The purpose of this is to determine the impact of intermittent preventive treatment (IPT) with sulfadoxine-pyrimethamine (SP) on the morbidities associated with malaria in pregnant women and newborns in rural peri-urban areas of Bobo-Dioulasso, 5 years after its implemented.

Malaria in pregnant women is a crucial issue in Burkina Faso. Faced with this problem, a strategy based on the use of treated nets and intermittent preventive treatment (IPT) based on sulfadoxine-pyrimethamine (SP) was adopted in 2005. Five years after its implementation, the investigators will check whether this strategy is still effective in the preventing maternal and congenital malaria on the one hand and maternal anemia, low birth weight and prematurity on the other hand.
