In this sequence, we say that the Dengue Committees – which were created and which should be directly supervised by the 32 boroughs of the city – have also entered the system pending government decisions. “There has been a delay in actions and practically nothing has happened in this area. And, on the other hand, the increase in the lack of care in the North area also contributed to outbreaks of the dengue mosquito,” a source said.

Dengue fever cases in the city of São Paulo:
Provisional data up to 05/10/2022 – Sec.Munic. health

Dengue generally has a cyclical behavior, with epidemic periods (lasting 1 to 2 years) and interepidemic periods (lasting 2 to 3 years). The last epidemic year, both in the municipality and in the state of São Paulo and in Brazil, was 2015. In 2019 there was an increase in notifications and confirmed cases, however, with medium transmission in the capital , which in 2020 was not observed, as there was low transmission.

The year 2020 cannot be used as a parameter to compare dengue fever cases in the capital. The social isolation imposed by the Covid-19 pandemic has led to an atypical situation of low movement of people and a sharp drop in the number of cases.

Dengue fever: one more danger

As revealed by Oswaldo Cruz Foundation (FioCruz) in the city of Abadiana, in Goiás, the first case of the dengue strain with the most active characteristics was detected in Brazil. This dengue is native to countries in Asia, the Middle East and Africa, with serious consequences for humans.

Goiás ranks second, behind São Paulo, in dengue cases. Even the capital Goiânia has declared a public health emergency. The Ministry of Health advises that it is monitoring these cases and has been informed of the detection of the new dengue genotype in this state.

In four months, Brazil exceeded the 544,000 cases of dengue fever recorded last year. From January to April, there were 654,800 notifications of the disease. This year, the federal government reports that it has delivered 40 million larvicide tablets for the treatment of water reservoirs/deposits to all states and the Federal District. In addition, more than 3,000 kilos of insecticide were distributed for treatment at strategic points, such as tire shops and dumps.

But, on the other hand, the Ministry of Health does not currently deliver new molecular kits, which are used for the diagnosis of dengue fever, chikungunya and zika. The delivery of these new kits is scheduled for the month of June.

The cases in the State of São Paulo

consulted by DailyZonaNorte, a State Department of Health/SP report having recorded, in 2022, through May 2, 107,400 dengue cases and 77 deaths. In 2021, during the same period, 104,000 dengue cases and 41 deaths were recorded.

And he recalled that the fight against the Aedes aegypti mosquito is a continuous and collective task. The main preventive measures are: leave the water tank tightly closed and clean it regularly; remove objects that collect water from backyards; take care of the garbage, keep the materials to be recycled in a closed bag and in a covered place; eliminate pot dishes or use a small dish that fits better in the pot; drop off used tires at the town hall’s collection points. And it ends: according to the directive of the Unified Health System (SUS), Actions on the ground to fight against the mosquito vector of dengue fever are primarily the responsibility of the municipalities.

In Guarulhos, according to the latest bulletin published by the Municipal Department of Health, the commune recorded 353 cases of dengue fever between January 1 and May 5 this year. The number is almost half of what was recorded during the same period in 2021, when 626 cases were confirmed. But the moment requires everyone’s attention to keep the Aedes aegypti mosquito away from homes.

An important caveat: Self-medication is a health risk, even more so in the case of dengue fever, for which nonsteroidal (or nonsteroidal) anti-inflammatory drugs and acetylsalicylic acid (ASS) derivatives are contraindicated in all cases of disease. . At the first symptom and in doubt, consult a health center immediately.

Mosquito control should be part of everyone’s routine. The collaboration and participation of the population is a fundamental element to reduce the transmission of the disease.
