Deforestation And The Sub Saharan Regions Of The African...

Engulfing the Congo and the Sub-Saharan regions of the African peninsula, a new threat has emerged; lying below the mucky surface of a deforested plain, a killer has taken root. At risk is half of the world’s population who reside in the 106 countries and territories that are prone to plasmodium falciparum transmission. Who is this killer? Anopheles gambiae complex, which has devastated the African region acting as a vector for the parasite plasmodium falciparum, more commonly referred to as malaria. Why has a parasite that is responsible for approximately half of all recorded deaths relatively unheard of in Western civilization? The answer lies with the deforestation and non-sustainable practices that plague the African union.†¦show more content†¦Annually, 200 million malaria cases are contracted and of these, 90% occur in Sub-Saharan Africa. Approximately one million people die annually, making plasmodium falciparum the most deadly parasitic disease. Contraction of plasmodium falciparum begins when a female Anopheles mosquito injects sporozoites, an early form of plasmodium falciparum, into the host. This sporozite is then transported to the human liver where it undergoes asexual reproduction producing merozoites. The merozoites invade other liver cells and enter the host’s bloodstream, where they invade erythrocyte. After the infection of the erythrocyte, the merozoite is transformed into a trophozoite, which then begins asexual reproduction near the nucleus to form a schizont in the erythrocytic cell. The schizont then asexually reproduces to produce mononucleated merozoites. When the erythrocytic cell ruptures due to the 3,000-4,000 merozoites produced, symptoms of fever and chills are induced within the host. This life cycle is extremely damaging to children; persons under the age of 5 account for 86% of malaria fatalities. Malaria has other characteristic effects, such as yellowing of the skin/eyes (jaundice), sweating, vomiting, weakness, and nausea. Current mortality rates in Africa are 9.33% per 1000 children, which represent 28.2% of all fatalities for those under five.
