Given the information we have, what are reasonable actions to take either personally or for your business if you're not currently in a high risk region?
Personally, I've purchased water, canned food & bags of beans, supplements, medication, an air purifier and cleaning supplies. I'll be working from home if the virus hits where I live. I think I'm not prepared in the sense of what I would like if the virus truly hits where I live. I'm guessing you would want to isolate yourself from everyone. I can only theorize but I assume 6 months would be how long the disaster could last. An ideal situation would be living in the middle of nowhere with 6 months of supplies. Lastly, invest in things to keep your psych positive.
The same best practices always apply whether there is an outbreak or not. Prevent the spread of germs by washing your hands thoroughly and often, keep high traffic surfaces clean. For the current novel corona virus, avoid travel to the affected region and avoid contact with people who have recently traveled to the affected region. So far all cases have been people who have traveled to Wuhan or have had prolonged direct contact with someone who has (e.g. a spouse).
