What happens when you cut part of a network off?

Starting today, the entire country of Sierra Leone started a three-day lockdown. During this time no travel will be allowed across Sierra Leone’s borders. This lockdown will take the world travel network and sever off all the people in the country of Sierra Leone, cutting off all edges in or out of Sierra Leone. Doctors Without Borders argues that lockdowns do not actually stop travel and disease, though, it just pushes it underground.

If this lockdown is successful, it will help officials stop the spread of ebola. But parties including Doctors Without Borders question the efficacy. Is it actually possible to sever a whole country from the world travel network?
