A team of German researchers published a study in the Journal of Hospital Infection where they assessed data from 22 studies on human coronaviruses such as Severe Acute Respiratory Syndrome (SARS) coronavirus, Middle East Respiratory Syndrome (MERS) coronavirus, and endemic human coronaviruses (HCoV). They discovered that the coronavirus can also live on inanimate surfaces like metal, glass, or plastic, for up to nine days. They discovered that, "although the viral load of coronaviruses on inanimate surfaces is not known during an outbreak situation it seems plausible to reduce the viral load on surfaces by disinfection, especially of frequently touched surfaces in the immediate patient."
So it's time to be extra careful with your gadget. An effect cleaning solution involves 0.1% sodium hypochlorite or 62 to 71% ethanol. Either of these "significantly reduces coronavirus infectivity on surfaces within 1 min exposure time. We expect a similar effect against the SARS-CoV-2." (SARS-CoV-2 is the virus that causes COVID-19, according to the CDC.)
"You do not have to sneeze on a cell phone to transmit disease-causing organisms," says Charles Gerba, Ph.D., professor of microbiology and immunology at The University of Arizona. "What we found out in studying virus movement on surfaces in office buildings is that you touch a surface with a virus on it and then you place it on your cell phone." (A door handle, for example.)
"You then go home or to another location and you touch your phone again and, says, touch a table moving it to another location—great way to spread viruses around an office."
Gerba recommends an "alcohol wipe or a microfiber cloth."
"I would do it every time I have been out in public," he says.
