824 Questions
How easily can malaria spread?
very,
Well over 300 million people around the world suffer from Malaria and in Africa, someone is bitten every second by a mosquito infected with Malaria. (:
Where was Malaria contracted during World War 1?
My great grandfather went to India with his regiment during WW1 and contracted Malaria there.
What research has been done on malaria?
A new longer-lasting vaccine shows promise, attacking the toxin of the parasite and therefore lasts longer than the few weeks of those vaccines currently used for malaria prevention.
Malaria is actually caused by a protist that belongs to the genus of Plasmodium.
no, malaria is not inheritable. it's a fever and disease that was caught by mosquitoes and other bugs biting you and after contact by infected humans, but in my social studies it is not inheritable as parent to offspring.
What is the size and structure of the malaria parasite?
The various subgenera are first distinguished on the basis of the morphology of the mature gametocytes. Those of subgenus Haemamoeba are round or oval while those of the subgenera Giovannolaia, Huffia and Novyella are elongated. These latter genera are distinguished on the basis of the size of the schizonts: Giovannolaia and Huffiahave large schizonts while those of Novyella are small.
What is the total number of deaths from malaria?
Most malaria related deaths occur in Africa. Most at risk are children below the age of five and pregnant women.
WHO places at about 1.272 million deaths per year world wide in 2002, according to the WHO World Health Report 2004.
Due to various under reporting and malaria related complications the actual number is estimated to be as high as 3 million deaths per year. "Conquering The Intolerable Burden Of Malaria: What's New, What's Needed: A Summary" Joel G. Breman, Martin S. Alilio, And Anne Mills.
Why are children more prone to getting malaria than adults?
Because children eats anything that they come across and they also like playing in gardens where most insects are
The protzoal parasite that causes Malaria are
Plasmodium Vivax
Plasmodium Falciparum
Plasmodium Malariae
Plasmodium Ovale
It is an intracellular parasite that inhabits the Red Blood Cells and the liver.
P. Falciparum cause Cerebral Malaria.
What type of microbe causes malaria?
'Protozoans' is the term usually used to talk about the protists that cause malaria in humans or in other vertebrate erythrocytes. Protozoa belong to a large group of eukaryotic organisms that are single-celled. These are usually microscopic and include amoeba, ciliates, flagellates and sporozoans. In malaria, the protozoans can also be called 'malaria parasites.'
Transmission:
The sporozoan protozoa that cause malaria are transmitted through a mosquito feeding upon the blood of an infected host and ingesting a number of these parasites. The protozoa develop within the mosquito and are secreted through its saliva to infect other potential hosts when bitten. Once inside a human (or other vertebrate erythrocyte hosts), they can spend a protracted period (from weeks or months to, potentially, years) inside the host's liver and spleen, where they reproduce in the blood (specifically, within the red blood cells, erythrocytes).
Malaria is a vector-borne infectious disease caused by any of a number of protozoans spread by the female Anopheles mosquito. Only Anopheles mosquitoes can transmit malaria, and they must have been infected through a previous blood meal taken from an infected host. It is common in tropical and subtropical climates in endemic areas including much of Sub-Saharan Africa, Asia and the Americas. These locations have significant amounts of rain fall and consistent hot temperatures. These warm, consistent temperatures and moisture provide mosquitoes with the environment they need to breed continuously year round.
Scientific names:
The causative organisms include protists of the genus Plasmodium. The three most common organisms in malaria infections are P. vivax, P. ovale, and P. falciparum. Falciparum malaria is the most serious of the three, causing about 80% of all cases of human malaria and 90% of deaths, and is becoming more frequently drug resistant. Another less common type of Plasmodium that can cause malaria is P. malariae. A fifth type, P. knowlesi, is not thought to infect humans.
Prevention:
To prevent the disease, a person in the areas where these mosquitoes live should reduce the number of bites they receive. Mosquito netting used around beds can reduce the number of mosquitoes and bites and mosquito repellents also help.
Symptoms:
Symptoms of malaria are fever, shivering, joint pain, vomiting, anemia, hemoglobinuria (when your urine turns red), retinal damage, and convulsions. The classic symptom of malaria is occurrence of sudden coldness followed by rigors (shaking), then fever and sweating lasting four to six hours, which occurs every two days.
Other facts:
- Plasmodium falciparum - the common African type affects 80 - 85% of malaria patients, and is the most severe form of malaria. P. falciparum is also called a 'malign tertian malaria', malign means "evil", and this is the type which most often kills humans.
- Plasmodium vivax - Milder than Falciparum, is the second most common species to cause the disease malaria. It is also called 'benign tertian malaria', benign means "good", and this type usually doesn't kill humans.
- 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. Young children are more prone to getting Malaria than adults are.
- 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.
- Malaria is a disease which kills a child every 30 seconds across Africa.
Who normally gets the illness malaria?
Malaria infects between 300 and 500 million people every year in Africa, India, southeast Asia, the Middle East, Oceania, and Central and South America. A 2002 report stated that malaria kills 2.7 million people each year.
What is the name of female mosquito which causes malaria?
Sir Ronald Ross, who was born in India and British by nationality, discovered that female anopheles mosquito causes malaria. He called that mosquito as a mosquito with dappled wings, as he was not a zoologist.
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.
