Understanding Malaria
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 kills more people than any communicable disease except for tuberculosis. It is caused by four species of parasitic protozoa that infect human red blood cells. Four different types of these protozoa are known: protozoa falciparum, protozoa vivax, protozoa ovale, and protozoa malariae. Protozoa falciparum is the most lethal of the four and accounts for the majority of infections. Malaria parasites are not able to survive unless they have both a mosquito and human host, however the disease cannot be hosted by any kind of mosquito, only those of the genus "anopheles".
Malaria is spread when the mosquito picks up the parasites from the blood of an infected human when it feeds. The mosquito will first recieve the malaria parasite from feeding on the blood of a person who may not neccessarily show symptoms of the disease, but has the parasites in their bloodstream. When the mosquito feeds again, these parasites will be passed on to another human being. Symptoms of malaria include fever, shivering, pain in the joints, headache, repeated vomiting, generalized convulsions, and coma. If not treated, the disease, especially that caused by protozoa falciparum, will progress to severe malaria. Severe malaria generally results in death.

...DT has been in use in malaria control programs since the 1940's and has proved generally effective. The most common use of DDT in preventing the spread of malaria is to spray the backs of chairs and walls of a dwelling with the substance to keep out adult mosquitos who enter the dwelling to feed on those who live there. Though DDT treatments are still an effective way to stop the spread of malaria, some mosquitos have become resistant to the compound and therefore more methods of prevention must be utilized.

Rachel Lloyd’s book is really a call to action because her book is saying that child trafficking is real and it’s something that needs to be stopped in it tracks right now because there are still victims and they need to know that their idea of safe is not the real meaning of it by a long shot.
There is little at face value that would alert an educated individual to the severity and the danger of Syphilis – the bacterium which causes syphilis, Treponema pallidum, appears as nothing more than a simple bacterium. The bacterium is spiral in shape, and is classified as Gram Negative (meaning that the bacterium lacks a thick layer of peptidoglycan in its cell wall). Syphilis infects it's victims through a limited number of ways – the most common way, however, is by entrance through chafed, cracked skin and through mucous membranes. Because of this, Syphilis is so effectively transmitted through sexual contact and sexual activity that it is primarily known as a Sexually Transmitted Infection (STI). However, Syphilis does not limit itself to only the aforementioned modes of transportation. The disease is also effectively transmitted through blood transfusions, not to mention the passing of Syphilis from mother to child in the womb during pregnancy (CDC 2007).
Nearly 500 whales beach themselves every year due to an excessive use of sonar. Military passive sonar (sound navigation and ranging) is killing and causing whales to avoid their major feeding and breeding grounds while temporarily deflecting from the high frequency sound coming from this unknown source. This event is raising hell in the political sector. Scientists have found many similarities between all the beached whales that have been in the same area that military sonar was being used. Military sonar is affecting the life of whales and their natural habitat for the worst.
In the world today, we know that whales are majestic creatures with amazing lifestyles that we don’t completely understand. We also know that however large they are, they are in danger because they have been over hunted and over used by human beings. Today through Commercial Whaling, the whales of the oceans have been put at risk and their population continues to decrease. Countries such as Japan, Iceland, and Norway defy the rules set by The International Whaling Commission under the pretense that they’re whaling for scientific reasons, when in reality they are whaling for commercial reasons of profit. Commercial whaling is a problem in countries around the world, most prominent are the Japanese, and other countries are Iceland and Norway. Over time the status of the whale population has declined because of the increase of technology in whale hunting.
Although whale watching is spectacular to watch lets go more in-depth with the affects sonar has on the environment. Sound Navigation and Ranging has a warrant out for whales and has accounted for more than
Malaria is a disease that is in the blood; it comes from the plasmodium parasite. Malaria is carried from a mosquito to person then it spreads from person to person. (Kar,N) There are over a hundred species with malaria parasite that are highly populated in Africa these parasites are called Plasmodium falciparum. (Kar,N) when a parasite gets into a humans system it finds its way in the liver where it creates approximately ten thousand more. (Kar,N) Female mosquitos transmit malaria. (Kar,N) Two weeks in the body parasite move into the blood stream where it starts messing up the red blood cells. (Kar,N) It usually takes 10 days to four weeks after

Thesis Statement: The deadly virus Ebola is killing thousands of innocent people world wide, but there are some simple steps that are being taken to prevent this coming tide of death.
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...
Malaria is a deadly disease that is transmitted to humans via bites from infected female mosquitos carrying malaria parasites. People who develop the disease often become “very sick with high fever, shaking chills, and flu-like symptoms” (CDC). According to National Geographic, "malaria now affects more people than ever before. It's endemic to 106 nations, threatening half the world's population…This year malaria will strike up to a half billion people. At least a million will die, most of them under age five, the vast majority living in Africa,” (National Geographic). The high concentration of malaria-afflicted citizens in Africa can be attributed to the conducive climate for mosquitos, the sheer number of mosquitos, and most importantly, the inability for many countries to sustain enough anti-malarial resources, medical care, and preventative measu...
Though Frankenstein may seem like just another horror story, a closer look at its message indicates a strong presence of feminist themes. Through Victor Frankenstein’s thoughts and actions, one can easily see Shelley’s intention of revealing men’s fears toward strong women in society. While it may have not been able to change the place of women in society, Frankenstein is step toward unveiling the hidden strength of a woman’s voice.
As the mosquito takes the blood from the human during the process it only injects a tiny amount of its saliva into the skin wound, with this the saliva has antihemostatic molecules and anti-inflammatory enzymes within it which slow the body’s natural blood clotting process and produces the itching/stinging pain. P. Vivax, this is the most frequent and widely distributed cause of malaria that reoccurs; it’s also one of the most common kinds of parasites that infect humans. It can cause very violent headaches, high fever, vomiting, excessive sweating & expansion of the spleen. P.Ovale, this causes tertian (recurs every second day) malaria in humans. This species is very closely related to both plasmodium falciparum and P. Vivax.
Malaria is a serious and sometimes fatal disease caused by a Anopheles parasite that commonly infects a certain type of mosquito which targets humans. People who get malaria are typically very sick with high fevers, shaking chills, and flu-like illness, which are very fatal. The global pattern of Malaria is in a spatial pattern as it occurs in more than 100 countries and territories. About half the worlds population is at risk. Malaria is located in a loosely linear pattern across the equatorial belt, meaning it runs along a line and cuts through most continents, such as the continent of Afica, south east Asia, northern part of south America, Middle East and Austrilasia these places are all considered areas where malaria transmission occurs.
Malaria is caused by Plasmodium parasites found in mosquitoes that carry an infectious disease. It is spread from the saliva through a bite of an infected female mosquito. Only female mosquitoes feed on blood, so this is why females are the carriers and spreaders of Malaria. Once you are bitten by an infected female mosquito then it releases the parasite into your blood where it moves to your liver and expands. This causes your liver to burst sending the infection back to your blood stream spreading to other areas of your body.
...allergic to penicillin3. All individuals with a positive laboratory result for Syphilis and the sexual partners of those infected are treated3. Safe sex education, increasing public awareness and partner tracking of the infected individuals are being implemented to reduce the occurrence of Syphilis. A patient with syphilis should be taught to avoid sexual contact until they have finished their antibiotic therapy to prevent transmitting the infection to others 4. Patients should also be taught the importance of notifying all recent previous sexual partners so that they can be tested and be treated if necessary4. It may be embarrassing for infected individual, but the health care provider needs to stress the importance of disclosing the information to their sexual partners. All cases of syphilis cases need to be reported to the public health authorities4.
