Malaria

Malaria

Every year, malaria kills around  660,000 people and infects more than 200 million. Ninety percent of these deaths occur in sub-Saharan Africa.

Malaria is transmitted by infected mosquitoes. Symptoms include fever, pain in the joints, shivering, headache, repeated vomiting, convulsions and coma. Severe malaria, nearly always caused by the Plasmodium falciparum parasite, causes organ damage and leads to death if left untreated. MSF field research has helped prove that artemisinin-based combination therapy (ACT) is currently the most effective treatment for malaria caused by Plasmodium falciparum. In 2010, World Health Organization guidelines were altered to recommend the use of artesunate over artemether injections for the treatment of severe malaria in children.

Long-lasting insecticide-treated bed nets are one 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 and have the highest frequency of severe malaria. Staff advise people on how to use the nets.

In 2012, MSF used a seasonal chemoprevention strategy for the first time, in Chad and Mali. Children up to five years old took oral antimalarial treatment monthly over a period or three to four months during the peak season for the disease.

MSF treated 2,229,200 people for malaria in 2015.
