Findings from the Australian National Science Agency suggest that SARS-CoV-2 may survive on surfaces longer than previously thought.
The virus is most often spread by coughing, sneezing, and talking.
But experts say that airborne particles can also spread through surfaces like metal or plastic.
Previous laboratory studies have found that SARS-CoV-2 can survive two to three days on banknotes and glass and up to six days on plastic and stainless steel, although results vary.
But the latest study by the Australian Agency CSIRO found the virus to be “very strong”, surviving 28 days on fine surfaces such as glass on the phone screen, but also on plastic and paper banknotes, when kept at 20 degrees Celsius. . , which is room temperature.
By comparison, live flu can survive under the same circumstances for 17 days.
The experiments were done in the dark, because it turned out that ultraviolet rays kill the virus.
