Malaria in pregnancy: challenges for control and the need for urgent action.

Malaria in pregnancy has a devastating effect on the health of mothers and their babies, and is an important cause of maternal and infant mortality and morbidity.1 The greatest effect of malaria in pregnancy is concentrated in sub-Saharan Africa and is associated with Plasmodium falciparum infection. However, pregnant women are also at risk of Plasmodium vivax malaria. Although its burden seems to be lower than that of P falciparum, P vivax malaria is still associated with harmful consequences for maternal and infant health.
