The tropical zone is the endemic home for all malarial parasites. Plasmodium vivax and Plasmodium falciparum are the species that are prevalent commonly in India. Plasmodium malariae is a parasite of both the tropical and subtropical zones, especially West and East Africa, Guiana and parts of India, but its presence in various zones tends to be patchy. In Karnataka state, its prevalence is rare.
