One of the most common parasitic diseases in the tropics is malaria, which is transmitted by mosquitoes. It is a very complicated disease for which, to date, no one has found a cure or vaccine. To this day, it is still the leading cause of death from infectious diseases among travellers to Africa, Asia, South America and Central America, among others. A key issue in malaria prevention is the use of antimalarial drugs, which are selected according to the place and length of stay, type of route or amount of travel. The choice of antimalarial drugs must always be consulted with a doctor.
