I live in California, and while many here don't seem to be taking much action, people will talk about it if I mention it. They are concerned but not doing much, apparently, at this time. But I am. I've ordered canned foods, water, flour, and stuff so that I won't have to go out grocery shopping. The way to avoid this virus is to "self-isolate." Avoid crowds, mainly. But also take precautions like wearing a mask if you do. This could be very serious.
BTW, I happened to watch a documentary on the so-called "Spanish Flu" virus that killed over 100 miiiion people worldwide about 100 years ago. It's called the Spanaish Flu because Spain was the only country to honestly report the number of cases and deaths. All the other countries, perhaps because they were trying to have a war, while Spain wasn't, did not report how serious it was. So, people thought it was really bad in Spain and called it the Spanish Flu, when in reality it was no worse in Spain than anywhere else. Anyway, I think it's better to be safe than sorry about this thing. If it was designed as a weapon, and there's some indication it was, it won't be easy to stop. Good luck to us all.
