INTREPiD is a two-arm, open-label, parallel-assignment randomized trial of a strategy of 1st trimester screening for P. falciparum parasites with a high-sensitivity rapid diagnostic test (HS-RDT). Participants will be women of all gravidities presenting to antenatal clinics in the 1st trimester in sites endemic for P. falciparum malaria in Kenya and the Democratic Republic of the Congo.
Following consent and enrollment, women will be allocated 1:1 to either usual antenatal care or to the intervention. The intervention will be a single screening in the 1st trimester for P. falciparum infection in maternal peripheral blood with a HS-RDT. Women who test positive for P. falciparum on HS-RDT testing will be treated with a single course of Artemether-Lumefantrine (AL) and then returned to usual antenatal care.
Participants will be followed through delivery and then through their offspring's first month of life.
The Hypothesis is that, compared to usual antenatal care, screening women in the 1st trimester for P. falciparum and treating them if positive with AL will reduce the risk of an adverse pregnancy outcome.
