In a study funded by the US National Institutes of Health it was found that coronaviruses can stay viable for up to 72 hours after being placed on stainless steel and plastic, up to 24 hours after being put on cardboard, 4 hours for copper and in aerosol form (when someone coughs, sneezes etc), it remained viable “throughout the duration of the experiment” of three hours, a separate study published last month in The Journal of Hospital Infection found that human coronaviruses, have been found to persist on inanimate surfaces — including metal, glass or plastic surfaces — for as long as nine days if that surface had not been disinfected, there was also a report on Sky news that when one of the infected cruise ships was released from quarantine traces of the virus were found 17 days after the date the ship had been evacuated.

The Senior lecturer on the subject from Reading University said on Sky news that the virus changed as it passes through infected people currently he said there were 8 strains identified.

The virus is destroyed on contact with alcohol (over 70% proof) other useful substances are chlorine (bleach), hydrogen peroxide, iodine-based antiseptics and because coronavirus molecules are encased in a layer of fat, detergents (soap) are effective because they dissolve the fat and destroy the viability.
