I was wondering about that.
It would seem to me that maintaining a strong immune system would reduce our risk, at least to some degree. But from what I’ve seen nobody has even tried to address that.
Not as far as we know now. Ebola is a virus and as far as we know the immune system provides no protection at all. But there is little research to say that this is right ot wrong. For now, untested evidence is that immune system does not resist Ebola virus.
