Barely 24 hours after WHO declared the Ebola outbreak over, a new case has been reported discovered in Sierra Leone.
It is not clear what the source of transmission is. The patient did not have Ebola before.
The way Ebola keeps reappearing in different places after long periods of absence strongly suggests the notion that it is being introduced deliberately by an external source. That is, the cases are more consistent with an act of bioterrorism than with an epidemic.
