Evaluation of 2nd-generation CHIKV E1 detection RDT version B in clinical samples

IgG/IgM	PCR	IC RDT		Sensitivity	Specificity	OAA
		(+)	(−)
(−)	(+)	4	1	80.0		92.5
	(−)	2	33		94.3
(+)	(+)	7	14	33.3		47.5
	(−)	7	12		63.2
Total	(+)	11	15	42.6		70.0
	(−)	9	45		83.3

IgG/IgM (−): anti-CHIKV IgM- and IgG-negative cases

IgG/IgM (+): anti-CHIKV IgM- or IgG-positive cases

Sensitivity: percentage of matches between results of PCR and IC RDT in PCR positive samples

Specificity: percentage of matches between results of PCR and IC RDT in PCR negative samples

OAA overall agreement (percentage of total matches between results of PCR and IC RDT)
