* Identified through expanded contact tracing. The 20 high-risk contacts were from 12 clubs.

^† If information about the specific interaction was unknown, person was excluded.

^§ Two of the eight household high-risk contacts worked and lived with the index person with COVID-19 and likely also had work environment interactions but are excluded from that analysis because of the high-risk level of household exposures.

^¶ Based on KINEXON device data and interviews (n = 4) or interviews only (n = 8). Multiple interactions are possible.

**Unknown for two of four.

^†† Three of the four were exposed in a team hotel; one of the four was exposed in an NFL club facility.

^§§ Five of the eight were exposed at a party/social gathering, one of the eight in a restaurant, and two of the eight in a car.
