If it's uncontrollable were looking at a large reduction in the human population. ~50-70% going by the mortality rate.
However it could be much more controllable in a country like ours due to the majority not believing western medicine created ebola. We also have much better medical equipment and staff so the mortality rate could be much lower.
On the flip side if too many people catch it the NHS will be overrun and run out of beds. Staff will become sick through lack of training/kit so less people to treat the infected. Also just because we're not mistrusting of western medicine doesn't mean the majority aren't thick and as such would help to spread the virus through panic or fear.
Who realistically knows
