Australian Research: Coronavirus can survive 28 days on glass, currency
Australian researchers said that COVID-19 can survive on banknotes, glass and stainless steel for up to 28 days, much longer than the flu virus, highlighting the need for cleaning and washing hands to combat the virus.
The study published in the Virology Journal states that Researchers at Australia's national science agency, CSIRO, found that at 20 degrees Celsius (68 degrees Fahrenheit) the SARS-COV-2 virus remained infectious for 28 days on smooth surfaces such as plastic banknotes and glass found on mobile phone screens. By comparison, Influenza virus has been found to survive on surfaces for 17 days.

CSIRO's research involved drying virus in artificial mucus on a range of surfaces at concentrations similar to samples from COVID-19 patients and then extracting the virus after a month.
Experiments done in controlled laboratory environments at 20, 30 and 40 degrees C showed that the survival time declined as the temperature increased.

CSIRO Chief Executive Larry Marshall said, "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,"
Proteins and fats in body fluids can also sharply increase virus survival times.

"The research may also help to explain the apparent persistence and spread of SARS-CoV-2 in cool environments with high lipid or protein contamination, such as meat processing facilities, and how we might better address that risk," said Trevor Drew, director of the CSIRO’s Australian Centre for Disease Preparedness.
Australia has fared much better than most other rich nations in combating COVID-19, with a total of about 27,000 infections and 898 deaths in a population of 25 million.
