Don't you come in here with your fancy graphics and science. I saw Outbreak. As soon as ebola hit our shores, we guaranteed fully 90% of our population would become infected. Baseless paranoia will always triumph over logic or reason.
Isn't an R value theoretical and depends greatly on the environment and countermeasures? In Africa with little or no infrastructure to contain ebola, I'd guess the R value is much higher. In the US, I would expect a fairly low R value. The problem is, based on the R value of 2 from that graph, it would be similar to HEP C . There are more than 3 million people in the US with Hep c. With the mortality rate we're seeing of 50% (or whatever it is now), that would be a LOT of dead people.
It's certainly not time to panic, but a healthy respect for the danger and taking logical steps to contain the disease are a good thing.
