Malaria is an communicable disease caused by the infection of malaria parasites by the bite of Anopheles mosquitoes or the blood of people with Plasmodium. There are four parasites parasitizing the human body, namely Plasmodium vivax, Plasmodium malariae, Plasmodium falciparum, and Plasmodium ovale. Different Plasmodium species cause P. vivax, P. malaria, P. falciparum and P. ovale, respectively. The disease is mainly characterized by periodic regular seizures, systemic chills, fever, and hyperhidrosis. After a long period of repeated episodes, it can cause anemia and splenomegaly.
On October 27, 2017, the World Health Organization’s International Agency for Research on Cancer (IARC) published an initial review of the list of carcinogens, and malaria (caused by Plasmodium falciparum infection in highly endemic areas) was in the list of category 2A carcinogens.
