Covid-19 remains infectious on some surfaces for 28 days, according to new study

The virus that causes Covid-19 can survive on banknotes, glass and stainless steel for up to 28 days, much longer than the flu virus, according to a new study.

Researchers at Australia’s national science agency, CSIRO, found that the Sars-Cov-2 virus remained infectious for 28 days on smooth surfaces such as plastic banknotes and glass found on mobile phone screens.

In comparison, Influenza A virus has been found to survive on surfaces for 17 days.

“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,” CSIRO chief executive Larry Marshall said.
