Therefore it is probably only likely to contain such genetic
information if it was fairly recent in origin or use as it doesn't
really have the room, being a virus, to carry too much 'spare'
The only point that I was trying to make was that you cannot predict
with 100% accuracy that Ebola is going to become airborne in the
