Malaria is endemic in many tropical and subtropical regions of the world. Over 300 million people worldwide are infected, with 1 million fatalities annually. [62] The known causative agents are the following 5 species of Plasmodium:

  • P falciparum

  • P malariae

  • P ovale

  • P vivax

  • P knowlesi

Malaria is spread mainly through mosquito bites, but cases of transfusion-transmitted malaria have been reported. The risk of spread depends on the prevalence of the disease. For example, in Benin, where malaria is highly endemic, one third of screened blood donors were found to have P falciparum trophozoites, making them capable of transmitting the disease through blood donation.
