According to a recently published study in the Virology Journal, SARS-COV-2, the Coronavirus which causes the COVID-19 disease, can remain infectious on smooth surfaces for up to 28 days.
Titled “The Effect of Temperature on Persistence of SARS-COV-2 on Common Surfaces,” researchers at CSIRO, Australia’s apex scientific research agency, have claimed that SARS-COV-2 remains active for 28 days on banknotes, glass, and stainless steel at 20°C.
Conversely, the survival time of SARS-COV-2 decreases with the increase in temperature. For instance, the SARS-COV-2 can remain infectious on smooth surfaces for just 24 hours at 40°C.
During the study, CSIRO researchers dried SARS-COV-2 in an artificial mucus on various surfaces at concentrations similar to samples from COVID-19 patients and extracted the virus a month later.
In contrast, Influenza A virus, which is a flu virus, can stay infected on smooth surfaces for 17 days.
Chief Executive at CSIRO, Larry Marshall, has called on the masses to exercise frequent cleaning and handwashing to contain the spread of COVID-19.
Larry further said that CSIRO’s study will help in curbing the transmission of the deadly infection.
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.
Director at the Australian Centre for Disease Preparedness, Trevor Drew, has said that CSIRO’s research helps in understanding the persistence and transmission of SARS-COV-2 in cold areas.
