Malaria, Caused by Mosquitos, Can Cause Death

To sum it all up, malaria is caused by parasite-infected mosquitoes, signs of malaria are basically changes in temperature from colds to fevers, it is diagnosed by extinguishable malaria parasites in the blood and treatment is determined by the severity of the disease, the outcome is usually complete recovery and in some cases, death is the only way out, and preventing malaria is all about preventing mosquitoes Again, malaria is a disastrous disease, one you don’t want to get; one that no one wants to get. Malaria is a disease worth knowing about, because it has killed an immense amount of people.

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. The reasons why Western Cambodia is a big place for drug-resistance are unknown. The falciparith parasite that lies in Cambodia is one of the four types of malaria and is the most deadly. Through a Mosquito, it enters the bloodstream and after 2 weeks of incubating, it multiplies and takes over red blood cells.

What is the disease: Malaria is a mosquito-borne infectious disease to humans and other animals which is caused by parasitic protozoans. You develop it by a female infected mosquito with parasites transmitting its bite through the skin. This can cause severe redness on the area and continuous itching which can cause the bite to inflame. Malaria is quite rare in countries such as the United States, but it is most commonly found in countries such as Southern Asia and Africa. It is said that there is 20 species around the world but there are 4 most common species that cause the disease in humans a few are known as: Plasmodium falciparum, this is the most deadly out of all 4 to humans this lies in the salivary glands of the mosquito and it is transmitted to humans by the females of the Anopheles of the mosquito.

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.

The researchers concluded that vivax malaria is “rapidly evolving” and “important genes” might have been missed that allows the P.vivax to become susceptible to even Duffy negative people (AAAS, 2014). In conclusion, malaria causes the most deaths worldwide out the parasitic diseases known. The life cycle process is a rather complex process. Therefore, it is essential in understanding the concept of how the malarial parasite invades the human host and that P. vivax accounts for majority of the malaria cases. Bibliography

Malaria is a serious, parasitic infection that is spread by the bite of certain mosquitoes. A parasite is an organism that survives by living inside a larger organism, called a host. Malaria is spread in three ways. The most common is by the bite of an infected female Anopheles mosquito. However, malaria can also be spread through a transfusion of infected blood or by sharing a needle with an infected person.

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, 1996). 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.

Furthermore, the malaria parasites also destroy the intracellular proteins present in the red blood cells, mainly the hemoglobin, infecting the red blood cells and causing its rupture. Additionally, the more the red cells are destroyed, the less the hemoglobin will be available, causing anemia. And if actions of treatment don’t be taken, serious complications may rise such as restriction of blood flow to the brain, damage of other vital organs, malaria cerebral and even death. Malaria is a very danger pathogen and its necessary to don’t be neglected once diagnosed.

Those infected with malaria may also suffer from anaemia and its symptoms; fatigue, pale skin, weakness, tiring easily, low blood pressure, heart palpitations, difficulties concentrating, loss of appetite and a cracked or reddened tongue. P. falciparum is the most dangerous form of malaria found in humans, and it has the highest rates of complications and mortality. It can lead to include jaundice, coagulation defects, spleen rupture, anaemia, shock,... ... middle of paper ... ...sion, producing thousands of active haploid forms called sporozoites, which can be injected into another human through a bite. The life cycle of the malaria parasite repeats itself. Malaria is a leading cause of death and disease worldwide, with approximately 300-500 million cases per year reported and 1 million deaths annually.

This was because U.S. troops in other countries were not on the proper medication, contracted the disease, and brought it back to the United States. 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.
