New Update



Between May 16 and May 29, there were 69 confirmed cases of dengue fever (compared to 115 in the previous period). The South of the island is the most severely affected region, accounting for 56% of all cases. Overall, the number of patients visiting the emergency room and being admitted to the hospital has stayed pretty consistent.


 Since the end of April, fewer cases have been reported. Every incident recorded by the surveillance system is assisted by agents of the Department of Fire and Rescue Service and ARS teams, ensuring a high level of mobilization among vector control players for each reported case.

The number of dengue fever cases this year is much lower than last year. There have been 1,420 reported cases thus far, compared to 21,272 in 2021. The total hospitalization cases have decreased to a total of 50 from the previous year's 1,185.

Residents of Réunion should remain vigilant against dengue fever mosquitoes as the southern winter approaches.


What can be done to stop the spread of dengue fever?

Take care of yourself so that you can look after others. Use repellent, mosquito net, etc. It makes no difference if you've already been infected with dengue; various serotypes circulate, and infection with one does not protect you against infection from the other.

Mosquitoes breed in stagnant water, so it's important to get rid of every water-holding object in your immediate proximity (cups, small containers, gutters, tires, etc.). Dengue symptoms include fever, headache, muscle/joint discomfort, nausea, and vomiting. Consult a doctor about these symptoms and send a sample to the lab recommended by your doctor for testing.

If you have dengue fever, continue to avoid mosquito bites and monitor your health from the fourth to the eighth day of your illness to help prevent the disease from spreading. If your situation worsens, you should seek medical help immediately or contact emergency health services.
