Not to be a fear monger, but, all of these measure are the best we can possibly hope for, but, in the end, a lot of people...a lot...will get sick despite. But you gotta do what you can. It's so mind boggling that such a tiny creature could wreck such havoc (think Black Plague, etc). Bottom line: keep yourself as healthy as possible, avoid large crowds, hand washing, etc. I've been out of school all week myself. Going to the doctor is like crazy. Everyone in masks (as you'd expect). Signs on the door "We don't test for C-19 here" etc. I coughed in the waiting room and everyone glared at me! This will certainly expose how ill equipped we are for such a problem, but, just how ready can one be. I pray for all esp the elderly and others with compromised health at this time.
Ps...just being over 60 puts one in the 'high risk zone'...that's me, and alot of us I'll bet...
