A member asked:

How come virus can mutate so fast?

A doctor has provided 1 answer
Dr. Ed Friedlander answered

RNA-based: The RNA-based viruses have a mutation rate 100,000x faster than DNA viruses just because the molecule is less stable. Viruses also replicate much more rapidly regardless of their nucleic acid.
