If this is any sign of what may happen across Europe or Canada, it doesn't look great. It looks like they are planning to try and reopen after a lockdown, but I would be surprised if that happens at the pace they are expecting.
As for the US, I doubt this would happen at a national level. Potentially some states, but even then, i have my reservations about political pressure, vs. doing what is likely the right thing to do.
