In the wake of this morning’s news about a second Ebola patient in Dallas, Democratic hack Donna Brazile is still in “don’t worry, be happy” mode.

MSNBC host Joe Scarborough, on the other hand, serves up this useful reminder:

Ebola survivor Nancy Writebol also doesn’t know how she got the virus:

I don’t know how I became infected and how I contracted it. There are some thoughts about how I might have gotten it. Nobody is really sure, least of all me. I never felt like I was unsafe and I never felt like I walked into a situation where I was being exposed. I was on the low-risk side of things. I never was in the crisis or the Ebola center. I was always on the outside. I made sure doctors and nurses were dressed properly before they went in, and I decontaminated them before they went out. We kept a close check on each other about whether people felt safe.

We had an employee who was doing the same job that I was doing. He got sick and I didn’t know he was sick. He didn’t tell anybody. He actually thought he had typhoid. The day that I started having symptoms, at least a fever, was the last day I saw him. He did have Ebola. He did not survive.

I never remember touching him, although it’s possible he could have picked up a sprayer to decontaminate someone, and I could have picked up the sprayer. Or we touched the same thing. I never touched him.
