Recently, a study done by Australian researchers has shown that novel coronavirus can remain infectious on surfaces such as currency notes, phone screens, and stainless steel for 28 days.

Dr. Faheem Younus has called the study published in Virology Journal, "nonsense" and inaccurate. The Twitter-famed doctor who has acquired quite a social media following during the pandemic believes that the virus can not stay that much longer on surfaces.

The previous studies have also shown that it's not practically possible for the virus to stay alive on surfaces for this long. Some earlier laboratory trials have found that SARS-Cov-2 can survive for just 2-3 days on banknotes and glass, and up to six days on plastic and stainless steel.

However, the research from Australian agency CSIRO found the virus was "extremely robust," surviving for 28 days on smooth surfaces such as glass found on mobile phone screens and both plastic and paper banknotes when kept at 20 degree Celsius, which is about room temperature, and in the dark.

The Pakistani-American doctor who is currently serving as the Chief of Infectious Diseases at the University of Maryland Upper Chesapeake Health took to Twitter and asked the public to not panic in response to the research. He said that such studies are conducted in artificial lab conditions which are dark, damp, and without any body’s defenses, so they can't be taken too seriously.
