Dengue : Le nombre de cas poursuit sa baisse, la région Sud reste la plus concernée

The number of cases continues to fall, with the southern region remaining the most affected

From May 16 to 29, 69 cases of dengue were recorded (up from 115 in the previous period). The South remains the most affected region with 56% of cases. The number of emergency room and hospitalizations remains broadly stable.

Since the end of April, the number of cases has been declining. The actors of the vector fight remain strongly mobilized: the ARS teams, supported by the agents of the Departmental Fire and Rescue Service, intervene around all the cases reported by the surveillance device.

The figures for dengue this year remain well below those of the previous year in the same period:

  • 1,420 cases to date compared to 21,272 in 2021
  • 139 emergency room visits to date compared to 2,738 in 2021
  • and 50 hospitalizations to date compared to 1,185 in 2021.

At the beginning of this austral winter, Reunionese are encouraged to take steps to protect themselves from dengue-carrying mosquitoes: remove anything that may contain water in their homes, use repellents, mosquito nets… and immediately consult a doctor at the first symptoms.

Recommendations to protect against mosquito bites and dengue

  • Protect yourself, including for 7 days after the onset of symptoms to protect your surroundings (repellent, mosquito net…)

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

  • Eliminate and drain stagnant water, which can form mosquito nets:

everything that can contain water in your home and all around your home (cups, small containers, gutters, tires,…

  • Consult a doctor at the first symptoms: fever, headache, muscle / joint pain, nausea, vomiting … and perform the medical analysis laboratory test prescribed by your doctor to confirm the diagnosis of dengue.
  • If you are sick with dengue:
  • continue to protect yourself from mosquito bites to prevent the spread of the disease to those around you and monitor your health, especially between the 4th and 8th day of illness,
  • consult your doctor or emergency department if your health deteriorates.
