The Malaria Parasite Plasmodium and the Epidemiology of the Disease
Abstract
For ages malaria has affected mankind in almost all parts of the world. It has left a deep imprint on people who have been affected with the disease, and even today in countries where epidemics are common, malaria is a constant threat to people's daily lives. Malaria is caused by protozoan parasites of the genus Plasmodium (phylum Apicomplexa), and there are four species in the genus that cause the disease in humans. Their primary hosts and transmission vectors are female mosquitoes of the genus Anopheles; humans act as intermediate hosts. Places near the equator with a warm, subtropical climate are most susceptible to malaria endemics. More than half of the cases of malaria occur in sub-Saharan Africa. It was only recently that developments have been made to research the eradication of the disease on a global scale.
Malaria, Italian for ?bad air?, is an infectious disease which for nearly 4,000 years has terrorized mankind in many parts of the world. It has greatly influenced human populations and human history, and even today, malaria is a leading cause of disease and death in the world with over one million deaths every year (Sherman 91). This means that every 30 seconds, a person dies from malaria. Unfortunately, the general public knows only little about the disease, which is one of the key reasons as to why so many people suffer from malaria. However, since the turn of the 20th century, a great deal of knowledge has been uncovered by microbiologists about this merciless killer.
The biology behind malaria is extremely complex. As opposed to popular belief, malaria is actually a family of four different diseases caused by four different parasi...

By the name of “superspecies” we try to change the world feature and control the nature with science. With science, a lot of technology has been invented to support people demand for products. Without anticipation about the bad consequences, sometime the invention is causing more damaged than it provide in later on. In 1930, DDT that use for killing insect was discovered by Paul Mueller, working for the chemical company Geigy in Switzerland. For this reason, the benefits of using DDT became immediately obvious (65). Years letter, the unbelievable side effect of using DDT was found. While Biologists investigated the decline of eagles and hawks, they discovered the hitherto phenomenon of “biomagnification”, which compounds gather as they are ingested up the food chain (67). DDT phenomenon proves that thinking like science is only to understand the world in separate pieces. It is lack of understanding the rhythms, patterns and cycles of the nature. Therefore, we need to think beyond the science to see the connections between us and nature because in the reality this world is the world of
The pesticide DDT banned in 1987 was a detrimental to the environment leading to it to be banned in 1987. DDT remains in the soils for a long period of time. The chemicals affect the ecology of the soil and water run off causing contamination of livestock and native animals and aquatic species. Studies indicated a range of human health impacts from DDT including cancers, infertility, miscarriage and nervous system impairment. The social and economic impact of DDT use in viticulture was significant.
The history of life on earth could be thought of as a record of living things interacting with their surroundings; for most of history, this has meant that life molds over time by the environment it inhabits; however, very recently, humans have become capable of altering the environment in significant ways (Carson 49). Marine Biologist, Rachel Carson, in her environmental sciences book, The Silent Spring, documents the detrimental effects on the environment by the indiscriminate use of pesticides. Carson argues vigilantly in an attempt to persuade her extremely diverse and expansive global audience, under the impression that chemicals, such as DDT, were safe for their health, that pesticides are in fact detrimental for their health. Through
What kills more than two thousand children a day could potentially spread around the world. All of the most effective drugs used on this disease in the last evades have gradually been rendered useless by its ability to evolve and develop. It is a life-threatening disease caused by parasites that are spread to people through the bites of infected Mosquitos. The most deadly of this disease lies in Cambodia. This deadly and drug-resistant disease is malaria. The story of drug-resistant malaria in Cambodia is significant because people in other countries could be affected and must be aware of the fact that it is becoming immune to the most powerful drugs used to fight it.
Plasmodium Falciparum is the causative parasite of malignant malaria, it is the most deadly strain of the malaria viruses. P. Falciparum is a eukaryotic protozoan parasite that is spread through vector transmission using mosquitoes. The Anopheles mosquito family accounts for the majority of transmission because of their tendency to target humans (WHO, 2014). Malaria accounts for approximately five hundred thousand deaths each year in environments such as sub-Saharan Africa and other temperate areas where the life cycle of the mosquito is longer allowing the parasite to develop properly (WHO, 2014). Malaria usually infects children in these areas but also commonly spreads to travellers to these areas.
For several years, I have had an interest in virology and the spread and characteristics of various infectious diseases. Though it makes sense not to possibly induce a state of panic by informing individuals of illnesses that are not native to the area they live in and that they are not likely to contract, I have always liked to remain informed out of my own curiosity and interest. Thus, I have decided to write about malaria.
Malaria is a common disease in a hot tropical area and it affects about 300 million people worldwide. There are four types of parasites that cause malaria in humans. Among the types of species Plasmodium falciparum is most common in Africa region and it can cause deadly form of disease. The Plasmodium vivax which is the second type of species is not life-threatening form of malaria. Plasmodium ovale also causes malaria. The system malaria affect most is the immune system. Malaria undergoes a complex life cycle, which involves two separate asexual reproductive stages in the vertebrate host which include humans and sexual reproduction as well as multiplication in the insect vector of all human.
Early in history DDT was a very effective chemical that killed many parasites and stopped the mass spread of malaria. But the reward is not worth the damage that it does to the environment, especially in modern day where we have other ways to prevent parasite and diseases from getting to us. "Top of the Food Chain" by T. Coraghessan Boyle, is a story about the absolute absurdity of things that human beings do to their world and to their fellow living beings. Set during a Senate hearing by a chemical company executive on the defensive about the effects of DDT in Borneo. Basically, poison was used to get rid of mosquitoes. Didn't work. So they brought in geckos, that died from the poison. Cats ate dead geckos, and cats died. This brought on rat infestation. So they brought in more cats and cycle started over again. He is arguing that humans are wrong for destroying their planet with pesticides and other harmful things; this satirical piece effectively supports his argument.
Civilization began with agriculture, and agriculture continues to be an integral part of our lives. Civilization brought knowledge, knowledge brought technology, and technology brought chemicals and pesticides to “improve” our world. “The Obligation to Endure” is an excerpt from Rachel Carson’s “Silent Spring,” a passionate and masterful work on the results of civilization’s efforts to control pests and insects. These effects include destruction of the environment, alteration of gene structures in plants and animals, water contamination, and an upset of nature’s delicate balance. This article is an impassioned plea to the world to understand the threat and demand the information necessary to make an informed consent on use of these deadly substances.
Malaria is a disease that is caused by parasites. It is transferred from one person to another by the infected female Anopheles mosquito. Malaria has been a serious health problem nowadays. WHO has provided the information that approximately 660,000 people died from malaria globally during 2010. Also, after estimating, there are 219 million cases of malaria infection in 2010 worldwide. In sub-Saharan Africa, being one the country that has the high rate of HIV, AIDS, malaria, and tuberculosis, had 90% of the people that...

Malaria in humans is caused by four species of protozoa, sophisticated one-celled organisms, that can infect red blood cells. These four species are called Plasmodium falciparum, plasmodium vivax, plasmodium malariae, and plasmodium ovale. The worst cases are caused by the Plasmodium falciparum species, which is also the species with the most resistance to drugs. To contract malaria, a mosquito, but not just any mosquito must bite a human. The only type of mosquito that can infect humans with the malaria virus is the Anopheles mosquito. While there are...
