Sometimes, the virus mutation actually works to our advantage, if it weakens the protein function. In addition to the effective measures taken by public health agencies (including that evil WHO!), it is speculated that SARS-CoV-1 disappeared by basically mutating itself into extinction.
I read a few articles on CoV-1 and haven't seen any mention of mutation. Most say reason for it being contained was that it was mainly transmitted by people who were sick, and those people got very sick, very quickly so could easily be identified and isolated.
