It's certainly possible. What we don't know about this virus could fill volumes.
A lot of "hot" epidemics burn themselves out fairly quickly. Otherwise, we'd probably all be dead of ebola by now. That may be the case with this.
But the evidence is contradictory, and the government reactions are contradictory. I don't think we know, and I don't think they know, either.
What I'd like to know is whether anyone gets well without hospitalization. There aren't 30 million hospital beds in this country.
