Stay safe advice

. . . NIH researchers compared the new coronavirus' lifespan on surfaces to that of the SARS coronavirus. They found that both coronaviruses lived the longest on stainless steel and polypropylene, a type of plastic used in everything from toys to car parts. Both viruses lasted up to 3 days on plastic, and the new coronavirus lasted up to 3 days on steel.

On cardboard, however, the new coronavirus lasted three times longer than SARS did: 24 hours, compared to 8 hours.
Another study published last week in the Journal of Hospital Infection looked at the lifespans of other coronaviruses found in humans on various surfaces. The SARS coronavirus, at a temperature of 68 degrees Fahrenheit (20 degrees Celsius), lasted for two days on steel, four days on wood and glass, and five days on metal, plastic, and ceramics. (The researchers also found that one strain of SARS lasted up to nine days on a plastic surface at room temperature.)
SARS survived for two to eight hours on aluminum and for less than eight hours on latex.
According to Graham, smooth, nonporous surfaces like doorknobs and tabletops are better at carrying viruses in general. Porous surfaces — like money, hair, and fabric — don't allow viruses to survive as long because the small spaces or holes in them can trap the microbe and prevent its transfer, Graham said.
