*Values are percentage (no. persons worked onsite/no. persons scheduled to work) except as indicated. Worked onsite represents onsite only or hybrid work location. We excluded persons with only remote work experience before illness onset (560 for day before illness, 676 for day 1, 689 for day 2, and 677 for day 3) and those with missing work location (41 for day before illness, 74 for day 1, 55 for day 2, and 50 for day 3). aOR, adjusted odds ratio. †p<0.001 (comparison of % working onsite for specified day). ‡p<0.05 (comparison of % working onsite for specified day). §p<0.01 (comparison of % working onsite for specified day). ¶Dependent variable in the multilevel logistic regression models is worked onsite on a specified day (0 = did not work or worked remotely only, 1 = worked onsite [onsite only or hybrid]). Independent variables are work experience in a typical week before illness onset (0 = onsite only, 1 = hybrid), study period (0 = Prepandemic influenza seasons, 1 = COVID-19 pandemic period), PCR test result (0 = Other acute respiratory illness, 1 = Influenza or COVID-19), race/ethnicity, general health before illness, current smoker, type of employment, healthcare personnel, hours worked in a typical week before illness, employees discouraged from coming to work with flu-like symptoms, and study site. We excluded persons with missing information for independent variables (173 for day before illness, 237 for day 1, 247 for day 2, and 216 for day 3) in addition to those mentioned above. p<0.01 for work experience study period interaction term for day before illness; p<0.001 for work experience study period interaction term for days 1–3 of illness. #For the October 2019–March 2020 prepandemic influenza season when all participating sites collected data on work status and location of work on the day before illness onset, aOR for the day before illness = 0.35 (95% CI 0.22–0.57).
