Covid19 Virus can last 4 weeks on surfaces: Scientists have found that the virus is “extremely robust” at 20c (68F) which is room temperature. However, it becomes weaker and survives for less time in hotter temperatures. The research, carried out by Australia’s national science agency (CSIRO) involved drying the virus in an artificial mucus on different types of surfaces. Using the same concentration of the virus that appears in infected patients and then putting it into isolation again for a month.

As direct sunlight can rapidly de-activate the virus the tests were carried out in the dark. Deputy director of the Australian Centre for Disease Preparedness, Dr Debbie Eagles, said. “Our results show that SARS-CoV-2 can remain infectious on surfaces for long periods of time. Reinforcing the need for good practices such as regular hand washing and cleaning surfaces.

At 20 degrees Celsius, which is about room temperature, we found that the virus was extremely robust. Surviving for 28 days on smooth surfaces such as glass found on mobile phone screens and plastic banknotes. For context, similar experiments for Influenza A have found that it survived on surfaces for 17 days. Which highlights just how resilient SARS-CoV-2 is.” The findings from the study show us that the virus is capable of living longer on smooth surfaces. Such as vinyl, glass and stainless steel but is less likely to survive on porous surfaces like cotton clothing.
