Prevalence of SP resistance molecular makers in Burkina-Faso and Mali among parasitaemic women at their antenatal booking visit (pre-SP). Notes: dhfr /dhps alleles (Top panel) and dhfr haplotypes (Bottom panel). Mutant allele frequencies are represented in the top panel graph by horizontal bars. Lines depict the 95% confidence intervals. The presence of “0” represents the absence of point mutations for a designed codon. The bottom panel represents the frequency of dhfr haplotypes (N51I, C59R, and S108N) per country.
