Malaria (Plasmodium falciparum) in sub-Saharan Africa
Introduction
Malaria is an infectious disease caused by the parasitic protozoan Plasmodium, which can only be transferred by the female Anopheles mosquito. Malaria is spread when the mosquito bites into a person who is already infected. The parasites from the blood uptake reproduce in the mosquito and mix with the saliva so that the next time the mosquito bites another person, parasites are transferred.[1]
There are four parasitic protozoans which cause malaria: Plasmodium falciparum, Plasmodium malariae, Plasmodium ovale, and Plasmodium vivax. Of these parasites, Plasmodium falciparum is the most dangerous and can cause coma or death.[2] Symptoms include fever, chills, vomiting, and nausea and they don’t appear until 10-15 days after the initial mosquito bite.[3]
Malaria kills about 1 million victims per year worldwide, 80% of which are from sub-Saharan Africa. 50,000 deaths occur in Zambia alone. 1 in every 5 children in Africa die from malaria, and costs Africa approximately $12 billion per year in lost wages due to debilitating effects of the disease.[4][5] Although malaria is preventable and curable, misuse of antimalarial drugs over the past century led to parasitic resistance to these malaria medications.[6]
