Comparing Employees Who Tested Positive for SARS-CoV-2 Against Other Employees Involved in a Significant Exposure During an AGP

Variable	Significant Exposure During AGP and Tested Negative for SARS-CoV-2 (n=222), No. (%)	Significant Exposure During AGP and Tested Positive for SARS-CoV-2 (n=3), No. (%)	P Valuea
AGP involved in the exposure?b	222 (65.9)	3 (37.5)	.13
Reason for significant exposure
Any Lack of respirator during AGP	203 (91.4)	3 (100)	1
Any lack of eye protection	26 (11.7)	2 (66.7)	.04
Lack of respirator and eye protection during AGP	12 (5.4)	2 (66.7)	.01

Note. AGP, aerosol-generating procedure.

^a The Student t test was used for continuous variables. The Fisher exact test was used for categorical variables.

^b Total with significant exposure and tested negative = 337; total with significant exposure and tested positive = 8 including exposures not involving an AGP.
