The researchers compared the new coronavirus life span on surfaces with that of the SARS coronavirus in a 70-degree Fahrenheit room at 40% relative humidity. They found that both coronaviruses lived the longest on stainless steel and polypropylene, a type of plastic used in everything from Tupperware to toys. Both viruses lasted up to three days on plastic, and the new coronavirus lasted up to three days on steel.
