A new research by Australia’s National Science Agency revealed that the SARS-CoV-2, the virus responsible for COVID19, can survive on smooth surfaces like glass, currency notes and stainless steel for 28 days.

However, the findings of this study were made in lab conditions and not real-life situations. For the experiment, the virus was dried in an artificial mucus and placed on a range of surfaces, like samples collected from infected patients. This was extracted after a month for review.

The tests, carried out at 20, 30 and 40 degrees Celsius, displayed that the contagion was extremely vigorous at 20 degrees. As the temperature increased, its survival time seemed to decline with its intensity dropping over a period of time. Also, the entire examination was done in the dark as past research shows that direct sunlight may kill the disease.

Citing that Coronavirus remains infectious for much longer than other flu viruses, the scientists said that a virus like the Influenza A survives on surfaces for around 17 days. They further maintained that the COVID infection spreads through air largely.

As the authors of this investigation continue to look for more details about the novel Coronavirus, they still recommend that frequent and proper washing of hands and sanitisation can protect one from becoming COVID19 positive.
