TABLE 1.

Numbers tested and sensitivity of MV RT-PCR on NTS and wet and dry oral fluid samples compared to cases confirmed by detection of MV-specific IgM

Sample type	PCR result
	No. of IgM-positive samples	No. of positive samples	No. of negative samples	Sensitivity (%)	95% CIa	P value (vs IgM)
NTS	39	37	2	95	83-99	0.49
