Message: <blockquote data-quote="imhotep" data-source="post: 25980344" data-attributes="member: 562115">Mutations arise naturally as the virus replicates.  It's a natural process. Some of these mutations do not propagate and die off, and rarely a very small minority are likely to be important and to change the virus in an appreciable way.  There are more than 4000 minor mutations noticed in the Spike protein itself already. The positive side is that these mutations can be used as tracers to point the parent infection and to monitor outbreaks.As I have previously mentioned some of these mutations can be beneficial.  This is exactly what took place with the SARS virus. There was a major change with 29 nucleotide deletions that happened by chance in the ORF8 region. This made the virus more virulent but luckily it also lost the ability to infect humans like before. It became part debilitated.</blockquote>
