Health authorities have reported elevated dengue fever activity in multiple areas in Mauritius, with more than 210 cases reported June 3-July 23. Mauritius island (156 cases) is the most affected, reporting the highest disease activity, followed by Rodrigues Island (57 cases). Health officials have implemented preventative measures such as fumigation in areas that have reported disease activity. Contact tracing has also been implemented and is ongoing. This represents the most complete information available as of July 25.
Context
Dengue fever is considered a year-round threat in Mauritius, with the highest risk occurring February-March. Health authorities identified no confirmed cases of dengue fever in Mauritius in 2022 and 2021, 228 cases in 2020, and 152 cases in 2019.
A dengue fever vaccine is available in some countries. It is only recommended for individuals with a history of dengue infection and in countries with high dengue fever burdens. Dengue fever is transmitted through the bite of an infected mosquito. Symptoms of dengue fever include a sudden onset of fever and at least one of the following: a severe headache, severe pain behind the eyes, muscle and 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.
Advice
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.
