If anyone can remember, I said that the Corona viruses can survive a long time on surfaces -depending on the relative humidity and the temperature. Wrote at that time that on currency notes it will survive for two days and there are recorded instances where SARS remained active for 28 days on surfaces with 4 deg C temperature.
Here is a latest by CDC......on Corona viruses
New Study Indicates How Long Coronaviruses Can Survive on a Surface
If the new coronavirus 2019-nCoV (now also called COVID-19 virus) is anything like its family members, a new study suggests it could survive on inanimate objects for well over a week.
According to the United States Centers for Disease Control and Prevention (CDC) it's "currently unclear if a person can get 2019-nCoV by touching a surface or object that has the virus on it and then touching their own mouth, nose, or possibly their eyes."
In fact, not a lot is known about the COVID-19 virus at all, so researchers are turning to similar coronaviruses, like SARS and MERS, for answers.
Reviewing the literature on all available human and veterinary viruses within this family, encompassing 22 studies, researchers have found that the human pathogens can persist on surfaces and remain infectious at room temperature for up to nine days. (To put that in perspective, the measles virus can live on contaminated surfaces for up to two hours.)
Granted, that's the upper end of a coronavirus lifespan, but on average, researchers say this family of viruses can survive between four and five days on various materials like aluminium, wood, paper, plastic and glass.
Some of the veterinary coronaviruses - the ones that can only infect animals - could even persist for longer than 28 days.
"Low temperature and high air humidity further increase their lifespan"
