Health authorities recommend that the population:

Continue to protect yourself, even if you have already been sick with dengue before; several dengue serotypes can circulate and infection with one serotype does not protect against attack by another serotype.

– Eliminate and empty stagnant water that may contain mosquito breeding grounds: anything that may contain water all around your home, check the gutters, etc.

– Consult a doctor in the event of symptoms: fever, headache, muscle/joint pain, nausea, vomiting, etc. and take the sample in the medical analysis laboratory prescribed by your doctor to confirm the diagnosis of dengue fever.

If you are sick with dengue fever:

Continue to protect yourself against mosquito bites to avoid transmitting the disease to those around you and monitor your state of health, especially between the 4th and 8th day of illness,

consult your doctor or an emergency service if your state of health deteriorates.
