There have been very rainy and very hot days in Brazil in recent months. It is the perfect climate for the reproduction of Aedes aegypt. In stagnant stagnant water somewhere in the corner, nesting sites increased across the country and the disease broke out.

From the beginning of January to April 30, there were more than 654,000 probable cases of dengue fever. That is much more than the full number recorded last year.

Experts are also concerned about the spread of the disease. The situation is worse in the Midwest today, which usually suffers more from the disease and its growth was 272% compared to the same period in 2021.

Then comes the southern region, where incidence has always been lower, but now it records a 263 percent increase in cases.

Infectious scientist Celso Granato says climate change could affect this.

“Dengue was a highly concentrated disease in the Northeast and Midwest, in places where temperatures were more stable. Over the past 20 years, it has reached more and more areas in the Southeast and South. This is related to heating and rain,” Granato explains.

Fiocruz researcher Ademir Martins says the growth is not surprising. He believes that a under-reporting of cases in recent years due to the focus on the coronavirus.

“There’s a problem that people haven’t gone to get help, and also that help is very overloaded and gazes are focused on the Covid problem,” he says.

Virologist José Eduardo Levi says the authorities were negligent.

“When you have limited health resources, like in Brazil and many other countries, a lot was directed at fighting Covidia and you couldn’t fight mosquitoes systematically, as you should do all year round. “Levi says.

Experts also identify the living conditions of the population as one of the reasons for the spread of dengue fever. Mosquitoes are finding more and more space in cities where housing is unstable and public services are poor.

“We’ve left a lot to be desired about waste collection and sanitation infrastructure so people don’t have to collect water,” Ademir Martins says.

“Brazil managed to exterminate Aedes aegypt, but due to the situation in our cities, urbanization, large amounts of debris, stagnant water, etc., this fight against mosquitoes is somehow insane,” Levi says.

Now it gets out of the way of what becomes a breeding ground.

“If everyone takes care of their backyard, because even these mosquitoes don’t fly far, then at least in the immediate vicinity you avoid incidents,” Levi emphasizes.

This year, 214 people died of dengue fever. It is important to be aware of the most serious symptoms so that you can seek help at the right time.

“A person needs to be able to identify a serious form of the disease that is basically stomach pain, not diarrhea, really stomach pain, vomiting and a lot of nausea. This type of alarm forces a person to leave their home and seek first aid, ”explains Celso Granato.
