Inmalaria has led to nearly deaths, mostly among African children The World Health Organization, Malaria is caused by a parasite called Plasmodium, which is transmitted through the bite of infected mosquitoes.
The parasites causing malaria are highly specific, with man as the only host and mosquitoes as the only vector. Every year, , people are affected by malaria, and while less than one percent of these people die, there are still an estimated 1, deaths per year. While Malaria was one of the first infectious diseases to be treated successfully with a drug, scientist are still looking for a cure or at least a vaccination today Cann, Though many people are aware that malaria is a disease, they are unaware that it is life threatening, kills over a million people each year, and is a very elusive Roll back malaria essay for antimalarial drugs Treatment of Malaria, Plasmodium falciparum, Plasmodium vivax, Plasmodium ovale, and Plasmodium malariae.
Not only is the disease specific, but the parasites are too, with only 60 of species of female Anopheles mosquitoes as vectors. With the exception of Plasmodia Malariae which may affect other primates, all parasites of malaria have only one host, Homo sapiens.
Because some mosquitoes contain substances toxic to Plasmodium in their cells, not all species of mosquitoes are vectors of Plasmodium.
Although very specific, malaria still causes disruption of over three hundred million people worldwide each year Cann, The life cycle of the parasite causing malaria exists between two organisms, humans and the Anopheles mosquito.
When a female mosquito bites a human, she injects an anticoagulant saliva which keeps the human bleeding and ensures an even flowing meal for her.
When the vector injects her saliva into the human, it also injects ten percent of her sporozoite load. Once in the bloodstream, the Plasmodium travel to the liver and reproduce by asexual reproduction.
These liver cells then burst releasing the parasites back into the bloodstream where they then enter red blood cells. Here, the Plasmodium feed on hemoglobin and reproduce again by asexual reproduction. Afterwards, the red blood cells burst and release the parasites. Some of the parasites released from red blood cells may be able to replicate by sexual reproduction.
When the host has been bitten by a mosquito again, infected blood inters the mosquito. Here, sexual forms of the parasite develop in the stomach of the Anopheles mosquito completing the parasites life cycle Herman, People infected malaria have several symptoms including fever, chills, headaches, weakness, and an enlarged spleen Herman, The amount of time for symptoms to appear differs depending on the form of the parasite.
Those infected with Plasmodium falciparum experience symptoms after about twenty-four hours, those infected with Plasmodium vivax and Plasmodium ovale produce symptoms after a forty-eight hour interval, and after seventy-two hours Plasmodium malariae begin causing fever and chills Cann, Most malaria cases seem to cluster in the tropical climate areas extending into the subtropics, and malaria is especially endemic in Africa.
In eighty percent of all reported cases were in Africa, while the remainder of most cases came from nine countries: Globally, the disease circulates in almost one hundred countries causing up to 1, deaths annually Cann, Because there is no definite cure for malaria, scientists are trying their hardest to contain the parasite to where it now exists.
The range of a vector from a suitable habitat is fortunately limited to a maximum of two miles Cann, If this were the only factor, scientist would have no problem containing the disease. Humans migrate, however, and over time the disease has slowly spread throughout the tropics.
Major problems also exist when ignorant tourists to Africa transfer the parasite to non malarious areas Graham, Biologists are also using control measures, such as spraying DDT to kill mosquitoes, draining stagnant water, and using the widespread use of nets to contain the mosquito itself Herman, Although limiting the spread of malaria is not easy, finding a cure has presented several problems in recent years.
One main reason finding a cure for malaria is so hard is that different strains in different parts of the world require different drugs, all of which soon lose their effectiveness as the parasite evolves resistance to them Limited Imagination, Roll Back Malaria - Malaria is an important public health disease endemic in over a hundred countries globally.
About 90% of malaria deaths occur in Africa with a child dying every forty five seconds. Malaria accounts for 16% of child deaths in the Africa (Remme, Binka & Nabarro ) and 7% of deaths in children worldwide (WHO ).
The Roll Back Malaria Partnership (RBM), a collaboration between WHO, UNICEF, UNDP, and the World Bank to develop a global, coordinated anti-malaria effort, is now facing an additional obstacle to its goal of ending the malaria epidemic: climate change.
