If you haven't prepared yet, I highly recommend you do so as soon as possible. Consider that there could be an extended lockdown and you wont be able to get out. The quarantine is the only measure they know how to take. Just think of what you would need if there was a quarantine that lasted longer than a few weeks.
Italy is now on lockdown. Cases in South Korea are becoming exponential. One report says infected persons has risen above 600, this is not confirmed. Other sources say 4 and 500. The infected areas in Korea are also on quarantine.
A few hours ago I was looking on Walmart online to order some more beans, they were in stock a few hours ago. I decided to make my purchase but they were already out of stock. If you don't make your purchases now, the food might not be available later. This could get serious.
I am not trying to be alarming, but just saying we should be prepared just in case. We can't be sure what will happen.
