  • Keep the water tank tightly closed;
  • Tie the garbage bags tightly;
  • Place tires in covered locations;
  • Avoid accumulating scrap and debris;
  • Receive health and endemic agents;
  • Clean the house gutters well;
  • Put sand in plant pots;
  • Empty pet bottles, pots and vases.

There are also some individual precautions that can be implemented to reduce the chances of you being bitten by a mosquito. Check it out below:

  1. Protect areas of the body that mosquitoes can bite by wearing pants and long-sleeved shirts;
  2. Use repellents based on DEET (diethylmetatoluamide), IR3535 or icaridin on the parts of the body that are exposed. They can also be applied to clothes;
  3. Use mosquito nets over the bed, screens on doors and windows and, if possible, air conditioning.

Symptoms of the disease

As with any disease, the sooner dengue is identified, the faster and more effective the treatment will be. Keep an eye out for possible symptoms.

If you or someone close to you shows signs that you have dengue fever, look for a health unit.

The main symptoms of dengue are:

  • Headache or pain in the area behind the eyes;
  • High and persistent fever;
  • Diarrhea or severe pain in the stomach;
  • Frequent nausea and vomiting;
  • Low pressure;
  • Spontaneous bleeding;
  • Decrease in urine;
  • Red spots (rash);
  • Muscle and joint pain;
  • Cold extremities (feet and hands);
  • Agitation or drowsiness.


It is worth remembering that there is already a vaccine against dengue in Brazil, but it is still insufficient for the entire population. The federal government has already sent doses to the states and is prioritizing places with a higher incidence of the disease.

The doses are being distributed to 521 cities that are within regions considered endemic for the disease. The priority at this time is to immunize children aged 10 to 14.

This age group has the highest rate of hospitalizations due to dengue, behind only the elderly. Some private laboratories and clinics have also started offering the vaccine. Stay tuned!
