"Right now, there are about 1,800 survivors of the current West African outbreak, all of whom are now immune, of course. But there may be many thousands more."

Well, that's conjecture, oddly enough, reinfecting people with a deadly disease has various ethical issues - so there aren't any experiments to look at.

When it was tested with primates [1] they all survived after a 10 week period but 2 out of 6 died after 13 week period. How this works for humans god knows but 'all of whom are now immune' I wouldn't be so confident.
