Background: New research by the Australian National Science Agency shows that the virus that causes COVID-19 can stay on daily surfaces for up to four weeks

CSIRO found that SARS-CoV-2 can survive at least 28 days on stainless steel, vinyl, plastic banknotes and glass at 20 degrees Celsius (about room temperature), such as those found on mobile phone screens.


It can stay on cotton for less than 16 hours at 40 degrees Celsius and up to two weeks at 20 degrees Celsius.


Australian scientists found that the lower the temperature, the longer the virus will survive on the surface.


SARS-CoV-2 tends to survive longer on non-porous or smooth surfaces, rather than porous surfaces like cotton.


According to research published in the Journal of Virology, the survival time on paper money is also longer than that on plastic paper money.

The virus lasts 10 days longer than the flu on some surfaces.


CSIRO CEO Dr. Larry Marshall said that determining how long the virus will survive on the surface allows scientists to more accurately predict and prevent its spread, thereby protecting communities from infection.


Dr. Marshall said: 'We hope this set of scientific solutions can break the barriers between us and shift our focus to dealing with specific virus hot spots so that we can get the economy back on track.


ACDP Deputy Director, Dr. Debbie Eagles, said the findings reinforce the need for good practices such as regular hand washing and surface cleaning.

At 20 degrees Celsius (approximately room temperature), we found that the virus was very strong and survived for 28 days on smooth surfaces such as glass on mobile phone screens.


A similar influenza A experiment found that it survived on the surface for 17 days.

The study involved drying the virus in artificial droplets on different surfaces at a concentration similar to that reported in samples from infected patients, and then re-isolating the virus within a month.


Further experiments were conducted at 30 degrees Celsius and 40 degrees Celsius, and the survival time of the SARS-CoV-2 virus shortened as the temperature increased.


Dr. Eagles said: 'Although the exact role of surface transmission, the extent of surface contact and the amount of virus required for infection have not yet been determined, determining how long this virus will survive on surfaces is critical to developing risk mitigation strategies in high-contact areas.


ACDP director Professor Trevor Drew said that this study may help explain the apparent persistence and spread of SARS-CoV-2 in cool environments such as meat processing facilities, and how to better solve these problems.


The study was conducted at the Australian Centre for Disease Prevention in Geelong.
