How many mutants are out there now ?

There are now 6 strains of sars out there as on yesterday IIRC

the SARS coronavirus is undergoing rapid evolution in our population

This is entirely typical coronavirus biology. That's why there are hundreds (or more) cold viruses, and that's why there is no cold vaccine.

If the SARS coronavirus acts like other coronaviruses, it will spread rapidly, become endemic, and change constantly.

An excellent post. Thanks.

RNA mutations do not often work in favor of of the virus. A mutation can make it deadlier or less deadly. Whatever flaws exist in the genetic makeup of the virus are always replicated through each mutation, so as new flaws appear, they are passed on to the next generation of the virus. That would seem to work in our favor most of the time. However, the dice could roll snake eyes. The Spanish Lady was more deadly in the second round.
