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.
I'm working for one of Australia's largest employers and it is becoming clear that we'll be heading down the same path as New Zealand in a few days (from governmental sources to our CEO). This is a complete lock-down except for critical essential services (grocery stores, pharmacies, doctors, etc.) for four weeks. My wife and son are in the middle of this now. Australian authorities are delaying it to try and lessen the panic and further strain on the food supply chain. We are currently stretched to the limit to try and supply the two largest grocery chains, Woolworths and Coles. If there is another run on the stores, the supply chain will break. Distribution centres are empty, store shelves are empty and suppliers cannot keep up with demand. Things are about to get much more serious for people here. I am just thankful that I'm working as part of the food supply chain, so my job and those of my staff are safe...and that we live and work in rural, low population areas.
