Consequences for the traveler
Optimal mosquito protection measures 24/7: during the day against dengue, chikungunya, Zika and other viruses, at dusk and at night against malaria. If you should have a fever: take medication containing the ingredient paracetamol and make sure you drink enough fluids. Do not take any medication containing the ingredient acetylsalicylic acid (e.g. Aspirin®), as this may increase the risk of bleeding in the event of a dengue infection (see also factsheet dengue). If you have visited a malaria area and have a fever >37.5 °C, you should always exclude malaria by taking a blood smear on the spot. Visit a medical facility for this (see also factsheet malaria).
