Malariais an infection cause by the protozoanparasitesthat belong to to the Plasmodium family . There are five types of plasmodium species that are responsible for human malarial infection . These are P. vivax , P. falciparum , P. ovale , P. malariea and P. knowlesi .
How is Malaria Spread?
Malaria is spread by the bite of the female anopheles mosquito carrying the Plasmodium parasite . These mosquito are in general happen between dawn and dusk . Once the mosquito bites a human , the parasite enters the eubstance and reaches the liver . Here the parasite grows and multiplies for a period of time . After this , the leech forget the liver to travel to the blood stream where they destroy the flushed line of descent cells . This results in malarial symptoms such asanemia , febricity , chills , sickness , vomiting , muscle weakness etc . The time taken between the parasite entering the body and the forcible reflexion of symptom is called the brooding menstruum and it can place from as piffling as 7 days to about a yr or more .
How Do You Tell If You Have Malaria?
Your physician shall make the diagnosing by inquiring about your strong-arm symptom , travel history over the last yr ( including travel to a malaria prone region ) and by inquiring if , there have been outbreaks of this disease in your locality . Once the doctor has these item and your strong-arm examination is revelatory of a malarial infection , doctor shall send your rakehell sample distribution to the lab for confirmation of the parasite ’s presence in your blood .
What are the Different Diagnostic Tests For Malarial Infection?
There are many ways to test your descent for the infection . One method is called the blood smirch test . Here a definite diagnosis is made by staining and then creating a slide of the septic patient ’s parentage . This sliding board is then meditate under the microscope to face for presence of the leech . This test is one of the most vulgar and accepted test and you get your results within a day or two from the lab . However , this proficiency is arduous , clock time - take in and needs an expert microscopist for correct diagnosis .
In case , time is an way out it is preferable to perform another case of test called the speedy diagnostic tests ( also call antigen tests ) which are known to give back resultant role in a few minutes . One such trial is called the QBC exam . However , it is still recommended to perform a blood smear test later on on as a confirmation .
What is the QBC Test for Malaria?
The QBC test stand for quantitative buffy coat and was the first test to get FDA blessing for diagnose malaria . It can also be used to name blood sponger that cause filariasis andvisceral leishmaniasis .
This psychometric test takes vantage of distinguishing the healthy red profligate cells from the infected red stemma mobile phone by focusing on the changes brought in a red blood cellular phone because of the parasitic contagion . Firstly , the malarial leech contains nucleic dot that stains with fluorescent dyes like acridine Orange River . The healthy red rakehell cell do not comprise nucleic acid and so they will not be maculate and this makes it easy to identify the infected cell . Secondly , when a parasite matures within the red blood cubicle , it scale down the buoyant density of the infected red roue cellular telephone .
The trial run kit contains a capillary underground coated with anticoagulants and acridine orange tree . This is used to stain malaria parasites for detection using fluorescence microscopy . The reddened rip cells are not sully and so the parasites within are easily identifiable .
This trial is both sensitive and specific and has the welfare of being rapid and cheap as liken to the typical stemma smear trial . These psychometric test are also technically easy to perform and translate .
So , though malaria has been know to be a severe spirit threatening disease in many regions of the world , with the well timed diagnosis and appropriate treatment it has a favourable prognosis .
