Australian study says coronavirus could stay alive for 28 days on glass, currency in cooler weather

A study by an Australian lab says the coronavirus may remain alive and infectious for weeks on glass, banknotes and other similar surfaces. The study conducted by scientists at the Australian Centre for Disease Preparedness suggests that the coronavirus can survive on smooth surfaces for 28 days. The smooth surfaces include glasses found on mobile screens, plastic banknotes, grab handles and rails. The virus can survive on such surfaces at room temperature.

Debbie Eagles, the deputy director of the centre, in an email informed that the results show that coronavirus can remain infectious on surfaces for long periods of time, reinforcing the need for good practices such as regular hand washing and cleaning surfaces. According to the study published in Virology Journal, the coronavirus can survive less than a day at 40 degrees Celsius on some surfaces. The findings add to evidence the coronavirus survives longer in cooler weather, making it harder to control in winter than summer. The research also helps to more accurately predict and mitigate the pandemic’s spread, the scientists said.

China had started decontaminating its paper currency before Covid-19 was declared a pandemic, suggesting concerns over transmission via paper banknotes existed at the time, the researchers said, noting that the U.S. and South Korea have also quarantined bank notes as a result of the pandemic.
