10 minutes? Professor Chris Whitty* told MPs this morning "It's probably largely gone
by 48 hours and almost completely gone by 72 hours on a hard surface." But I suppose
to some people he's just another bloke on the internet - and old and white to boot.

I was thinking more on these lines -

Alison Carey, MD, an associate professor of microbiology and immunology
at Drexel University, tells Health. "Flu viruses can survive on hard surfaces
(like bus poles) and infect another person for 24 to 48 hours,"

However

The longer the virus sits, the more the possibility of someone catching
the cold or flu decreases, Dr. Carey says. "But people can definitely
get it from touching bus poles, especially in the five to 10 minutes that
elapse from a sick person getting off the bus and someone else getting on,"
she says.

She's white as well, although at a guess, not trying so hard to cover her arse


Well found. Pity:

a. you didn't post that in the first place rather than an unqualified
"up to ten minutes"; and

b. you didn't check what health.com said. Follow their link to Alison
Carey and you'll see she is in the Department of Paediatrics
specialising in the neonatal immune system. Forgive me for thinking she
us rather less well up on coronaviruses than the NHS, CDC, et al. I
looked as I couldn't fathom why a specialist would refer to flu when
there is work on coronaviruses where work on SARS and MERS has given
evidence. Eg

"Persistence of coronaviruses on inanimate surfaces and their
inactivation with biocidal agents"

https://www.journalofhospitalinfection.com/article/S0195-6701(20)30046-3/fulltext

Too long/CBA? Try

"Human coronaviruses can remain infectious on inanimate surfaces for up
to 9 days. Surface disinfection with 0.1% sodium hypochlorite or 62€“71%
ethanol significantly reduces coronavirus infectivity on surfaces within
1 min exposure time."
