Whereas the two North American isolates differ in only eight nucleotides, a broader comparison across the 10 genomes now available shows much more variation. Although some variations may be due to sequencing errors, the data do suggest that the virus is mutating quite rapidly, says coronavirologist Luís Enjuanes of the Autonomous University of Madrid; variations occur both in the enzymes that help it replicate and the proteins that sit on its outer surface. That could mean the virus will prove adept at eluding drugs and vaccines, Enjuanes warns.

It's like chasing shadows... once a magic bullet may be developed, chances are the critter will have mutated, rendering the magic bullet useless.
