Found the Times piece. It was a letter, not an article.
From - Professor Emeritus Ronald Eccles, former director (1988-2017) of the Common Cold Centre Cardiff University.
You are completely correct to report that touching door handles probably will not infect you with Covid-19 (News, last week). Nearly all studies on the virus survival use culture medium, which is a friendly environment for viruses, but viruses are transmitted in respiratory mucus, which is a hostile environment as it contains antibodies and peroxidase.
This point has clearly not got through - as you indicate, hospitals, companies and public agencies spend billions of pounds on deep cleaning. I have been contacted numerous times by large organisations asking if the should clean all commonly touched surfaces in offices every night to prevent the spread of colds.
My reply has been that these surfaces will clear themselves of infectious viruses overnight - without cleaning.
