great article, and 5 of 7 authors are or were Stanford people, including the 3 first authors and the senior author, so I'd say it's a Stanford article.
I hope people are trying to understand better the reasons for the differences among MSAs in these data. For examples, grocery stores accounted for a relatively small but increasing percentage of new infections everywhere except for the Bay Area where they remained basically constant, and Philadelphia MSA where the percentage increased enormously -- why? Did the Bay Area restrict more tightly the numbers of people who could be in the store at once, or did we have greater penetration of grocery delivery services than other areas?
