City lockdowns

San Francisco has just issued a city wide lockdown for three weeks. The mayor is following Italy’s lead, and people are only being allowed to leave their homes to go to the doctor or grocery store. Do you think other places will follow suit? I know where I live—we’ve had two confirmed cases—restaurants are starting to close their seating areas and it’s drive thru only. Even Starbucks has enacted this. Do you think the country as a whole will end up quarantined to their homes before this is over?
