At 20°C, coronavirus lives on phones and banknotes for up to 28 days

The decline in the incidence of whooping cough was recorded in Russia. In the first six months of 2020, there were one-third fewer such cases compared to last year. The results of the study are published in the Virology Journal.

Banknotes, glass, touch screens, metal pens and handrails can carry coronavirus infection for nearly a month, scientists from the Australian Center for Disease Preparedness have found. The SARS-CoV-2 virus is “extremely resistant” and can survive up to 28 days at room temperature on smooth surfaces such as smartphone glass and banknotes.

When the air was heated to 30 degrees Celsius, the virus remained on smooth surfaces for up to three weeks, and at 40 degrees it died in a few days. At the same time, porous surfaces (experts tested, in particular, cotton fabric) in this respect turned out to be less dangerous than smooth ones.

The survival of the influenza virus under similar conditions does not exceed 17 days, the study notes.

The scientists stressed that the screens of smartphones pose the greatest danger, because, unlike hands, people do not disinfect them as regularly.
