Many factors explain the 189% increase in dengue cases across the country compared to January and October last year.
This is the assessment of the researcher and head of the Laboratory of Molecular Biology of Insects at the Instituto Oswaldo Cruz Rafaela Vieira Bruno.
From the beginning of the year until now, 1.3 million notifications of the disease were registered throughout the national territory.
In an interview with CNN Radio she explained that the ideal is to compare the numbers with 2019 – as there may have been underreporting during the pandemic years – and that there is a significant increase in dengue even so.
“We can attribute this increase to the high temperature, the mosquito Aedes aegypti likes high temperatures, he develops well at 28 to 30 degrees, and after the drought comes the rain, with the perfect combination for him.”
The Midwest of the country has the highest incidence of cases, with more than 2 thousand notifications – and this, according to the specialist, is related to the climate.
“People tend to accumulate water in some places when there is no rain and this becomes a breeding ground, in the region there are high temperatures with little rainfall,” he said.
She explains that if it is necessary to accumulate water, the container must be covered with a screen so that the female mosquito does not lay eggs.
Mosquito control involves, for Rafaela, the “integrated action of several agents.”
“Those who will guide residents and check possible breeding sites, in addition to public policies for garbage collection, since a bottle cap can be an environment for the mosquito.”
According to the biologist, “the joint action of the government, with surveillance agents and informing the population to check their own homes” are part of the solution.
Even so, the researcher believes that it is not feasible to completely eliminate the mosquito, and we must learn to live with it and take these measures to reduce its population.
