sorry.
that's hundreds of thousands in state-ordered quarantines due to having tested positive. these people should all be inside.
....plus hundreds of thousands or potentially millions more in self-imposed quarantine because they're experiencing mild symptoms.
so, setting up at a grocery store among people that feel well enough to not quarantine is excluding all of the people that are quarantining.
i'm more awake now, let me see if i can find the actual study.
