QUESTION

How is malaria spread?

ANSWER

Malaria is caused by a parasite called Plasmodium, which is transmitted via the bites of infected mosquitoes. In the human body, the parasites multiply in the liver, and then infect red blood cells. Usually, people get malaria by being bitten by an infective female Anopheles mosquito. Only Anopheles mosquitoes can transmit malaria and they must have been infected through a previous blood meal taken on an infected person. When a mosquito bites an infected person, a small amount of blood is taken in which contains microscopic malaria parasites. About 1 week later, when the mosquito takes its next blood meal, these parasites mix with the mosquito’s saliva and are injected into the person being bitten.

Because the malaria parasite is found in red blood cells of an infected person, malaria can also be transmitted through blood transfusion, organ transplant, or the shared use of needles or syringes contaminated with blood. Malaria may also be transmitted from a mother to her unborn infant before or during delivery (“congenital” malaria).


Malaria Infection Possibilities?

QUESTION:

How can malaria affect somebody if you far from mosquitoes?

ANSWER:

It is extremely unlikely for you to become infected with malaria unless you are bitten by an infected mosquito. In rare caces, there have been reports of people contracting malaria through blood transfusions, but in most places, blood donors with a history of malaria are not allowed to donate whole blood, and only plasma, thus preventing transmission through this route.
