Periods of intense heat and heavy rain are conducive to the proliferation of mosquitoes. Aedes aegypti. Therefore, the State Department of Health (SES) through the Epidemiological Surveillance Council (DIVE/SC) is alerting the population to redouble their attention and care with their homes, backyards and its working environment, avoiding the accumulation of water.

“With the greatest amount of rain, the supply of breeding sites where the female mosquito can lay her eggs increases. This, combined with the high temperatures, accelerates the development of the mosquito. Another important detail: the eggs laid there are weeks or months can hatch and give birth to thousands of new mosquitoes when they make a contract with rainwater,” warns João Augusto Brancher Fuck, director of DIVE/SC.

O Aedes aegypti transmits dengue fever, zika and chikungunya. The best way to prevent these diseases is to prevent mosquito breeding. And care should start indoors, removing stored water to prevent possible breeding, such as in flower pots, tires, plastic bottles, unused and maintenance-free swimming pools, water tanks and even in small containers, such as bottle caps. . “The control of Aedes aegypti depends on the action of the whole population. These are simple actions which, if carried out once a week, by eliminating or adapting places with stagnant water, contribute to reducing the risk of transmission of these diseases. This care, aligned with the actions of the public authorities, monitoring and controlling the disease, makes the difference”, underlines the director.

Dengue fever
Usually, the first manifestation of dengue is a high fever (39° to 40°C) of sudden onset, which lasts from two to seven days, associated with headaches, weakness, pain in the body, joints and eyes. . Body spots are present in 50% of cases, and can affect the face, trunk, arms and legs. Loss of appetite, nausea and vomiting may also be present.

“People who show symptoms of the disease must seek treatment at a health service. Similarly, the healthcare network must be vigilant in identifying these suspicions, by carrying out the clinical management as indicated in the risk classification and the patient management flowchart. The rapid management of suspected cases makes it possible to avoid the worsening of the condition and even the evolution towards death”, underlines Ivânia Folster, zoonoses manager at DIVE/SC.

Every fortnight a bulletin on the situation of entomological monitoring in Aedes aegypti and the epidemiological situation of dengue, chikungunya and zika virus in the state is disclosed.

Dengue fever is transmitted through the bite of a mosquito. Aedes aegypti infected with the virus. After the bite, symptoms may appear between four and 10 days. Dengue fever is not contagious, meaning it cannot be passed from person to person, nor is it transmitted by consuming food or water.

The virus can also be transmitted from humans to mosquitoes, in which the mosquito Aedes aegypti by biting a person with dengue, they acquire the virus and can transmit it to other people.

Guidelines to prevent the spread of Aedes aegypti:
– avoid using dishes in potted plants. If you use them, add sand to the edge;
– store the bottles with the neck down;
– keep garbage cans covered;
– always leave the water tanks closed, without any openings, especially the water tanks;
– plants such as bromeliads should be avoided because they accumulate water;
– treat the pool water with chlorine and clean it once a week;
– keep the drains closed and unblocked;
– brush the food and water pots of the animals at least once a week;
– remove the water accumulated on the slabs;
– flush the toilet at least once a week in less frequented toilets;
– keep the toilet lid closed;
– avoid the accumulation of debris, as it can become a home for the dengue mosquito;
– denounce the existence of possible hotbeds of Aedes aegypti the municipal health service;
– if you have symptoms of dengue fever, chikungunya or the zika virus, seek medical care for treatment.
