Coronavirus can live on a smartphone screen for up to four days

According to researchers, the smartphone’s glass, if virus particles get on it, can remain a source of infection for 96 hours.

To protect against infection with the Chinese coronavirus COVID-19, doctors recommend washing their hands more often and avoiding contact with infected people. This will prevent the penetration of viral particles propagating by airborne droplets into the upper respiratory tract.

However, infection has another route of transmission. According to an immunologist from the University of Tennessee Rudra Channappanawar, quoted by Quartz, the virus can live without a host for several days - for example, on the surface where it got from the body of a sneezing or coughing person.

Scientists have access to viability assessments for the causative agent of SARS, a close relative of the current coronavirus. According to data collected during the 2002–2003 outbreak, virus particles can survive on plastic and steel for up to 72 hours, and on glass, up to 96 hours. Most likely, similar values ​​are characteristic for COVID-19.

This means that a particle of the coronavirus that hits the screen of the smartphone will remain active for four days at room temperature. From here, it can get on the finger of the owner of the gadget, and from there - into his mouth or nose. Given that people take a smartphone in their hands several hundred or even thousands of times a day and often touch their faces, this greatly increases the risk of spreading the virus.

To make your smartphone safe, it is enough from time to time to disinfect it with microfiber soaked in soapy water or alcohol.

According to previous estimates, the maximum period during which various coronaviruses can survive without hosts is 9 days. For comparison, measles virus can withstand outside the human body for only two hours.
