Researchers find Sars-CoV-2 survives longer at lower temperatures and lasts 10 days longer than influenza on some surfaces
Australian scientists have found that the virus that causes Covid-19 can survive for up to 28 days on surfaces such as the glass on mobile phones, stainless steel, vinyl and paper banknotes.
The national science agency, the CSIRO, said the research undertaken at the Australian Centre for Disease Preparedness (ACDP) in Geelong also found that Sars-CoV-2 survived longer at lower temperatures.
It said in a statement the virus survived longer on paper banknotes than on plastic banknotes and lasted longer on smooth surfaces rather than porous surfaces such as cotton.
However, the experiment was done in a dark area which negates the effects of UV light. Peter Collignon, a professor of infectious diseases at the Australian National University, said this is known to reduce the life of the virus on surfaces.
“It is a factor, and that’s why the outside is probably again safer than inside because UV light is there and the virus can be inactivated on playgrounds and things in the sunshine,” he said.
There is also significant uncertainty about exactly how large surfaces play into the transmission of the virus.
