I don't know, people were speaking pretty confidently yesterday about how we didn't need to worry because it's hard to transmit, CDC has it under control, blah blah blah. They sounded like press releases for the CDC, but not realistic in terms of what could actually happen.
Time will tell, but I think it wouldn't hurt anyone to stock up on food supplies and masks/wipes "just in case."
If that's "freaking out," so be it.
