Optimal mosquito protection 24/7 (during the day against dengue, Zika, Chikungunya and other arboviroses, in the evening and at night against malaria). If you have a fever, take Paracetamol products and make sure you drink enough fluids. Do not take medications containing acetylsalicylic acid (e.g., Aspirin®), as they may increase the risk of bleeding. During and after a stay in a malaria endemic area, malaria should also be considered in case of fever and should always be ruled out by a blood test.
