Answer

Worldwide, an estimated 300-500 million cases occurring annually. [7] It is most prevalent in rural tropical areas below elevations of 1000 m (3282 ft) but is not limited to these climates. P falciparum is found mostly in the tropics and accounts for about 50% of cases and 95% of malarial deaths worldwide. P vivax is distributed more widely than P falciparum, but it causes less morbidity and mortality; however, both P vivax and P ovale can establish a hypnozoite phase in the liver, resulting in latent infection.
