Sure...but when the experts predict one thing about a very deadly disease and then they're wrong repeatedly. When people are told protections are in place...and they aren't. When we're told there is no way it can enter the US and it does. When contact had to be human to human physical contact....and the Spanish nurse apparently touched a glove and got it. What happens to the credibility of the experts and leaders? It significantly erodes. People aren't going to believe them and will then become afraid....and then start to worry about worse scenarios.
All of that is on top of fears that have been ginned up for years by these same people about infectious diseases coming out of Africa and Asia, and about infectious diseases mutating rapidly. Ebola was said to act so quickly as to not be a threat...but could potentially mutate into one we were told, especially if it became less deadly and/or more transmissible. Now it's all over the place and ACTING differently than other outbreaks. Why?
I'm sure people who want to attack the US have thought about using every infectious disease they can....including Ebola. It was on the DOD list wasn't it? That leads to fears of its use now. But Ebola was never thought to be realistic..too rapid and not weaponizable. I believe Marburg was their biggest fear, at least it was a couple of years ago when I talked to DOD.
