Coronavirus. I provide links in this posting to get information on this illness that you can trust. DO NOT PANIC. We see signs and memes all the time having fun with this phrase, but there are times when it is very good advice. This is one of those times while an epidemic of a dangerous coronavirus illness is spreading in mainland China and starting to appear in other countries. My best wishes and thank you to the Chinese mainland for throwing resources to reduce transmission and to treat the ill. The situation seems bad, but imagine what it would be like without the existence of our own U.S. Center for Disease Control (the CDC), or the World Health Organization (spawned from the United Nations). Imagine if we did not understand even what viruses were or how they work. It would be like the middle ages as plague spread and humans were oblivious about how to stop it, what it was, and even continuing to behave in ways that helped it spread more. I say, Do Not Panic. Why should we not panic now?
