COVID-19 Outbreak (Update: More than 2.9M cases and 132,313 deaths in US)

I'm not sure what the situation is in the US, but Australian states are closing borders and requiring anybody undertaking cross-border travel to self-isolate for 14 days when arriving from within the country (previously self-isolation requirements only applied to those returning from overseas or where there has been exposure to a confirmed case).

I think that's the most effective way to make people stay where they are without welding them in their house ala Wuhan.

The US is nowhere near that - in part because there is no federal interest in that. Individual states could be attempt more stringent lockdowns and border closings but it would be very challenging without federal assistance.

The federal position at this point is “this is as much as we’re willing to do and we’re starting to lose patience.” And they don’t support new economy-blunting measures, no matter the epidemiology behind them.
