With the arrival of the Amazon winter – a period of heavy rains in the region – the health agencies of the Amazonas government have warned of an increase in the number of cases of diseases caused by the Aedes aegypti mosquito, such as dengue fever. In order to avoid an increase in cases of the disease during this period, the health authorities reiterate that controlling the spread of mosquitoes remains the most effective way to prevent the disease that can lead to death.

Even without hospitalization, registered with the Fundação de Medicina Tropical Dr. Heitor Vieira Dourado (FMT-HVD), a unit associated with the State Department of Health (SES-AM), at the beginning of November, the unit’s infection specialist, Antonio Magella, warned of a possible increase in the number of dengue cases in the coming days.

“The onset of the rainy season brings us a series of concerns about respiratory, viral and bacterial transmitted diseases as well as dengue fever, because our winter is characterized by a larger system of rain, and this causes the presence of mosquito breeding sites, which are already fully adapted to the urban environment,” he explained.

Most cases of dengue fever, according to an infection specialist, are not serious or require medical admission to the hospital. However, the disease must be diagnosed early to avoid progressing to a serious condition.

“There is a critical period for the disease, between the third and sixth day. Patients in this period and those who show signs of danger are the ones who deserve to be hospitalized, so that the treatment can be more robust and more effective,” Magella said.


In addition to the preventive campaigns carried out by SES-AM in order to release the prevalence of buildings and the risks to the population, the authorities are highlighting the importance of the population by taking action to disrupt any purported reproduction of the Aedes Aegypti mosquito.

“This is the main measure to eliminate mosquito breeding sites, because this is where infected mosquitoes will come from that will bite people and transmit disease. And we are playing with a probabilistic situation: the more cases there are, the higher the likelihood of serious cases, and therefore the risk of death,” he emphasized. Antonio Magella.

And the infection specialist warned of measures that could combat the breeding of mosquitoes that transmit the virus. Avoiding the accumulation of water in large or small containers is the main combative measure.

“This mosquito has already acquired evolutionary and biological intelligence in the sense of knowing that that container, no matter how dry, will contain water at any moment. The real enemy is Aedes aegypti, and our best weapon to combat it is to destroy their breeding sites, avoiding any situation, any container, from the smallest To the largest, water can accumulate, whether it is preserved, whether it is rainwater and he concluded: “The important thing is to identify and neutralize these breeding sites.”
