It all depends on how well people decide to follow the rules of quarantine.
I think you can assume that most will not..
They tried to quarantine the slum in Monrovia...approximately 50K people....they had to lift it because of the violence..
One think I noted while looking at the map. The state of Liberia has little population other than Monrovia...very few villages of any size other than the capital.
It would be easy to quarantine it, if one needed to.The geography makes it doable....just sayin..
