Dengue transmission occurs through the bite of the female Aedes Aegypti mosquito, which causes symptoms such as pain in the joints, body, head, nausea, fever above 39ºC and red spots on the body.

Dengue mosquito bites usually occur in the early morning or late afternoon, especially in the region of the legs, ankles or feet. In addition, its bite is more common during the summer, so it is recommended to use repellents on the body and insecticides in the house, for protection.

Dengue prevention can be done with simple practices that mainly avoid the reproduction of the transmitting mosquito, through the elimination of objects that accumulate stagnant water such as tires, bottles and plants.

It is important that all people who live nearby, in the same neighborhood, have these precautions against dengue, because only in this way is it possible to reduce the chances of dengue transmission. Some of the most important precautions for dengue prevention are:

1. Eliminate stagnant water spots

The mosquito that transmits dengue proliferates in places with standing water, so eliminating water sources is essential care to prevent the mosquito from breeding:

  • Keep flower pots and plant dishes with sand;
  • Store bottles upside down;
  • Always clean the pipes;
  • Do not throw garbage in vacant lots;
  • Always put garbage in closed bags;
  • Keep buckets, water tanks and pools always covered;
  • Leave tires sheltered from rain and water;
  • Eliminate plastic cups, soft drink lids, coconut shells in bags that can be sealed;
  • Punch holes in aluminum cans before being discarded so as not to accumulate water;
  • Wash bird and animal drinking troughs at least once a week;

If a person identifies a vacant lot with accumulated garbage and objects with standing water, it is necessary to notify a competent authority, such as the National He alth Surveillance Agency - Anvisa on the phone 0800 642 9782 or call the city hall.

2. Apply larvicides

In places with many sources of stagnant water such as scrap yards, junkyards or garbage dumps, larvicides are applied, that is, chemicals that eliminate mosquito eggs and larvae. However, this application must always be carried out by trained professionals, being indicated by the municipal he alth departments.

The type of application depends on the amount of mosquito larvae found and generally does not cause any harm to people's he alth. These applications can be:

  • Focal: consists of applying small amounts of larvicides directly to objects with standing water, such as potted plants and tires;
  • Perifocal: is similar to extermination and is based on placing larvicides with a device that releases chemical product droplets, must be done by trained people and with personal protective equipment;
  • Ultralow volume: also known as smoke, which is when a car emits smoke that helps eliminate mosquito larvae, and is performed in cases where there is an outbreak of dengue.

Furthermore, community he alth agents who work at he alth centers often visit neighborhood homes in order to detect and destroy water reservoirs that are accumulating water, helping to reduce dengue transmission outbreaks.

3. Avoid being bitten by the mosquito

As dengue is transmitted by the Aedes aegypti mosquito, it is possible to prevent the disease through measures that avoid the bite of this mosquito, such as:

  • Wear long pants and long-sleeved blouse in times of epidemic;
  • Apply repellent daily to exposed areas of the body, such as face, ears, neck and hands;
  • Have protective screens on all windows and doors in the house;
  • Light a citronella candle at home, as it is insect repellent;
  • Avoid going to places with dengue epidemics.

Before applying any repellent, it is necessary to check if the product is approved by Anvisa and if it contains less than 20% of active ingredients such as DEET, icaridin and IR3535. However, some repellents can be made at home using plants.See options for homemade repellents for children and adults.

4. Get the dengue vaccine

A vaccine that protects the body against dengue is available in Brazil, which is indicated for people up to 45 years of age who have had dengue several times and who live in places with many cases of this disease. In addition, this vaccine is not available through the SUS and is only available in private clinics. See how the dengue vaccine is made.
