Is community spread of zero a worthwhile goal? SF still has thousands of people (maybe tens of thousands) coming in and out of the city every day to deliver things, see family, return home, etc. As long as this is still happening (there is no way for SF to prevent this) what is the point of fixating on zero new cases.
Consider two cases:
- On May 15 SF has had no new cases since May 1st. It decides to reopen.
- On May 15 SF has had 150 new cases (ten a day) since May 1st. It decides to reopen.
By June 15th, is the total number of cases any different under these scenarios? In either case, has the city been able to function without having to reclose?
I'm not sure the answer to these - but my instinct is that the situations would be virtually the same.
