Ebola: how long after exposure before you test positive?

Factual Questions
1

The latest news is that Kaci Hickox is refusing home quarantine.

The article mentions that “she has twice tested negative for the virus.”

I’m somewhat puzzled by the relevance of those tests. Assuming she could possibly have been exposed as recently as the day she left west Africa, and assuming that she was indeed infected as a result of that exposure, how long after that would she continue to test negative for the virus?

If testing negative means you are not infectious, wouldn’t it be cheaper and/or less burdensome to just test someone like Hickox on a daily basis for 21 days, instead of making her stay at home (or forcing her into an expensive, fully staffed quarantine facility)?

This is discussed in superb detail, with updates almost daily from the med literature by people who know, in the current thread

Using any test possible, when is the earliest that Ebola can be detected in vivo?

Machine, I’ve asked the mods to close this thread and send people off to there, so info can be centralized.
