Coronavirus can continue to exist on face masks for a week, banknotes for days: Stare

A watch by American researchers on the environmental stability of the coronavirus printed final month in the journal Nature also concluded that it will remain infectious on some surfaces for days.

The unconventional coronavirus that causes Covid-19 can remain infectious on face masks for up to a week, and final on banknotes, chrome steel and plastic surfaces for days, in response to a watch.

Nevertheless, the virus will also be killed by family disinfectants, bleach or frequent hand washing with soap and water, said the researchers from the University of Hong Kong (HKU).

The watch chanced on that the COVID-19 virus can follow chrome steel and plastic surfaces for up to four days, and to the outer layer of a face conceal for a week, Hong Kong-essentially based entirely South China Morning Publish (SCMP) reported on Monday.

A watch by American researchers on the environmental stability of the coronavirus printed final month in the journal Nature also concluded that it will remain infectious on some surfaces for days.

They chanced on the virus became indicate on plastic and steel for up to 72 hours, but didn’t final more than four hours on copper or 24 hours on cardboard.
