Essay on malaria

Malaria is a disease characterized by fever and flu like illness that according to the CDC “if not treated can lead to jaundice, kidney failure, seizures, mental confusion, coma, and death” (CDC p.2. There are four types of malaria: Plasmodium falciparum, P. vivax, P. ovale, and P. malariae with the most common type being plasmodium falciparum. (CDC p.1) ).. This disease can only be transmitted by an interaction of blood as the parasite lives in the red blood cells of the infected host individual. This can be due to blood transfusions, sharing of syringes or by its common vector, the Anopheles mosquito.Because of its vector being a mosquito malaria is common in areas with warm temperatures and causes the most damage in poor developing

Malaria is a very contagious parasite transmitted through mosquitoes to humans. Those at risk are individuals living in areas conducive to the breeding of mosquitoes, especially those that allow the mosquitoes to complete their growth cycle. Everyone is at risk

Malaria has been in existence for thousands of years. Many historical records show that it has affected human civilization greatly by plaguing and causing mass death. The earliest record can be traced back to 2700 BC in China (Cox, 2002). It has been long associated with swamps and insects for hundreds of years but often believed to be the air from swamps causing the plague. The term malaria rooted from two Italian words ‘mala’ and ‘aria’ which literally means bad air. Humanity did not know the true nature of the long thought disease until 1894 when a Scottish physician, Sir Ronald Ross, discovered that it was actually the parasite in mosquito that is causing the malaria.

Malaria has been a major life-threatening disease for thousands of years, and continues to threaten millions of lives around the world. It infects approximately 219 million people each year, mostly poor women and children. What is striking about malaria is the fact that it has the worse effect on those with the least ability to fight the disease. The Republic of Cuba believes that malaria prevention, treatment, and research efforts must be accelerated to eliminate the burden of this disease across Africa, Asia, the Americas, and any country or territory at risk of malaria transmissions.

In the article” When mosquitoes were killers in America” by Lauren Tarshis, there is evidence that discussed how mosquitoes were far more than a nuisance. The article talked about the symptoms of having malaria. Tarshis said,”Those who become sick get high fevers, bone - rattling chills, and painful muscle aches.” It must have been very painful for people in the olden days who had malaria. The current generation is very lucky because there are medicines that reduce pain. Malaria is a deadly disease caused by mosquitoes sucking blood and transferring the blood to another human's body. Tarshis talked about how many people die in a year due to mosquitoes. The article says” In this way, bite by itchy bite, 212 million people are infected with malaria

Malaria, on the other hand, was far off more deadly then Yellow fever for it consisted of parasites (Malaria). An engineer once quoted “If we could control malaria, I would be less anxious about other diseases. If we cannot control malaria, our mortality is going to very heavy” (American Canal Construction). Consequently, these infections developed in mosquito salivary glands as well and reproduce in the liver (Malaria). Above all, this incubation period could last for months to a year at a time (Malaria). When the parasites leave the liver they reenter the bloodstream where they are able to infect red blood cells to reproduce once again until the cell bursts (Malaria). As a result, it caused anemia and jaundice from the lack of blood cells (Malaria). Other symptoms include seizures, confusion, coma and death (Malaria).

It is caused by a parasite that infects certain mosquitos that feed on humans. People infected with malaria usually suffer from high fevers, shaking chills, achy muscles, headaches, tiredness, and flu-like illness. It may also cause jaundice and anemia. The malaria parasite is found in the red blood cells of a person which means it can be transmitted through blood transfusions, organ transplants, or the shared use of needles syringes contaminated with blood. Malaria is not contagious; it cannot be transmitted from one person to another. Some parasites can remain dormant in the infected person’s body for up to four years after they are bitten. When the parasite comes out of hibernation and begins to invade the red blood cells, the person will become sick.

Mosquitoes pass malaria to humans through their salivary glands. Once the parasites have entered the blood stream, they go to the liver. In the liver they mature and undergo reproduction, forming merozoites. These merozoites enter the blood stream and inject themselves into red blood cells. Once inside the blood cells, they reproduce rapidly and within forty-eight to seventy-two hours, the blood cell bursts, releasing hemoglobin into the blood stream. It is the destruction of these blood cells and the hemoglobin released into the blood stream that actually causes most of the symptoms.

According to the book, the doctor and his crew of medical professionals learned information about malaria at a lake called Zancudo Cocha, which means “Lake of the Malaria Mosquito”. The word “Malaria” actually can be traced back to Italian roots named mal aria, or bad air. It is caused by the anopheles mosquito, which often had a needle that is infested by parasites. When the anopheles mosquito hits a blood vessel and began extracting blood from the target, the parasites traveled through the bloodstream, which is a part of the cardiovascular system, and found a home at the liver. They would then multiplied and return to the bloodstream to destroy red blood cells, causing fever and chills. Even though there is no effective protection against bug bites, the most effective treatment for most forms of malaria would a synthetic pill called chloroquine.

Malaria is a serious and sometimes fatal disease caused by a parasite that commonly infects a certain type of mosquito which feeds on humans. People who get malaria are typically very sick with high fevers, shaking chills, and flu-like illness.. In 2015 an estimated 212 million cases of malaria occurred worldwide and 429,000 people died, mostly children in the African Region. Although malaria can be a deadly disease, illness and death from malaria can usually be prevented. In Malawi, malaria is very common because

The symptoms vary because patients are diagnosed with having either uncomplicated or severe malaria. This is due to the fact that different kinds of malaria range in severity. For instance, ,P. falciparum and P. knowlesi infections can cause rapidly progressive severe illness and lead to death death while the other species, P. malariae, P. vivax, or P. ovale are less likely to cause such severe manifestations. Furthermore, P. vivax and P. ovale infections also require treatment for the hypnozoite forms that remain dormant in the liver and can cause a relapsing infection. Finally, P. falciparum and P. vivax species have varying drug resistance patterns in different geographic regions. For P. falciparum and P. knowlesi infections, the urgent initiation of appropriate therapy is especially

Malaria is a parasite that attacks the red blood cells in the body, some effects of Malaria are chills, headache, muscle aches, tiredness, nausea, vomiting, and diarrhea.

Annually, 200 million malaria cases are contracted and of these, 90% occur in Sub-Saharan Africa. Approximately one million people die annually, making plasmodium falciparum the most deadly parasitic disease. Contraction of plasmodium falciparum begins when a female Anopheles mosquito injects sporozoites, an early form of plasmodium falciparum, into the host. This sporozite is then transported to the human liver where it undergoes asexual reproduction producing merozoites. The merozoites invade other liver cells and enter the host’s bloodstream, where they invade erythrocyte. After the infection of the erythrocyte, the merozoite is transformed into a trophozoite, which then begins asexual reproduction near the nucleus to form a schizont in the erythrocytic cell. The schizont then asexually reproduces to produce mononucleated merozoites. When the erythrocytic cell ruptures due to the 3,000-4,000 merozoites produced, symptoms of fever and chills are induced within the host. This life cycle is extremely damaging to children; persons under the age of 5 account for 86% of malaria fatalities. Malaria has other characteristic effects, such as yellowing of the skin/eyes (jaundice), sweating, vomiting, weakness, and nausea. Current mortality rates in Africa are 9.33% per 1000 children, which represent 28.2% of all fatalities for those under five. The story changes dramatically as the host

Malaria or other similar diseases like malaria has been recognized and encountered by humans for more than 4,000 years. Malaria is caused by the genus Plasmodium parasites, which enter the human body and are transmitted to people through the bite of a mosquito infected with the parasite (Q&A, Malaria). Once the parasite enters the human body, the parasites multiply in the liver and then infect red blood cells. The malaria parasite was first discovered on November 6, 1880, by a French army surgeon named Charles Louis Al phonse Laveran. While stationed in

The symptoms of yellow fever are varied. The virus has an incubation period of three to six days. The first symptoms will be fever, muscle pain, backache, headache, shivers, and loss of appetite, nausea, and vomiting. Frequently a slow pulse accompanies the fever. Most people improve after three to four days, however in 15% of the cases; patients go into a toxic phase within 24 hours. Fever reappears, and they exhibit jaundice and abdominal pain with vomiting. Bleeding occurs from the mouth, eyes, nose and stomach. The kidneys fail to produce urine, and blood appears in the vomit and feces. Half of the patients who experience this toxic phase die in ten to fourteen days. Due to the fact that many of these symptoms are identical to malaria and other diseases native to the areas, yellow fever is difficult to recognize. Blood tests can identify the virus, but may not be easily available to people in poorer developing countries.
