Explain what causes malaria and how the disease is spread?
Malaria is a potentially fatal tropical disease that is caused by a parasite known as Plasmodium. It is spread through the bite of an infected female mosquito. Malaria is transmitted to humans from the Anopheles mosquito. *Each year, there are approximately 515 million cases of malaria, killing between one and three million people, the majority of whom are young children in Africa. *Ninety percent of malaria-related deaths occur in Africa. Malaria is commonly associated with poverty, but is also a cause of poverty. *Malaria is one of the most common infectious diseases and an enormous public health problem. *Young children are more prone to getting Malaria than adults are. *Malaria is a disease which kills a child every 30 seconds across Africa.? *In Tanzania malaria is the leading killer of children. ? Symptoms of malaria are fever, shivering, joint pain, vomiting, anemia, hemoglobinuria (when your urine tturns red), retinal damage, and convulsions. The classic symptom of malaria is occurrence of sudden coldness followed by rigor (shaking) and then fever and sweating lasting four to six hours, every two days.
Malaria is a protozoan infection carried by mosquitoes. Falciparum malaria is the most common virulent type. 40% of the world's population is at risk every year.
It has killed 3+ billion people over the years and it infects 500,000 every year.
People with the infection will have chills, fever, sweats in cycles of 49 or 72 hours depending on the microbe and the cycle can last for weeks without relief.
There is a high death rate in the acute phase especially in kids.
Prevention: vector control, bed netting, screens, repellants, The drug of choice is
Chloroquine.
Malaria is an entirely preventable disease, and many people (over half a million per year) die needlessly from it.
Malaria is transmitted by the bite of the female mosquito. The parasite enters the body via the mosquito's saliva and proliferates throughout the bloodstream. There are many ways in which this can be prevented.
1) Don't get bitten. It seems obvious, but this is actually a serious point. Many people, especially in rural areas of sub-Saharan Africa are massiely ill-informed about malaria. By using a combination of insecticide and malaria nets (known as vector control), the mosquito is less able to bite and the infection less able to spread. Only around 30% of households in sub-Saharan Africa currently have mosquito nets..
2) Antimalarial drugs are available. Quinine, the first antimalarial, is still a widely used drug. Analogues such as chloroquine and mefloquine are also commonly used. A problem with these sort of drugs is that many malarial parasites have evolved to become immune. Drug development to find different analogues which do not invoke an immune response is currently occurring.
The main reason that people die from malaria is that they do not have the education to seek preventative measures, or the money or resources to seek treatment. Malaria is nowhere near as prolific in the Western world where treatments are available and people are well-educated on the dangers.
So yes. It's preventable.
black water fever is a complication of malaria characterized by hemolysis,hemoglobiuria and kidney failure caused byplasmodium falciparum
Is malaria a vector borne disease?
Yes it is the most deadly vector borne disease, Malaria, kills over 1.2 million people annually, mostly African children under the age of five. Dengue fever, together with associated dengue haemorrhagic fever (DHF), is the world's fastest growing vector borne disease.
How do you treat malaria disease?
they have gotten rid of the most areas where water piles up, such as bird baths, ponds, and other water sources that. This helps because this is where the mosquitos "hang out" and lay their eggs. If we all get rid of our places where water can pile up, What_has_the_government_done_to_slow_the_spread_of_malariawill be controlled in a better way! (not lakes, and ponds.) TRY THIS! if you have a swimming pool in your yard, cover it up when not in use! hope i helped save several lives!
What are the four types of malaria?
In humans, malaria is caused by female Anopheles mosquito. The five types are Plasmodium vivax, Plasmodium malarie Plasmodium ovale, Plasmodium falciparum, and Plasmodium knowles.
What are the four species of plasmodium that cause malaria?
You have four species of Plasmodium which causes malaria in humans. They are Plasmodium vivax, P. falciparum, P. ovale and P. malariae.
If malaria were eliminated how might the frequency of the sickle-cell allele change over time?
Since people with the sickle cell allele trait are resistent to malaria, if malaria were eliminated there would be no change in the frequncy of sickle cell allele. This is because the presense of malaria does not have an affect on patients with the sickle cell allele trait.
Has malaria killed more people than all wars?
I think disease has by far the highest death toll. The truth is, human beings are constantly being consumed by bacteria, as the body ages it loses its ability to replenish what bacteria consume. What causes you to get sick, regarding bacteria, is not so much their pressence there, but the fact that they eat your tissues and take a dump right there and then. Bacteria use the human body both as a pantry and a toilet, and bacterial feces, well different kinds produce different chemicals which affect the body in a different way. A doctor's job, is to find what chemicals will kill breeds of bacteria without harming the body. Medicine boils down to chemistry, chemistry that is, as to how it applies to the human body. Increasingly though, Physics is rapidly becoming more and more a part of medicine; in the future, Doctors will need a knowledge of physics, as well as chemistry, the old time doctors are rapidly going the way of the dodo. By "old time" I mean, doctors who only study chemistry and human biology; in the future, doctors will study physics, specifically the body's bioelectrical system which is an understudied area of medicine, chemistry, in addition to human biology. Earning a medical degree, will be that much harder, but medicine will hopefully be that much better.
How is malaria passed through humans?
Malaria is not passed Human to Human unless when the an infected blood has been transfused to another healthy human. Malaria is an insect borne disease, you can be able to get it through a mosquitoe bite from a malaria infected mosquitoe.
Why is it good to kill mosquitoes to control malaria?
Malaria is in fact a plasmodium parasite. These are microscopic organisms called protist. Malaria is an extremely infectious, or communicable, disease. It destroys the red blood cells in your body as they are the reproduction factories of the parasite.
Malaria is a very dangerous disease, killing between one and three million people a year, mostly children. Most Malaria cases, however, occur in sub-Saharan Africa.
The malaria parasite is spread by the Anopheles Mosquito, which is the only mospuito that can transmit the disease. The Anopheles Mosquito is one of the targets of spraying, along with other mosqitos, mainly ones carrying the West Nile virus.
Why malaria cases are increasing?
Because mosquitos are more resistant to chemcals designed to kill them, And your gay
What is the Herbal drug is used to cure malaria?
Lime and lemon play a vital role in the treatment of quartan type of malarial fever. About three grams of lime and a juice of 1 lemon should be dissolved in about 60 ml of water. This mixture can be taken before you suspect the attack to take place.
Why can't humans become immune to malaria?
it hasn't been developed. its a virus from the protista kingdom. so it cannot be healed only managed. Viruses don't leave your body once you get them. they just lay dormant inside your body after they have been healed. they're virtually impossible to kill
What is Malaria's portal of exit?
Malaria is caused by a protozoan parasite called Plasmodium. The parasite infects the liver cells and red blood cells of the host. One part of the life cycle involves the formation of male and female gametocytes in the hosts blood. The gametocytes are ingested with the blood-meal when a mosquito bites the person. The gametocytes unite and form a zygote, which grows into the "adult" form of the parasite in the mosquito. This adult form (sporozoite) can infect another person when that mosquito bites someone else.
What areas of the body are affected by malaria?
Liver, blood vessels, kidney etc are worst effected by malarial parasite. The germs of malaria at times become dormant in the liver and as and when get opportune atmosphere, over power the human body metabolism.
How long does it take you to die from malaria?
you do not always die from Malaria even if it is untreated. Google it
Why are people with sickle cell trait resistant to malaria?
Not sure if this is right but could it be because the blood cell does not contain enough oxygen for the parasite to survive?
By what protozoans is malaria caused by?
Yes, malaria is caused by protozoa, namely Plasmodium species. There are 5 Plasmodium species that can cause human infections: P. falciparum, P. vivax and ovale, P. malariae, P. knowlesi.
P. falciparum can invade red blood cells of all ages, may also be drug-resistant and is responsible for most severe and life-threatening malignant tertian malaria.
What is the relationship between sickle-cell disease and malaria?
G6PDD does not protect against malaria infection. People with G6PD Deficiency can still get it like anyone else. The malaria larva has to have mature red blood cells to live in and cannot survive in immature ones. An rbc's normal life span is 120 days, but due to hemolysis, many do not live this long. The faster death of rbc's also causes the malaria larva to die as well. There are two problems with this. The first is obvious as hemolysis (death of rbcs) also causes us problems. Although G6PD Deficient people are spared the severe symptoms of malaria, they have to weather hemolysis and must rely on their ability to make new rbcs. The infection is still sequestered in their liver. The second is that there is no anti-malarial medication that is friendly to G6PD Deficient people.
Malaria is dangerous and precautions should be taken to avoid infection. Anti-malarials are not an option. You can learn more about this at g6pddeficiency.org.
Mainly in mosquitos, if it lives in you, chances are you got maleria...
In which season is malaria most common?
in rainy season malaria is more common because mosquito get enough water for breeding
