Health authorities have reported elevated dengue fever activity in multiple areas in Mauritius, with 498 total cases reported Jan. 1-Feb. 5. This is compared to the 265 cases reported in the country in 2023. Disease activity has been reported in 11 of Mauritius' regions, with Port-Louis (317 cases) being the most affected, followed by the North regions (98 cases). Local health officials urge the public to seek immediate medical attention if experiencing any symptoms. This report represents the most complete data available as of Feb. 15.
If you have previously been infected with dengue fever, consult with your physician regarding vaccination. Avoid mosquito bites and remove standing water to reduce the number of biting mosquitoes. Seek medical attention if symptoms develop within two weeks of being in affected areas. Do not use aspirin or ibuprofen products if dengue fever is suspected, as these could exacerbate bleeding tendencies associated with the disease.
Dengue fever is considered a year-round threat in Mauritius, with the highest risk occurring from February-March. Health authorities identified 265 cases of dengue fever in Mauritius in 2023, no confirmed cases in 2022 and 2021, and 228 cases in 2020.
There are two dengue fever vaccines, Dengvaxia and Qdenga. It is only recommended for individuals with a history of dengue infection and in a country with a high dengue fever burden. Dengue fever is transmitted through the bite of an infected mosquito. The risk of infection is often highest in urban and semi-urban areas. Symptoms of dengue fever include a sudden onset of fever and at least one of the following: severe headache, severe pain behind the eyes, muscle and/or joint pain, rash, easy bruising, and/or nose or gum bleeding. Symptoms typically appear 5-7 days after being bitten but can develop up to 10 days after exposure. Dengue fever can progress to a more severe form known as dengue hemorrhagic fever (DHF). DHF can be fatal if it is not recognized and treated promptly.
