Since July 27th, 12 people have been tested for the possible Ebola virus in the United States, those test came back with no Ebola..
Well now it seems that there has been one confirmed in Dallas, TX.. This is the first diagnosed case in the United States.. The Patient has been in strict isolation even before they confirmed it, simply to keep the risk of spreading to the most minimum point possible.
There is a press conference hosted by the CDC at some point today, potentially going on right now as I'm posting this.. so when it gets uploaded I'll post it here.
