I'm in the minority of the world on this one, but then again the majority of people usually fall for hysteria rather than reason. She tested negative for the disease already, and has zero symptoms. She's probably sick of the all the hysteria that's not science based going around at sites like info wars or natural news not too mention the MSM, and is taken a stand against it. She should do just do it voluntarily, and realize it's not worth the trouble.
I've done a voluntary quarantine before when I had E coli ten years ago, and I had to stay on it until I had three negative test, three weeks in a row. It was really not that big of a deal, I had a small child at the time and didn't want to take a chance. Then again i had tested positive so that's different. Still not worth the trouble to make a fuss about it.
The thing is she tested negative, has no symptoms, and without symptoms, it's not contagious. A force quarantine on someone like her isn't going to accomplish shit, other than satisfy ebola hysteria and make people feel safe.
Slippery slope here, should the fed have the power to force quarantine people that have tested negative for diseases because of mass hysteria?
What it does is allow medical professionals to catch it, if she has it, without anyone else having a chance to catch it.
