What to Do? What to Do?

The Ebola outbreak is kind of freaking me out. It's scary that the guy in Dallas was initially sent home from the hospital and came into contact with so many people before he was finally quarantined. I don't know what can be done to try and stop the spread of this disease throughout the country and throughout the world. I would hate to see entire communities of people quarantined but how else can the spread of disease be contained?
