About Malaria

Malaria is a disease of the blood that is caused by a parasite transmitted from person to person by certain types of mosquitoes. Malaria symptoms, which appear about 9 to 14 days after the infectious mosquito bite, include fever, headache, vomiting and other flu-like symptoms. If drugs are not available for treatment or if the parasites are resistant to them, the infection can lead to coma, severe life-threatening anemia, and death by infecting and destroying red blood cells and by clogging the capillaries that carry blood to the brain (cerebral malaria) or other vital organs. Worldwide, malaria causes around 350 to 500 million illnesses and more than one million deaths annually.

Malaria is particularly devastating in Africa, where it kills an African child every 30 seconds. Many children who survive an episode of severe malaria may suffer from learning impairments or brain damage. Pregnant women and their unborn children are also particularly vulnerable to malaria, which, during pregnancy, is a major cause of mortality, low birth weight and maternal anemia. And while we know malaria is preventable, the lack of resources, coupled with a climate very hospitable to the deadliest strain of malaria, has made the disease a leading cause of death among African children.

In addition to the human toll malaria exacts, the economic and social impacts are also devastating: Sick children miss school, tourism suffers, and foreign investment is stifled. Annual economic loss in Africa due to malaria is estimated to be $12 billion, representing a crippling 1.3 percent annual loss in GDP growth in endemic countries. Malaria becomes a self-perpetuating problem, where the disease prevents the human and economic capital necessary to bring the disease under control. Moreover, malaria disproportionately affects the rural poor who can neither afford a bed net for prevention, nor access appropriate treatment when they fall sick.

Malaria is a preventable and treatable disease. As Senegalese president Abdoulaye Wade expressed recently, in order to be successful the fight against malaria must be a comprehensive one, which includes giving families and individuals insecticide-treated bed nets to sleep under, taking steps to kill mosquitos where they breed and when they enter houses to feed at night, and making anti-malarial drugs such as artemisinin-based combination therapies more widely available. At the same time, we must continue the search for a vaccine.
