There is no malaria in Mauritius (just ordinary mosquitoes). You might have a look here: recommended vaccinations for Mauritius traveller. Additionally you might want to start a search in our forum for the different keywords. There can always be a recent update or information from the forum members. Also don’t hesitate to contact your local physician first. He knows your health situation better and can recommend the necessary precautions before the flight.
We do highly recommend a separate health insurance that covers the cost of treatment in the private clinics. Please contact your agent.
