You still did not answer my question;<quoted text> Viral fee cows exist, but does virus exist free of cows...no except your diseased notion .
It's apparent your eradication will be the benefit of all who are truly alive.
A host is a host same species or not .... however, again just extending the thought experiment ... if we do manage to use cows as surrogate mothers, are the offspring alive? Are the genetic parents alive? Seems to me that we would be very close to viral reproduction at that point!
