Relapses occur because P. vivax and P. ovale have dormant liver stage parasites (“hypnozoites”) that may reactivate. Treatment to reduce the chance of such relapses is available and should follow treatment of the first attack.
What is the difference between relapse and recrudescence in malaria?

What triggers malaria relapse?
The recurrence in patients with malaria can be caused by reinfection from a new mosquito bite, recrudescence, or relapse [5]. Relapse occurs in P. vivax and P. ovale infections through the activation of hypnozoites in the human liver.
Which stage of malaria causes relapse?
What are relapses? Reactivation of P. vivax hypnozoites from the dormant stage of the parasite causes clinical relapses. Hypnozoites are carried silently, with no symptoms, and humans can transport the parasite to new areas or areas where malaria transmission has been interrupted.
