Another word of caution regarding Ebola survivors: given the high case fatality rate, the exponential spread of the epidemic, and that it takes several months for survivors to clear all the virus out of their system, the ratio of sick patients to virus-free survivors is likely to be at least 20:1 or more.
These people are a very precious resource. But they are also human beings who have already gone through a tremendous ordeal, may have lingering health consequences, and likely have seen dozens of friends and family members die around them. And as Ellen already mentioned - everybody in the world is already planning how to best bleed them dry for their antibodies or how to put them to work in Ebola wards...
I think the focus really needs to be the other way around: how can we best support these survivors, get them in touch with family members, give them psychological support, and combat any stigma there may be around having had Ebola. Once we have that in place, we can offer them the opportunity to *volunteer* to help in the fight against Ebola, if they choose to do so.
