Is this a serious concern? Yes.
Is the media making this a large epidemic then it currently is in the United States? Yes.
My personal belief is that people are becoming fearful when they don't need to be. This isn't Africa, we have far more resources, sanitation, and aid to contain and control potential *diseases*. Just like many past illnesses over the years we've had this will pass by and the media will soak it up for all it's worth. Not only is the media thriving from this, so are companies that manufacture PPE (personal protective equipment), the more the media causes people to be in fear, the more money people will spend from protective equipment.
There have always been diseases, viruses, and illnesses that pop up in the United States and foreign countries on a yearly basis, they are dealt with, vaccines are attempted to be made, and the media moves on to the next great story.
Again I believe this a serious illness, but I think the media is blowing out far out of proportion because it keeps people watching... more views = more $$$
EDIT: Also the CDC is doing their job by quarantining people in a preemptive manor to prevent any further spreading.
