All malaria infections are serious illnesses and must be treated as a medical emergency. In offering guidance on the choice of antimalarial drugs, the main concern is to provide protection against Plasmodium falciparum malaria, the most dangerous and often fatal form of the illness.
Regardless of the medication which has been taken, it is of utmost importance for travellers and their physician to consider fever and flu-like symptoms appearing 7 days up to several months after leaving a malarious area as a malaria breakthrough. Early diagnosis is essential for successful treatment.
In addition to the suggested antimalarial medication, use a mosquito bed net and effective repellents to avoid the bite of the nocturnal
Anopheles mosquito.
