Coronavirus particles can ‘survive on phone screens for up to four weeks’

Coronavirus particles can survive for up to four weeks on phone screens, according to experts.

With research continuously shedding light on the fairly new virus, a study has claimed the particles can also survive on bank notes.

The bug was found to be "extremely robust" at 20C, or room temperature – however it survives for less time at hotter temperatures – according to Australia's national science agency CSIRO.

Scientists conducted the research by drying virus in an artificial mucus on different surfaces, at concentrations similar to those reported in samples from infected patients and then re-isolating the virus over a month.

The study was also carried out in the dark, as research has demonstrated direct sunlight can rapidly inactivate the virus.

Dr Debbie Eagles, deputy director of the Australian Centre for Disease Preparedness, 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 handwashing 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, published in Virology Journal, suggest the virus survives longer on smooth surfaces such as glass, stainless steel and vinyl, compared to porous surfaces such as cotton.

Recently it was also revealed coronavirus can survive on frozen meat, chicken and fish for 21 days.

In a study slices of salmon, chicken and pork from Singapore supermarkets were laced with the virus.

They were then stored between 4C, which is standard refrigeration temperature, and minus 20C.

And after 21 days, the coronavirus was still latching onto the meat and fish samples, the Sunday Telegraph reported.
