If this kind of infection goes untreated, it usually lasts for 2-3 months with diminishing frequency and intensity of paroxysms. Of patients infected with P vivax, 50% experience a relapse within a few weeks to 5 years after the initial illness. Splenic rupture may be associated with P vivax infection secondary to splenomegaly resulting from RBC sequestration. P vivax infects only immature RBCs, leading to limited parasitemia.
