By way of real life example, if this homeless man was NOT infected while he was in the ambulance (which won’t be known until after the end of the incubation period) He can still come down with Ebola?

At least that’s what you said in post 14.

I don’t understand how that part of Ebola works.

Authorities in Dallas are trying to locate a homeless person who might have had contact with the lone Ebola patient diagnosed in the U.S. http://www.freerepublic.com/focus/f-news/3211612/posts

In post 14 I said "The main risk group like the step daughter, Youngor, are in day 7 of hypothetical incubation. They are over the hump, so each day from now that they do not present symptoms they have a lower risk of getting Ebola. Youngor went to the house on Sunday, fed the victim, took his temp and BP, sat him up in bed etc. So she is the highest risk person to be looking at plus her family."

That was not well written. I should have talked about the homeless guy, not Youngor and other direct contacts. The case of the homeless guy is simple, he either got infected in the ambulance or he did not. If he did get infected, we have to wait 21 days following last Sunday to find out for sure and be able to rule out that case. If he did not get infected, we still have to wait because we don't know if he got infected or not.

Once that incubation period is over (2 to21 days) he will either come down with the full blown disease with all the symptoms or nothing because he either did not get infected or his immune system successfully fought it off.

There's only one other possibility that could complicate the case of the homeless guy. He could have transferred some virus on his clothes and then transferred it to someone else later including himself. So there could be an infection later than last Sunday.
