Malaria risk in Port Louis

Malaria Prevention Guide for Port Louis, Mauritius

Risk Score: 71/100

Malaria is a serious disease caused by parasites that enter your blood through the bite of an infected Anopheles mosquito. Symptoms include high fever, chills, sweating, headache, nausea, and body aches. Without treatment, it can become life-threatening within hours.

Port Louis presents specific risk factors that travelers should understand. The capital's dense urban environment, combined with its tropical climate, creates pockets where stagnant water collects in construction sites, drains, and water containers near markets and older neighborhoods. The port area sees regular movement of goods and people from malaria-endemic regions in East Africa and Madagascar, increasing the chance that infected mosquitoes arrive on ships or that travelers carry the parasite. Evening and nighttime activity near waterfront areas and poorly drained zones raises exposure risk significantly.

Here are five practical steps to protect yourself.

First, use insect repellent containing DEET at 30 percent concentration or picaridin on all exposed skin, especially from dusk through dawn when Anopheles mosquitoes are most active.

Second, wear long sleeves and long pants during evening hours. Light-colored clothing is less attractive to mosquitoes than dark colors.

Third, sleep under an insecticide-treated bed net if your accommodation lacks air conditioning or screened windows. Check that the net has no holes and is tucked under the mattress.

Fourth, stay in accommodations with intact window screens and working air conditioning. Request that your hotel room be treated with a pyrethroid spray if you notice mosquitoes indoors.

Fifth, consult your doctor at least four weeks before travel about prophylactic antimalarial medication. Doxycycline and atovaquone-proguanil are commonly prescribed options. Take the full course as directed, including after you leave the area.

Seek immediate medical attention if you develop fever within three months of travel to Port Louis. Inform your doctor about your travel history so they can test for malaria promptly.
