Recommendations to protect yourself from mosquito bites and dengue fever

• To protect yourself, including during the 7 days following the onset of symptoms to protect those around you (repellent, mosquito net…) ;

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

• Eliminate and empty stagnant water, which can constitute breeding grounds for mosquitoes :

everything that can contain water at home and all around your home…

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

• If you are sick with dengue fever :

• keep protecting yourself from mosquito bites to avoid transmitting the disease to those around you and monitor your state of health, especially between the 4^th and the 8^th sick day,

• consult your doctor or an emergency service in the event of a deterioration in your state of health.
