Madagascar and Guinea circumsporozoite (cs) multiplex-bead assay (MBA) median fluorescence intensity minus background (MFI-Bkgd) values for Plasmodium falciparum, P. vivax210 and P. vivax247, arranged from lowest to highest, for specimens that initially tested positive using a cutoff value determined by the average MFI of the negative mosquitoes multiplied by two. Data points below the dashed line have an MFI-Bkgd value of less than 100. Open markers indicate specimens with an initial MFI-Bkgd value > 100 that also had a retest MFI-Bkgd value > 100
