What Causes Malaria?

Malaria is a parasitic infection transmitted from person to person by the bite of infected female Anopheles mosquitoes.
These mosquitoes usually bite from around dusk to dawn.
Once transferred to the human body, the infection travels to the liver where it multiplies and then enters the red blood cells.
Inside the red blood cells the parasites multiply rapidly until they burst, releasing even more parasites into the blood stream.
There are four main species of the malaria parasite: Plasmodium falciparum, Plasmodium malariae, Plasmodium vivax, and Plasmodium ovale.
P. falciparum is the main cause of severe clinical malaria and death.

Symptoms of Malaria
Malaria begins as a flu-like illness, with symptoms first occurring nine to 14 days after infection. Symptoms include fever (typical cycles of fever, shaking chills, and drenching sweats may develop), joint pain, headaches, frequent vomiting, convulsions, and coma.
If simple malaria is left untreated, it can become severe—around eight million malaria cases progress to severe malaria annually. Death from malaria may be due to brain damage (cerebral malaria), or damage to vital organs. The reduction of red blood cells can cause anemia.

Diagnosing Malaria
Diagnosing malaria is done with rapid dipstick tests or looking for the parasite under a microscope in a blood smear. However, rapid tests are not always available, microscopy is not always straightforward and, as a result, diagnosis based on symptoms is still normal in much of the developing world.
This means patients are often misdiagnosed and the real reasons for their symptoms go untreated. It also means antimalarial drugs are overused and go to waste when they are desperately needed.

Treating Malaria
The most effective treatment for malaria is artemisinin-based combination therapy (ACTs). ACTs have low toxicity, few side effects, and act rapidly against the parasite.
Today, 41 out of 54 African countries have officially changed their protocol to treat first-line malaria with ACTs. But in many places where MSF works, ACTs are scarcely available. The global need for ACTs is estimated to be at 300 to 500 million treatment courses per year, however, in 2006, drugs for less than 90 million treatments were purchased.
A three-day course of antimalarial pills for a baby can cost as little as $0.40.
Long lasting insecticide-treated bed nets are an important means of controlling malaria. In endemic areas, MSF distributes nets to pregnant women and children under the age of five, who are most vulnerable to severe malaria.
