If those SARS numbers are in the same vein as what is true for COVID19, the only answer is a vaccine. Otherwise our current state of affairs is the new normal for the foreseeable future.
It's estimated that ~14% of common cold cases are caused by coronaviruses (HCoV-OC43, HCoV-229E, HCoV-NL63)... so although it seems particularly difficult, if we do manage to discover how to develop effective vaccines against Covid19, perhaps the silver lining is that vaccines against the related viruses responsible for a significant fraction of the common cold will be in reach.
In that case COVID19 will play out like the 1918 flu, it will hit in waves that only mass quarantine will help mitigate, until enough immunity is reached. Likely 18 months - 2 years.
