^{^a}

Models adjusted for sex and age. All models clustered on the household level to account for within-household correlation and correct standard errors.

^{^b}

Nonbinary or sex data missing from 5 participants.

^{^c}

Non-Latinx participants who received PCR testing included participants who indicated the following racial identity categories: White (107 [28.1%]), Black (114 [29.9%]), Asian (61 [16.0%]), multiracial (21 [5.5%]), other (23 [6.0%]), NA (21 [5.5%]), and unknown (34 [8.9%]).

^{^d}

Non-Latinx participants who received serology testing included participants who indicated the following racial identity categories: White (89 [29.3%]), Black (80 [26.3%]), Asian (54 [17.8%]), multiracial (18 [5.9%]), other (19 [6.3%]), NA (25 [8.2%]), and unknown (19 [6.3%]).
