Study specimen collection, RSV prevalence results, and sensitivity by specimen type

Study specimens	N	Percentage with this specimen type	n positive by specimen	% positive overall	Percentage of all positives identified by this specimen type	95% CI	RSV positives from any source among patients with results by that specimen type	Sensitivity*	95% CI
Overall	1766	100.0%	109	6.2%	N/A	N/A	109	N/A	N/A
NP swab	1766	100.0%	56	3.2%	51.4%	42.0–60.8%	109	51.4%	42.0–60.8%
Saliva**	1740	98.5%	75	4.3%	68.8%	60.1–77.5%	107	70.1%	61.4–78.8%
Sputum	606	34.3%	41	6.8%	37.6%	28.5–46.7%	57	71.9%	60.3–83.6%
Serology	367	20.8%	23	6.3%	21.1%	13.4%-28.8%	29	79.3%	64.6–94.1%

*Sensitivity is limited to those with results with that specimen type, i.e., count of positives by that specimen type divided by count of all positives from any source among those with results by that specimen type

**In subjects that were unable to produce saliva, a saline mouth wash was obtained
