Down With Mosquitoes and Malaria Malaria has for a long time been among the leading killer diseases in the world. At thesame time there have been noticeable efforts to try and prevent prevalence of malaria. Malaria is more prevalent among young children and expectant mothers but it is important to note that other people too outside theses brackets can contract malaria. Malaria is transmitted by the female anopheles mosquito and therefore one of the best measures to stop malaria prevalence is getting rid of mosquitos. Mosquitos dwell and breed mainly in marshy areas and areas with litter. However, these areas mainly act as mosquitos’ breeding site and therefore people living in around such areas have been found to be the most affected by malaria cases. Several methods such as use of spraying insecticides and depositing pesticide chemicals in water bodies have been used in the past. However, since these methods are not environmental friendly the need to develop other methods of fighting malaria is imminent. In the modern day there has been some advancements such as use of surfactants among other chemical methods.
Surfactants are mainly used in water catchment areas to prevent mosquito breeding. Surfactants comprise of elements that are both soluble and insoluble in water hence the ability to diffuse in water. Furthermore, surfactants adsorb between air and water molecules or molecules of two mixed liquids such as water and oil. This aspect of adsorption forms the basis of using surfactants to prevent mosquito breeding due to the ability to form emulsifications. Surfactants reduce the surface tension of between liquids and or between a liquid and a solid. As a result they can be used in mosquito breeding areas since reduced surface tension makes the mosquitos to drown. Additionally surfactants are organic therefore they do not cause environmental pollution and can hence be considered an efficient method of preventing mosquito breeding. However, use of surfactants in large quantities may have negative environmental effects hence their use is relatively restricted. Some common examples of surfactants are detergents and medicinal lotions.
In addition, researchers have come up with a way of suing heparin to fight malaria. This process involves reducing activity of PfEMP1,which facilitates binding of uninfected RBCs by infected RBCs, by using heparin since it engulfs the infected cells hence preventing the binding.. When red blood cells (RBCs) are infected by malaria parasites they cling to the walls of blood vessels allowing these parasites to multiply and also bind other RBCs thereby forming clumps (Eley 2013). Another advantage of using heparin is that it is cheaply available. However, studies are still being advanced in a bid to perfect use of heparin and even to incorporate it to malaria medication.
Use of DDT treated net has also been adopted in many parts of the world especially the sub Saharan Africa. WHO has been on the fore front to advocate for use of treated nets in a bid to reduce malaria prevalence. Research shows that use of DDT treated nets is the most effective way of reducing malaria cases. This research had sought to compare effectiveness of DDT with other chemicals such as dieldrin and alphacypermethrin. Although on aggregate dieldrin showed more effectiveness in offering protection against malaria, it was found that its effectiveness was short lived due the probability of a quick insecticide build up (Grieco, Achee, Chareonviriyaphap, Suwonkerd, Chauhan, Sardelis, and Roberts 2007). This implies that use of DDT treated nets is highly effective in fighting malaria.
In conclusion, the fight against malaria has intensified and with the ongoing attempts to develop new methods of fighting malaria there is hope that malaria cases will significantly decline. For instance advancements of surfactants and heparin have marked a huge step in combating malaria. Although use of DDT has been in existence over the past years, it is still a useful technique of reducing malaria cases. Therefore, it is in order to conclude that a bright future lay ahead in terms of significantly low cases of malaria.

Malaria

...? Malaria of Introduction Malaria is a parasitic disease, common in the tropic and the subtropics and is characterized by shaking chills, high fever, flu-like symptoms, and anemia. The malarial parasite is transmitted via the bite of an infected female Anopheles mosquito. Once infection occurs, the sporozoite parasites are transported in the victim’s bloodstream to the liver where they mature into merozoites, which re-enter the bloodstream and infect the red blood cells (Shah, 2010). After multiplying in the cells, the parasites break out after 48 to 72 hours. For the female Anopheles mosquito to live and reproduce it must first consume blood meals, which provides the link between human beings and the mosquito genus’s life cycle... . There...

...Sur Supervisor Malaria Malaria has been a major cause of global morbidity and mortality and it spreads mostly during rainy season. Humans get affected due to anopheline mosquitos. The gut of mosquito is the place where malaria protozoa develop. When mosquito sucks blood from the human body, the protozoa enters human body. Due to the process of blood circulation, the parasite reaches to the liver of the person where it multiplies. It takes usually 9-16 days before it penetrates red blood cells causing them to breakdown. The paper attempts to explore the type of microbes that cause malaria; symptoms of...

Malaria

...OF MALARIA Malaria is a disease caused by the one of the four protozoan species of the genus Plasmodium. The four species are Plasmodium falciparum, P.ovale, P. malariae and P. vivax. It is a fatal disease that is caused by the parasite which infects the mosquito first. The mosquito then bites the human and transmits the parasites in the human blood which account for the onset of the symptoms (Cdc.gov, 2010). The lifecycle of this protozoan parasite is divided into two stages, one in mosquito and one in human. The cycle starts when the mosquito bites an infected person. The immature shizonticides (protozoal cells)...

Malaria

...Malaria Broadly speaking, malaria is one of the most pervasive diseases affecting world cultures. The disease occurs as direct result of mosquito infection. Specifically, the disease occurs in humans as they are affected by eukaryotic protists from the Plasmodium genus (Packard 2007). While malaria occurs through the world, its most prevalent areas of occurrence emerge in sub-tropical regions, particularly in the Americans, sub-Saharan Africa, and Asia. The predominance of occurrences in these areas is due to the manifestation of swampland and high mosquito populations that carry and spread the disease. There are many notable symptoms of...

MALARIA

...An Analysis on Malaria History of Malaria Malaria in a disease that is caused by four parasitic Protozoans species belonging to the genus Plasmodium. The disease is classified as vector-borne due to its transmission in vertebrates through bites from infected mosquitoes. The name Malaria was coined from the Medieval Italian ‘mala aria’ which translates to bad air. The name is due to the then belief that the disease was caused by bad smelling air. Researchers believe the disease has existed since the prehistoric times, infecting early primates. However, the first recorded symptoms of the disease were in 2700 BC in China written down in early Chinese medical texts. The disease was first effectively managed from the early 17th Century... ...

...chimpanzees is named as, P. reichenowi. This parasite is consisting of more genetic variability in comparison to those species which target humans. Generically, the older parasites demands more time to evolve variants; hence the diversification form of humans is far less as compared to the chimpanzees. After considering the detailed research on genomes, Stephen Rick found that the human malaria parasites are actually nested inside the parasites of chimpanzees. Meanwhile, the genetic data states P. falciparum as a mutated form of P. reichenowi. There are no such examples found either, which can relate the human malaria originated from a bird or a chicken other than chimpanzees. Stephen Rich’s theory also...
