This year, unlike the four previous years, Reunion has not experienced an epidemic wave with many outbreaks settled on the territory. However, the circulation of the disease was maintained throughout the year, confirming the lasting installation of the disease on the island and its risks of re-emergence.

Finally, at the start of the southern winter, Reunionese are encouraged to maintain actions to protect themselves from mosquito vectors of dengue fever: remove anything that may contain water at home, use repellents, mosquito nets… and consult a doctor immediately at the first symptoms.

Recommendations to protect yourself from mosquito bites and dengue fever
Health authorities recommend that the population:
– Protect yourself against mosquito bites, including during the 7 days following the onset of symptoms to protect those around you > see the Recommendations against Dengue fever section. 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.

The use of bed or cradle/stroller mosquito nets constitutes an effective barrier to protect oneself from mosquito bites, vectors of dengue fever. It is particularly recommended for people forced to be bedridden during the day and newborn babies. Mosquito nets can also be placed on windows and doors for better protection inside homes.
