapted to an environment, it is virtually impossible to stop it.

“It is even necessary to monitor the animal’s water pot, so it is important to wash it constantly. Our biggest task as citizens is to try to reduce the mosquito population. The person can even use repellent, but people forget that they can be bitten by the mosquito inside the house. Aedes aegypti is not like the mosquito, which makes that little noise. It’s a very insistent mosquito and the bite doesn’t hurt, so it’s hard to control.”

According to Silvia, dengue usually starts with a high fever, pain behind the eyes, headaches and flushing all over the body. She says the infected person may still have stomach pain and vomiting. One of the biggest problems caused by the disease, she says, is dehydration.

As the infectiologist says, it is important to hydrate with water, serum or even isotonic drinks, because they are rich in mineral salts. “We often see dehydration, through sweating and vomiting. But internal dehydration can be a problem, because even if we don’t see it, it affects the heart and especially the kidneys. If the person does not replace it, dengue fever can progress to serious forms”, warns the doctor.

Also according to Silvia Nunes, many people confuse the symptoms of dengue fever with the flu and covid-19. She explains that any illness with respiratory symptoms eliminates the possibility of having been infected by the dengue mosquito.

“The flu begins with classic respiratory symptoms such as a runny nose, sneezing, coughing and sore throat. Covid has shortness of breath in addition to all mentioned. Dengue can make you short of breath when it’s advanced, but with a different mechanism. It is not the lung that is attacked, it is quite different”.

Despite the drop in the number of probable dengue cases in Uberlândia, the professional believes in the under-reporting of cases, in particular due to the omicron variant, which has considerably increased the notification of positive cases of covid-19 in the city.

“We haven’t had any major dengue fever outbreaks recently, but there may even have been dengue deaths and there wasn’t this perception, a lot of people have the disease and there are few. who have severe cases. People don’t want to go out and expose themselves because of the variants, especially those in risk groups. I don’t think we have a great idea of ​​how serious dengue fever is,” Silvia said.

Officially launched in 2015, the dengue fever vaccine arrived with the aim of controlling the disease and ensuring people’s health. However, the specificity of the groups covered and the non-availability of the immunizing agent in the public health network mean that vaccination is not widely distributed.

According to Silvia, although good, the dengue immunizing agent is impractical. According to her, only people between the ages of 9 and 40 can receive the vaccine. In addition, the person must have had dengue fever at least once. “Three doses are needed and the interval between each is six months. In other words, it takes practically a year and a half to be completely immunized and you still have to insert the person in this context of having already been infected”.

In the opinion of the infectiologist, these factors contribute to the fact that the vaccine is not commented on so much, even in times of greater proliferation of the dengue mosquito. “It is curious that the people who die the most from dengue are not covered. It’s an intramuscular vaccine and it has a very small group, so a lot of things are going against it. We want another vaccine to appear,” Silvia said.

Earlier this year, the Diário production asked the town hall of Uberlândia for data on the cases of the three diseases transmitted by Aedes aegypti in the city. Check it out below:

Confirmed dengue fever cases per year:
– 2020: 1,988
– 2021: 701

Confirmed cases of chigungunya by year:
– 2020: 5
– 2021: 3

Confirmed Zika cases by year:
– 2020: 0
– 2021: 0

The “Udi sem Dengue” application of the Uberlândia town hall was launched in 2019. Through the application, the population can send photos, videos and text or voice messages alerting the teams of the control program of the dengue fever, from the Zoonoses Control Center (CCZ) on possible mosquito breeding sites.

“Udi sem Dengue” also helps agents in the fight against the mosquito, since the application works as a manager, monitoring more than 900 ovitraps (traps that allow mosquito tracking) distributed in the city, as well as swimming pools and reservoirs recorded for the insertion of the puppet fish.

To use the application, it is necessary to download it from your mobile application store. After that, just enter the CPF, personal data and register. A code will be sent to verify registration. In the application the user can find information, requests, suspected cases of dengue fever, zoonoses, news and contact us.

The state health department guides residents in the fight against the mosquito. Eliminating breeding sites is the main way to reduce the incidence of these diseases. Some attitudes are:

• Dumpsters always covered;
• Garden without rubbish or rubble, bottles and buckets upside down;
• Dry and empty the air conditioning, refrigerator and humidifier water tanks;
• Clean the drains and filter the application;
• Do not use small dishes that accumulate water for flower pots;
• Water pot for cleaning the animals with a loofah or a brush;
• Clean gutters and gutters;
• Periodic maintenance of swimming pools and water tanks;
• Aloes and other plants that accumulate water in a covered area.
• Tarps taut, preventing the formation of puddles of water;
• Do not use pet bottles with drips in plants that have openings the mosquito can enter to lay eggs.
