We wouldn’t know. Our contact tracing stinks. The vast majority of cases are not linked to anything.Did they share the number of cases that are linked to indoor dining?
If you had to go by contact tracing, you would conclude that the disease spreads by magic.
There are good studies on restaurants/bars causing covid transmission, but they are on the statistical analysis level, not the individual case level. We can tell you that we are 99.9% certain that indoor dining raises covid rates, but we can’t tell you whether Bob got covid at McDonald’s.
