Health Desk- 12 Oct 2020: The virus responsible for Covid-19 can remain infectious on surfaces such as banknotes, phone screens and stainless steel for 28 days, researchers say.
The findings from Australia's national science agency suggest SARS-Cov-2 can survive for far longer than thought.
However, the experiment was conducted in the dark. UV light has already been shown to kill the virus.
Some experts have also thrown doubt on the actual threat posed by surface transmission in real life.
The coronavirus is mostly transmitted when people cough, sneeze or talk.
But there is also evidence that it can also be spread by particles hanging in the air. It is also possible someone could get Covid-19 by touching infected surfaces such as metal or plastic, according to the US Centers for Disease Control.
