RR, Relative risk.
Analyses were limited to adults with positive SARS-CoV-2 IgG test results. Bivariable Poisson regression models were constructed with number of self-report of any SARS-CoV-2 symptoms as the continuous dependent variable and age, sex, household size, and household sick contacts as the independent variables. Crude RR and 95% CI were estimated. Multivariable models included all variables from the bivariable models, and state of residence. Adjusted RR and 95% CI were estimated. Bold indicates statistical significance (P < .05).
