Everyone seems to worried about catching Ebola. They come up with ever more fanciful ways for it to be transmitted, despite the fact that the data suggests that the contact has to be either very significant or very late in the disease's progress for someone to be infected.

Well, maybe anecdotal evidence will help, since data doesn't seem to have an effect. Thomas Eric Duncan, the index case, who flew from Liberia to the United States did not infect anyone before he went into the hospital. No one.

1. He infected no one on the planes he flew.

2. He infected no one in the apartment complex where he lived.

3. He didn't even infect his fiancee or his nephews.

The woman who went on the cruise (admittedly she had no contact with Duncan at all and was a very unlikely candidate for infection in the first place) - no Ebola.

African countries freed of Ebola; monitoring period over for 48 Texans

I'm not saying Ebola isn't a dangerous disease. It is very dangerous, although less so in places where you can get high quality medical treatment. I'm not saying Ebola isn't infectious. It is, but really mostly at the latest stages of infection.

In developed countries, the people with significant risk are health care workers, because they are treating patients when they are most infectious. The more we can do to protect those people, the better. That is where we need to put our resources and where we should concentrate our concern.

While I am unconvinced of the value that the TSA provides, the one thing I am not worried about when it comes to the TSA, it is catching Ebola.
