Hospital officials are not sounding the alarm, however.
The virus that causes COVID-19 can stay active on smooth surfaces like smartphones, metal surfaces and paper money for much longer than the flu virus, according to researchers from Australia’s national science agency. They found that it can remain viable for up to 28 days, albeit in a very controlled environment. Under the same conditions, the influenza virus remains infectious for just 17 days, according to the study.
The team said the research proves that the coronavirus is “extremely robust” compared to other viruses. “These findings demonstrate SARS-CoV-2 can remain infectious for significantly longer time periods than generally considered possible,” the study concludes. (Cloth and other porous surfaces can carry infectious virus for just half the time, or around 14 days.)
While it shows the importance of cleaning and disinfecting phones and other surfaces, the study comes with some large caveats. It was conducted at a constant 68 degree F
