From the press conference.
Test conducted at the Houston lab, but sent to the CDC for verification

Beyond that, the woman from Ft. Bend just read the talking points about what to do and not to do that we've all heard a million times and that was it.
From the Houston lab director:
They began running tests today, and this result was the only positive one. Tomorrow will be the first full day of tests as they're submitted, but they will still have to be prioritized. They will not test someone quickly if they have no symptoms, travel history, or no known contact with an infected person. (In other words, you're not going to get tested just because you want to be.)
One thing they pushed a lot is if you are sick with any kind of respiratory virus, you need to stay home.
They won't say how many people this person came into contact with ("we're still investigating") nor will they say where he traveled to. They did say he does not have any preexisting conditions. They will not say where the person lives nor which hospital he is in. They would not say what airline he flew or which airport he flew into.
Edit: One thing I did gather from their comments. It sounds like the guy used his brain and didn't just roam around while sick. He contacted his doctor who probably figured out the guy could have the Kung Flu and the process went from there.
"If you will not fight for right when you can easily win without blood shed; if you will not fight when your victory is sure and not too costly; you may come to the moment when you will have to fight with all the odds against you and only a precarious chance of survival. There may even be a worse case. You may have to fight when there is no hope of victory, because it is better to perish than to live as slaves." - Sir Winston Churchill
