How long does COVID-19 survive on surfaces?

It is not certain how long the virus that causes COVID-19 survives on surfaces, but it seems to behave like other coronaviruses. Studies suggest that coronaviruses (including preliminary information on the COVID-19 virus) may persist on surfaces for a few hours or up to several days. This may vary under different conditions (e.g. type of surface, temperature or humidity of the environment).

A new analysis found that the virus can remain viable in the air for up to three hours, on copper for up to four hours, on cardboard up to 24 hours and on plastic and stainless steel up to 72 hours. This study was originally published in the preprint database medRxiv on March 11,  and now a revised version was published March 17 in The New England Journal of Medicine.

The surveys concluded that if this new coronavirus resembles other human coronaviruses, such as its “cousins” that cause SARS and MERS, it can stay on surfaces —  such as metal, glass or plastic — for as long as nine days (In comparison, flu viruses can last on surfaces for only about 48 hours.)

However, some do not remain active for as long at temperatures higher than 30 degrees Celsius. The authors also found that these coronaviruses can be effectively wiped away by household disinfectants.

For example, disinfectants with 62-71% ethanol, 0.5% hydrogen peroxide or 0.1% sodium hypochlorite (bleach) can “efficiently” inactivate coronaviruses within a minute, according to the study.

“We expect a similar effect against the 2019-nCoV,” the researchers wrote, referring to the new coronavirus. But even though the new coronavirus is a similar strain to the SARS coronavirus, it’s not clear if it will behave in the same way.
