Coronavirus isn't the only virus to be concerned with, Norovirus is a well known one that can spread through surfaces, which is why it can be so rampant on cruise ships -- and it can live for weeks on surfaces.

Yes, but microphobia is more annoying than most viruses, and keeping the immune system unprepared due to lack of exposure is potentially fatal, so perhaps they don't want to encourage those...

Got any non-paywalled sources handy?

Normally I'd link to archive.is, but they put everything behind a captcha wall, which I'm not keen to solve.

You can bypass the paywall with scripts disabled, but the key excerpts are:

>But the era of “hygiene theater” may have come to an unofficial end this week, when the C.D.C. updated its surface cleaning guidelines (https://www.cdc.gov/coronavirus/2019-ncov/community/disinfec...) and noted that the risk of contracting the virus from touching a contaminated surface was less than 1 in 10,000 (https://www.cdc.gov/coronavirus/2019-ncov/more/science-and-r...).

>“People can be affected with the virus that causes Covid-19 through contact with contaminated surfaces and objects,” Dr. Rochelle Walensky, the director of the C.D.C., said at a White House briefing on Monday. “However, evidence has demonstrated that the risk by this route of infection of transmission is actually low.”
