Researchers find SARS-Cov-2 survives on glass, paper and stainless steel for longer than thought.
"Establishing how long the virus really remains viable on surfaces enables us to more accurately predict and mitigate its spread, and do a better job of protecting our people," said CSIRO chief executive Dr Larry Marshall.
Previous studies have assessed its survivability on stainless steel and their results have varied wildly, ranging from between three and 14 days at room temperature. The new study looked at how long the virus could survive on glass, paper and plastic notes as well as steel. They found that they could detect it after 28 days on all these surfaces at 20C - significantly longer than the earlier studies had indicated.
The study's authors said the ability of SARS-Cov-2 to persist on stainless steel at cooler temperatures could explain outbreaks of Covid-19 at meat processing and cold storage facilities.
