Its possible that most of the new cases being reported are in Sierra Leone or Guinea, and that the outbreak in Monrovia has indeed burned itself out.
The real danger is still leakage to another location.
The current data show that Liberia (where Monrovia is located) is contributing about one third of the new cases.
Liberia has not burned out the Ebola virus. As a matter of fact, with a population of just over four (4) million, the Ebola virus has only infected about two tenths of one percent of its population. There are plenty of bodies available for the Ebola virus to infect. I do not expect the increase in the case count to taper off until a significantly larger number of cases have occurred.
