Sub-microscopic infection (SMI) prevalence and proportion by Plasmodium species

Species	Microscopy		PCR		Prop SMI*
Mono or mixed infections
Plasmodium falciparum	47	(2.3%)	145	(7.0%)	67.6%
Plasmodium vivax	2	(< 0.1%)	137	(6.6%)	98.5%
Plasmodium malariae	0	(0.0%)	41	(2.0%)	100%
Plasmodium ovale	0	(0.0%)	7	(0.3%)	100%
Mixed infections	0	(0.0%)	42	(2.0%)	100%
N individuals infected by any Plasmodium species	49	(2.4%)	285	(13.8%)	82.8%

Percentages refer to population prevalence of the different infection types.

^*Proportion of infections which were submicroscopic (SMI): $\text{Prop SMI}=\frac{\text{PCR positive}–\text{Microscopy positive}}{\text{PCR positive}}$.
