Three of the four members of family B were infected, and two of the seven members of family C were infected. Five members of family A were also infected, including the index patient. The two patrons at TC who sat the closest to TA were not infected, nor were any patrons at the remote neighboring tables, but the patrons at neighboring tables had a higher infection probability than patrons at remote tables (X 2 =16.08, P<0.001, chi-squared test with continuity correction, Table 1 ). The infection risk was also higher for patrons at zone ABC tables than those at non-ABC zone tables (X 2 =25.78, P<0.001, chi-squared test with continuity correction, Table 1 ). None of the patrons seated in the non-ABC zone were infected. the author/funder, who has granted medRxiv a license to display the preprint in perpetuity.
