Such as Sheet showed, the Ministry of Health is out of stock of an insecticide used to combat disease-transmitting mosquitoes and has been trying to buy the input since the end of 2021, which has jeopardized the supply of states and municipalities.
The product is used in the nebulization process, the so-called fogging, to control the aedes aegyptiwhich transmits dengue, zika virus, chikungunya and yellow fever.
Júlio Croda, president of the Brazilian Society of Tropical Medicine, explains that it is difficult to establish that the upward trend in numbers will continue, despite favorable weather conditions.
“We are having a rainy and hot summer. Generally, when the rain stops and it starts to warm up, there is an increase in cases. In Brazil, the peak of dengue is generally from April. We had a year of 2022 with many cases , very similar to the worst of the last four years, which was 2019. Generally, when one year has many cases, the next will not be the same even with favorable weather conditions. This is the dengue pattern in Brazil. There are not two very bad years “, he states.
“In the case of chikungunya, in 2022, there was no major outbreak of the disease, despite having been the year with the most cases, compared to the last four, according to the epidemiological bulletin of the Ministry of Health.”
For him, it is up to the government to guarantee a better basic sanitation structure throughout the country. The population needs to check and eliminate outbreaks every seven days.
“In terms of public authorities, we have repeated cycles of dengue epidemics because there is a lack of running water on a regular basis, garbage collection. These are structural characteristics that favor the proliferation of the mosquito, because people accumulate garbage, water at home and the mosquito becomes reproduces in these environments”, concludes Croda.
