Can we change the title of this thread to something like "Coronavirus Thread"?
A few years ago, when those tiny few Ebola cases in the U.S. happened (and the patients were sent to, of all places,
Omaha), I had a brief discussion about it with a co-worker. All the news about Ebola was scaring him, and I was not even the tiniest bit concerned. I told him the reason was, the symptoms of Ebola are so scary that it makes the transmission of it in a developed country very difficult. Basically, you know exactly who is contagious because they are bleeding out of every pore.
This Coronavirus has me concerned. It is just the opposite of Ebola : a person can be contagious before showing symptoms. There could be dozens of people in the U.S. already, transmitting it to others, and we wouldn't know it.
