Travellers who develop symptoms of malaria during or after travel should seek medical assessment as soon as possible, as early diagnosis and treatment is essential.

Treatment is guided by the species of Plasmodium causing the infection, the geographical area in which the infection was acquired (and local patterns of drug resistance) and how sick the patient is. Pregnant and breastfeeding women and children require special consideration.

Patients with uncomplicated malaria can be treated with oral medication, however more severe disease requires intravenous medication.

Infections with P. vivax and P. ovale can relapse as the hypnozoite form of the parasite can remain dormant in the liver, and they therefore require additional treatment.
