If a virus has a high mutation rate it can overcome our immune memory by changing its' surface proteins (Ag's) so the antibodies that are produced no longer attach. The RNA viruses are good at this.

Sometimes during the process of copying the RNA or DNA of the virus, small errors (substitutions in nucleotide base pairs) occur in the copy. These errors are replicated into subsequent copies. If the change isn't fatal to the virus and causes it to stop replicating, then the virus has resulted in a mutation.

Furthermore, it may be assumed that airborne transmission is the best possible trait for the virus, as a mutation of this degree would ensure its continued evolution and progression.
