CORONAVIRUS can remain infectious on surfaces like mobile phone screens and banknotes for up to a month, according to a study.
Researchers from Australia’s national scientific agency, CSIRO, have found that the SARS-COV-2 virus can survive for up to 28 days on glass and plastic surfaces.

The virus is most commonly transmitted through droplets when people cough, sneeze, or speak, but it can also be transmitted by particles that settle on surfaces like metal and plastic.
Previous studies have shown that the virus can survive between two and three days on banknotes and glass and up to six days on plastic and stainless steel, although the findings tend to vary.
Scientists have found that at room temperature, around 20 ° C, SARS-Cov-2 was “extremely robust”, surviving for 28 days in the glass found on mobile phone screens and plastic banknotes.
By comparison, the flu virus can survive under the same conditions for 17 days, according to the study.
Further tests were carried out at 30 ° C and 40 ° C respectively, and survival times decreased as the room temperature increased.
The experiments were carried out in the dark, as research suggests that direct sunlight can quickly kill the virus.
Dr Debbie Eagles, deputy director of the Australian Center for Disease Preparedness, said the findings “reinforce the importance of good practice” such as hand washing.
Dr. Sarah Jarvis, Patient.info’s GP and Clinical Director, told The Sun in March: “We know that most viruses survive much better on hard surfaces – phones and computer keyboards, as well as kitchen surfaces. .
“We also know that some viruses can survive for several days and definitely up to a couple of days.
“Even if no one else is using your phone, you will touch it regularly, and if you pick it up after washing your hands, you may still have traces of the virus that you put there before washing your hands.
“So it’s definitely worth cleaning your phone as much as washing your hands.”

It is recommended that alcohol-based wipes be used to clean mobiles as baby wipes are unlikely to kill germs effectively.
The average person picks up their phone 2,600 times a day and uses it about 76 times, according to research.
And typically, a phone carries more than 25,000 bacteria per square inch, making it dirtier than a kitchen counter, a dog bowl, or even a doorknob.
