gotta run the gauntlet. Airport entrance, ticket agent, boarding gate, stewardesses, customs in US - were you in Lombardy, any contact, taking any meds, did you just cough etc. - if you can find a flight at all.
So far we’ve got about 9700 travelers from wherever, quarantined at ports of entry in Calif. I think NY just said they have about 3K. Each of the 11 ports of entry probably have a few thousand quarantined each. If they’re foreign nationals from hotspots that quarantine is mandatory 14 days and double testing before release the way I understand it. Enough in itself to stop many non-citizen tourists. Citizens get to home quarantine, tho, if they’re symptom free
