MELBOURNE (Reuters) – 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, Australian researchers said on Monday, highlighting the need for cleaning and handwashing to combat the virus.
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. The study was published in Virology Journal.
By comparison, Influenza A virus has been found to survive on surfaces for 17 days.
CSIRO’s research involved drying virus in an 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
