OK, I’ll bite.
The first issue is how it would get into the system. Because physical contact is limited, it would take an effort to get it into there.
Although, once in the prison system it would spread pretty quickly because in most general population prisons there is a lot of close contact.
In the higher level prisons, there is more seclusion so the chances of spreading is limited.
It would probably take a pretty good run at low and medium security prisons. It would be limited at the supermax prisons. Remember, the more limited the interaction with each other, the less impact Ebola will have.
It would also not sweep through the system. I would image that when it appears somewhere, they would shut down transfers in and out—so it would not move across the system from one prison to another.
