My late father-in-law used to say, "For every one thing the doctors know, there's 10 things they don't." It's a frighteningly true statement.
If there was an outbreak here, I can assure you that my kids would be home from school, I'd be working from home and my wife (who works in the health care industry) would either be home with us, or staying somewhere else until the scare was over.
I wouldn't put my kids at risk for anything. The wife can make her own choices where she's concerned.
P.S. My daughter has an incredible tolerance for pain. She's hit 105 degrees once and 104 degrees twice in her 3 short years. That alone is very scary. That's the only way we ever know if she's sick or not. I say this because I don't like seeing my kids sick, let alone sick with something they know nothing about.
