Malaria And Its Effects On Human Civilization

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).

Malaria (also called biduoterian fever, blackwater fever, falciparum malaria, plasmodium, Quartan malaria, and tertian malaria) is one of the most infectious and most common diseases in the world. This serious, sometimes-fatal disease is caused by a parasite that is carried by a certain species of mosquito called the Anopheles. It claims more lives every year than any other transmissible disease except tuberculosis. Every year, five hundred million adults and children (around nine percent of the world’s population) contract the disease and of these, one hundred million people die. Children are more susceptible to the disease than adults, and in Africa, where ninety percent of the world’s cases occur and where eighty percent of the cases

Background - Malaria is a water borne disease. It is spread by a parasite-carrying mosquito. It kills many people and reduces a country 's capacity to develop. There are different strategies to combat malaria. Around half the population is at risk of malaria and this disease is active in 106 counties across Africa, Asian and the Americas (see source 3). the global annual mortality from malaria is between 1.5 - 3 million deaths, or between 4000 and 8000 each day. Developing countries are most vulnerable to Malaria and as shown on source 2 Malaria has been spread across many various other countries including in Europe, but these countries have eradicated Malaria.

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.

Before the research I knew malaria is a disease which occurs mostly in poor, tropical and subtropical areas of the world. I also knew people get malaria by being bitten by an infective mosquito.

There have been many attempts at preventing malaria, none of which have been very successful. These have usually involved protecting human beings from mosquitoes, the dreaded carriers

Fortunately this may all change as for the first time there is talk of wiping out malaria, mostly if not entirely from human existence. To first understand how this is possible, we must first discuss why is malaria, such a big problem and why is it so efficient in what it does. Malaria is commonly found parasites, including Plasmodium falciparum, P. vivax, P. ovale, and P. these parasites commonly infects mosquitoes which feed off of the blood of various animals including humans. Interestingly, only female mosquitos are able to host the parasites needed to spread malaria. When the mosquito puncture people with their hypodermic like nose to drink the blood, typically a bit of the blood is regurgitated and when this is done, some of the mosquito spit is also put back into the person. In the spit exists the parasites which are responsible for the symptoms of malaria. Once the parasites are in the body, they will begin to make their way to the liver and eventually infect a large amount of liver cells until the parasites are mature. Once some of the parasites are mature, some will enter the bloodstream while others will remain dormant within the liver to ensure that not all of the parasites are

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 illness associated with the malaria parasite was first thought to be a result of poisonous mists drifting from marshes hence its name meaning “bad air” in Italian. Of course it was unbeknownst back then that it was actually caused by the female anopheles mosquito which tends to live near still water such as marshes.2 Although it was unknown what actually caused the symptoms of malaria,

In the seventeenth century a group of Jesuits brought back tree back that had quinine in it from Peru. This proved to cure malaria and was a major step in malaria treatment. The complexity of the malaria parasite is astounding, as it has six separate cycles in which half occur in the mosquito and half occur in the human body. Due to this extremely complex life cycle, there is no easy way out to target one point, and to fully eradicate malaria the entire global population would have to be on anti-malarial pills for the entire life cycle of a mosquito.

In areas where malaria thrives, human populations have been known to suffer in its clutches. Malaria is a tropical disease that causes thousands of deaths worldwide. However, a majority of malaria cases and deaths occur in Sub-Saharan Africa. The prevalence of malaria in African countries places a heavy burden on its people and affects all aspects of society. Considered both a consequence and a fundamental cause of poverty, malaria has a host of negative effects that hinder the growth and well-being of the African population.

In poor countries children and pregnant women are the most affected by the disease. Africa is one of the most affected countries in the world. One reason for this is the climate. Another reason is the lack of funding. Two to three billion dollars is needed per year to fund malaria control programs. But around only two hundred million dollars is spent on malaria control by African and UN agencies. Some say that malaria could be the cause of poverty rather than the consequence. Unlike other diseases, malaria is not caused by poor hygiene or unsafe drinking water. The difficulty in controlling malaria is mainly due to climate and ecology. To get rid of malaria completely would require a well run organization and a lot of

About 3.3 billion people, that is about half of the world’s population are at risk of contracting malaria (figure 1). Every year there are 250 million cases of malaria, and nearly 1 million deaths. That amounts to 2,732 deaths per day. Out of those million people that die every year, 800,000 of them are African children under the age of 5. To control malaria three actions need to be taken: insecticides need to be used to decrease the vector population, people have to be educated as to how to prevent the vector from reproducing, and anti-malarial drugs need to be distributed. To understand the vector and what the vector is, scientists had to first discover what the parasite was and how it worked. It was not until the year 1880 that French Physician Charles Laveran discovered that Malaria was caused by a protozoan in the genus Plasmodium (Malaria, 2013)

Malaria is one of the ten most common, yet deadly diseases in the world. It is a parasitic disease spread by the bite of Anopheles mosquito, which is active between dusk and dawn. Malaria occurs in over 100 countries and territories.
