How Long Coronavirus Lasts On Various Surfaces

At a temperature of 68 degrees, SARS [and likely coronavirus] lasted:

— Less than 8 hours on latex
— 2 to 8 hours on aluminum
— 2 days on steel
— 4 days on wood
— 4 days on glass
— 5 days on metal
— 5 days on ceramics
— 5 days on plastics (but one strain survived up to 9 days on plastic)

In general, nonporous surfaces like doorknobs, desktops and airplane seat trays tend to transmit viruses better than porous surfaces such as paper money, human hair, rug pile and fabrics. The microscopic holes or spaces in porous surfaces can trap the microbes, preventing them from being transferred.

The easiest way to kill coronaviruses … is with a disinfectant. Solutions containing 62% to 71% ethanol alcohol, 0.5% hydrogen peroxide or 0.1% sodium hypochlorite will do the trick within a minute.
