What is malaria? \n\nMalaria is a serious disease that causes high fever and chills. You can get malaria from a bite by an infected mosquito. It is most often found in Africa, Southern Asia, Central America, and South America.\n\nWhat causes malaria? \n\nA bite from a mosquito infected with certain parasites causes malaria. In extremely rare cases, people can get malaria if they come into contact with infected blood, or an unborn baby (fetus) may get the disease from its mother. You cannot get malaria by being near a person who has the disease.\n\nWhat are the symptoms? \n\nMost malaria infections cause flu-like symptoms (such as high fever, chills, muscle pain, and diarrhea). Symptoms tend to come and go in cycles as the disease progresses. One type of malaria may cause more serious problems, including heart, lung, kidney, or brain damage and possibly death.\n\nHow is malaria diagnosed? \n\nA diagnosis of malaria is confirmed when you have a blood test that shows the parasite in your bloodstream.\n\nHow is malaria treated? \n\nMalaria often requires treatment with medicine (antimalarial medications). Most of the time antimalarial medications effectively treat the infection; however, some malaria parasites may survive because they are in the liver or are resistant to the medication. \n\nHow is malaria prevented? \n\nYou may prevent malaria by taking medicine before, during, and after travel to an area where malaria is present and by protecting yourself against mosquito bites. But, using medicine to prevent malaria does not always work. This is partly due to parasites becoming more resistant to some medicines in some parts of the world.

Malaria means "bad air."  It is caused by a parasite of the genus Plasmodium. There are four species that cause it: P. vivax, P. ovale, P. falciparium, and P. malariae.\nThese parasites are injected into your body during the bite of a Anophelese mosquito, or they can be passed from mother to baby.  \nOnce in the body, the parasites infect your liver, then your red blood cells.  Infected cells become filled with young parasites and burst open - killing the cell in the process.\n\nAll I know about the treatment of Malaria is that it can cause a G-6-PD deficiency anemia in some genetically predispositioned folks.  Sorry.

boarders, it's all about crossing boarders.\n\nEndemic: a disease that exists permanently in a particular region or population. Malaria is a constant worry in parts of Africa.\n \nEpidemic: An outbreak of disease that attacks many peoples at about the same time and may spread through one or several communities.\n \nPandemic: When an epidemic spreads throughout the world.

No, but they are both spread by mosquitoes. Yellow fever is spread by Aedes mosquitoes, but malaria is spread by Anopheles mosquitoes. Yellow fever is caused by a member of the Flavivirus family. Malaria is caused by parasites: Plasmodium falciparum, P. malariae, P. ovale\n\nYellow fever is vaccine-preventable. Malaria does not have a vaccine, but there are some prophylactic drugs and disease treatments.

That would be a two semester course in med or pharmacy school. I don't think the Yahoo managers would permit such a long answer to be posted.\n\nThere are different actions/mechanisms for each class of antibiotics.  They are given for bacterial infections of all sorts. Can you narrow the scope of the question any?  By the way, malaria is a protozoa, not bacterial, which is what antibiotics are directed against.

Homeostasis is a general concept in biology which you can look up on wikipedia. Malarial mosquitoes, like all organisms, need to maintain homeostasis in order to survive. Perhaps you are reading your homework question the wrong way.

Plasmodium parasites also undergo stages of development. There is a certain stage in their life cycle that they will have to go to a female mosquito body part to propagate and become the phase that is transmitted to humans through feeding. The same goes true also that female mosquitoes are the ones that bite and feed especially at night.Hope this helps. God bless

Malaria was discovered by Sir Ronald Ross, who was working in Secunderabad in the early 19th century.

Some experts feel that up to 95% of the North American population has at least one or more types of parasites living in their bodies. Authorities claim that we have more parasitic infections than some third world countries, and that Africa has less of a problem then we do!\n\nParasites release toxic wastes that are actually their feces and urine.  Parasites urine is practically pure ammonia.  Parasite waste can affect the kidneys, liver and immune system.\n\nHow do we get parasites?  If an estimated 95% of North American's have parasites, they must be very easy to get!  The primary way is from our food and water (over 50% of it is infected).  Organic food, often grown with animal manure, may be a greater source of parasites than commercial food.\n\nThe eggs of parasites are microscopic and are the real danger.  They can be passed sexually, as well as through shaking hands, walking barefoot, eating or drinking from someone else's glass, bottle, can, fork, etc.  Parasites can also be passed through swimming in polluted lakes, rivers, streams or even by going to the beach.\n\nWe can get parasites from our pets.  Anyone who is sick or has a health problem should try to remember when it started and when he or she got the pet.  You may find it was around the same time.  Every time that your pet licks it's anus, they are possibly putting thousands of parasites on their tongues.  When they lick you, those eggs are going right on you!  The link between a sick child and a new puppy is seldom realized.\n\nADVICE: There are two immediate goals for dealing with parasites. First, get rid of them as swiftly and safely as possible. Don't try to speed up their dismissal. Second, stay free of them. They are prone to return.\n\nP.S. (after your added comment) Please remember that most doctors in this country are not very informed on the issue of parasites. Once a diagnosis is made, your doctor will prescribe either drugs, such as Flagyl (metronidazole), which causes severe side effects--nausea and headaches--in about half of those who take it, or a natural regimen to irradicate parasites.

Malaria is a tropical disease caused by a protozoa from the genus Plasmodium (falciparum, ovale, vivax), and transmited by mosquitoes. This disease is some times mortal and is common near wet forests. It causes fever, anemia and headache. There are drugs agains it for many years, but nowadays there is increasing Plasmodiums resistence against there drugs. There is also experimental vaccine, but not yet commercially available.

prettylade has an excellent answer here. \n\nI wanted to add that malaria is an infectious disease though and if you or someone you know has this,you are required to let your doctor know prior to examination. \n\nPrecautions can then be taken to prevent others from contracting the disease.\n\nYou are putting many other lives at risk of contracting the disease if you leave it untreated or if you don't make others aware that you know you have malaria.\n\nI sincerely hope that you are just asking this question out of curiosity and that you are healthy and well.

The disease is spread through bites of infected mosquitos.\n\nhttp://health.yahoo.com/ency/healthwise/nord721

SYMPTOMS include fever, shivering, arthralgia (joint pain), vomiting, anemia due to hemolysis, hemoglobinuria, and convulsions. There may be the feeling of tingling in the skin, particularly with malaria caused by P. falciparum. Complications of malaria include coma and death if untreated—young children and pregnant women are especially vulnerable. Splenomegaly (enlarged spleen), intense headaches, cerebral ischemia and hemoglobinuria with renal failure may occur.\n\nCAUSED BY Infected female Anopheles mosquitoes carrying Plasmodium sporozoites in their salivary glands. Once an infected mosquito pierces a person's skin to take a blood meal, which they usually do starting at dusk and continuing throughout the night, the sporozoites enter the person's body via the mosquito's saliva, migrate to the liver where they multiply within hepatic liver cells asexually. Development in the hepatic cell takes 6 to 15 days depending on the species. Within hepatic cells the parasite replicates to produce hundreds or thousands of merozoites which, following rupture of the hepatic cell, are released into the blood stream and invade red blood cells.\n\nTREATMENT There are several families of drugs used to treat malaria. Chloroquine was the antimalarial drug of choice for many years in most parts of the world. However, resistance of Plasmodium falciparum to chloroquine has spread recently from Asia to Africa, making the drug ineffective against the most dangerous Plasmodium strain in many affected regions of the world.\n\nThere are several other substances which are used for treatment and, partially, for prevention (prophylaxis). Many drugs can be used for both purposes; larger doses are used to treat cases of malaria. Their deployment depends mainly on the frequency of resistant parasites in the area where the drug is used.\n\nIt is common in people from parts of the world where malaria is or was common, especially in West Africa or in descendents of those peoples. Sickle cell disease can occur in any individual of any color or ethnicity, however

One of the most common diseases in Africa is malaria, so there would be any number of ways to research that.  Also, I heard today on Ghanaian news that there has recently been a cholera outbreak in Accra.  There are any number of focuses you could choose.  You could work with child immunization (for polio or something similar), tuberculosis treatments, diabetes treatments, etc.  The field is wide open.

The bird flu isn't really dangerous now, but it has potential to become a serious threat. The main problem with bird flu is its high resistance to antibiotics. And everytime one of those few people with it are treated, there is the chance that new strains resistant to that treatment will develop. \n\nThe main difference between bird flu and malaria is that we generally have malaria isolated in africa, with few exceptions, where as we dont really know how far bird flu has spread. There's also vaccines to prevent malaria and drugs to treat it.\n\nAlso, bird flu hits and kills a person very fast.. typically wthin 3-4 days. The potential of the bird flu has been compared The spanish flu back in 1919 that killed 50-100 million people in a 1 year time span. In comparison, 1-2 million people die from malaria every year.

there are many mutations that happened to be beneficial to humans. for example, sickle cell anemia mutations created a positive effect in africa where malaria was prevalent
