Ebola

There's no reason to freak out over Ebola. It's hard to catch, hard to spread. A good list of 15 things to know about it is here. Or you can take the test below:

 Let's look at how attitudes about Ebola in the U.S. have changed. Warning -- some of these are different questions, so compare at risk.

August 2014: A Harvard School of Health poll had 59 percent "not concerned" about an outbreak in the U.S. One-third said Ebola was spread "very easily" and another third said "somewhat easily."

September 2014: A CNN poll  had 34 percent "not too worried" and 39 percent "not worried at all" about contracting the disease.

So not a lot of change. Yet.
