Answers
Malaria is a life-threatening mosquito-borne blood disease. The Anopheles mosquito transmits it to Humans a fact or situation that is observed to exist or happen, especially one whose cause or explanation is in question.
The parasites in mosquitos that spread malaria belong to the Plasmodium genus.
Over 100 types of Plasmodium parasite can infect a variety of species. Different types replicate at different rates, changing how quickly the symptoms escalate, and the severity of the disease.
Five types of Plasmodium parasite can infect humans. These occur in different parts of the world. Some cause a more severe type of malaria than others.Once an infected mosquito bites a human, the parasites multiply in the host’s liver before infecting and destroying red blood cells.
In some places, early diagnosis can help treat and control malaria. However, some countries lack the resources to carry out effective screening.
Currently, no vaccine is available for use in the United States, although one vaccine has a license in Europe.
In the early 1950s, advances in treatment eliminated malaria from the U.S. However, between 1,500 and 2,000 cases still occur each year, mostly in those who have recently traveled to malaria-endemic areas.What to know about malaria

Symptoms
Doctors divide malaria symptoms into two categories: Uncomplicated and severe malaria.Uncomplicated malaria
Malaria is passed on by the Anopheles mosquito.
A doctor would give this diagnosis when symptoms are present, but no symptoms occur that suggest severe infection or dysfunction of the vital organs.
This form can become severe malaria without treatment, or if the host has poor or no immunity.
Symptoms of uncomplicated malaria typically last 6 to 10 hours and recur every second day.
Some strains of the parasite can have a longer cycle or cause mixed symptoms.
As symptoms resemble those of flu, they may remain undiagnosed or misdiagnosed in areas where malaria is less common.
Malaria rapid diagnostic test Edit
A Malaria rapid diagnostic test is a blood test which can confirm a diagnosis of malaria in about twenty minutes. RDTs are not foolproof and have a number of drawbacks, and as such a negative rapid diagnostic test should not be accepted at face-value and follow-up with malaria microscopy is necessary.
Malaria microscopy
To see if patients have malaria, doctors may do a blood test. This test is called a Giemsa blood smear. Blood is put on a slide which is a thin piece of glass. The Giemsa stain is put on the slide. This stain helps doctors see the malaria. Then they look at the slide under a microscope. The Plasmodium is seen in the red blood cells.
Resistance to malaria
There are some children in Tanzania who are naturally immune to malaria. Researchers are using this to develop a new vaccine. U.S. researchers have found the children produce an antibody which attacks the malaria-causing parasite. Injecting a form of this antibody into mice protected the animals from the disease. The researchers plan to do tests on primates, including humans.
