Examples
Although P. falciparum traditionally accounts for the majority of deaths, recent evidence suggests that P. vivax malaria is associated with potentially life-threatening conditions about as often as with a diagnosis of P. falciparum infection.
Among those infected, P. falciparum is the most common species identified (~75%) followed by P. vivax (~20%).
Hypnozoites are responsible for long incubation and late relapses in P. vivax infections, although their existence in P. ovale is uncertain.
Treatment with tafenoquine prevents relapses after confirmed P. vivax malaria. citation Severe and complicated malaria are almost always caused by infection with P. falciparum.
Infection with P. vivax, P. ovale or P. malariae usually do not require hospitalization.
P. vivax proportionally is more common outside Africa.
