Malaria
- Malaria is a life-threatening disease caused by parasites that are transmitted to people through the bites of infected mosquitoes.
- A child dies of malaria every 30 seconds.
- There were 247 million cases of malaria in 2006, causing nearly one million deaths, mostly among African children.
- Malaria is preventable and curable.
- Approximately half of the world's population is at risk of malaria, particularly those living in lower-income countries.
- Travelers from malaria-free areas to disease "hot spots" are especially vulnerable to the disease.
- Malaria takes an economic toll - cutting economic growth rates by as much as 1.3% in countries with high disease rates.
How can you write a conclusion of the topic Malaria?
Malaria has become one of the most challenging infectious diseases to eradicate in Africa. The overall disease burden is devastating youth, women, and health systems. Malaria accounts for 40% of public health expenditure, 30% to 50% of inpatient admission, and up to 50% of outpatient visits in endemic regions. It has affected Africa's human resources and directly lowered its annual economic growth. It not only debilitates the workforce, but keeps children from going to school, prevents pregnant mothers from effectively caring for their families, and decreases the likelihood of a healthy pregnancy outcome. Governments and donors have recognized this extraordinary toll and have increased their commitment toward prevention, treatment, and eradication. More successful programs have included reducing tariffs on ITNs to make them more affordable, incorporating infectious disease in reproductive health programs, and intermittent preventive treatment. With sustained governmental commitment and financial resources, the eradication of malaria can succeed.
Which insect transmits malaria?
A mosquito, every 30 seconds kids in parts of Africa get malaria. if they had bed nets ( nets that go over beds), they would be safer.
The female Anopheles mosquito is the vector for the malarial parasite.
How is malaria spread from person to person?
Malaria is spread by female mosquitoes. The parasite which causes malaria is found in the female mosquitoes saliva. When a person is bitten by a female mosquito, the parasite enters the bloodstream via the mosquitoes saliva.
However, there are also other ways for malaria to be spread. A pregnant woman can pass malaria onto her baby. Someone using a needle that has been used by a person with malaria can infect that person. Having a blood transfusion from someone who has malaria can also pass it on to someone else.be careful.
Yes. However, it is a recurring infection, so you never totally "survive" it. One you contract it, you will have it the rest of your life.
What is the ANTONYM and synonym for the word malaria?
Malaria is a disease brought about often by mosquitoes, so... I suppose the antonym to "disease" would be "cured," "immune," or "unblemished."
I don't think that malaria itself has an antonym.
What would be observed in the blood smear of patient who has malaria?
sBoth thick and thin blood smears are taken from the finger tip of earlobe of malaria patient. This smear is kept in water to dissolve and remove the haemoglobin from the slide. The slide is stained and visualised under oil immersion lens to see the malaria parasites directly.
The MCV Lab Test is a kind of Hemotology Test. The results are derived from Hct, Hgb, and RBC count from a blood sample. MCV stands for Microtic cell volume, the test is an indicator for the size of the RBC's or red blood cells. It helps to determine if there is risk for certain anemia's. Tonya Fisher, LCNS Corbett, J.V. (2008) Laboratory Tests and Diagnostic Procedures with Nursing Diagnosis. (7th ed.) New Jersy: Person
Mean corpuscular volume (MCV) is a measurement of the average size of your RBCs (red blood cells). The MCV is elevated when your RBCs are larger than normal (macrocytic), for example in anemia caused by vitamin B12 deficiency. When the MCV is decreased, your RBCs are smaller than normal (microcytic), such as is seen in iron deficiency anemia or thalassemias.
Can malaria recur after several years?
Apparently yes!
My husband contracted Dengue about 3 years ago in Bali and now has a recurrence of it, although milder than before he is still feeling very tired and generally unwell.
What I'm not sure of is if this is something that stays in your system or was he bitten by another Dengue carrying mosquito here in Bali?!
Who invented malaria parasite?
One of the parasites (Plasmodium sp.) that causes Malaria was discovered in 1880 by French army doctor Charles Louis Alphonse Laveran while working in Algeria.
Plasmodium was found to be present in the red blood cells of infected people.
Why heterozygous for sickled cell anemia are resistant to malaria?
Because individuals who inherit the gene from only one parent produce red blood cells which are distorted. This distortion makes the cells unpalatable to malaria parasites, without seriously harming the individual. This tends to protect against malaria and that protection causes selection for this allele. Individuals who get the sickle cell gene from both parents suffer serious distortion of the red blood cells. This protects against malaria, but also reduces the oxygen-carrying capacity of the red cells to a dangerous degree. This causes a disease called sickle-cell anaemia, which causes selection against the gene. In malarial regions a balance is established. When a population with sickle cell alleles moves to an area with effectively no malaria present, the sickle cell alleles are steadily selected against. This shifts the balance steadily towards low levels.
The mosquito injects its saliva containing parasite into the bloodstream. These parasites travel then travel to the liver where they develop, multiply, and rupture. They go back to circulation and enter the red blood cells eventually attacking and destroying them. The parasites in the red blood cell do not go back to the bloodstream. Instead, they block the small blood vessels in the brain and lungs that may cause the patient to go into coma and eventually, death.
Mosquitoes belonging to the Genus Anopheles.
Reptile Aves and Mammals are primary host of plasmodium
How can you reduce the spread of malaria?
As for Dengue.... Also known as break bone fever- it is very painful and spread by mosquitoes in tropical areas. It is usally found in the coastal area of Mexico. It takes up to 3 to 14 days after contractng the virus you may develop high fever, muscle and joint pain. There is no vaccination or cure. The prevention is avoiding mosquitoe bites & using Insect repellent containing DEET or PACARIDIN. Wear long sleeves and long loose pants and no sandals.
How can malaria be controlled by humans?
Anyone who goes to malaria infested areas must take a shot for immunity or while in the area take a pill for temporary immunity. Feel free to add to this answer; it is not complete.
Structure and size of the pathogen that causes the disease?
Yes, if the structure of the pathogen virus is really complex and strong then the cause and effect of the disease is greater whereas if you have a virus that has the same structure of the common cold but slightly different, that's not really going to make the next epidemic.
What is the parasite that causes malaria?
THere are 3:
- Plasmodium vivax/ovale: you get tertian (48 hour cycle) fevers, and this one can stay dormant in your liver so you need to treat it with primaquine to kill it there also on top of chloroquine.
- Plasmodium falciparum: The most common and the worst one to get. Severe, daily fever cycles. The RBC's c the parasites can occlude capillaries in the brain = cerebral malaria, kidneys, and lungs.
- Plasmodium malariae: Quartan (72 hour) cyclic fever, headache, anemia, splenomegaly.
You ID these on blood smear and the vector is a mosquito.
Scientific name of malaria parasite?
There are actually four species of protists that can cause Malaria.
- Plasmodium falciparum
- Plasmodium vivax
- Plasmodium ovale
- Plasmodium malaria
Plasmodium falciparum is the most widespread and dangerous.
How many people die of malaria in a day?
I do not know, but I think it is many a year, like 3000 or something THE END That is about right - it is difficult to work out as what constitutes a child? The World Health Organisation estimate that in 2006 there were over 1000000 deaths as a result of malaria and most are children. http://www.who.int/mediacentre/factsheets/fs094/en/index.html
Which organ does the disease malaria affects?
yes, it does. the parasites actually get in there it sounds like, and can kill liver cells.
Yes. That is the main focus on Malaria. When the parasites are injected into the bloodstream by the Anopheles mosquitos the pathogens use the blood stream to flow straight to the liver. This is where the parasites will begin to attack the red blood cells. The liver cells more or less go with it.
