Coronavirus lived on Diamond Princess cruise ship for up to 17 days, CDC says

Earlier this month, researchers found that the novel coronavirus COVID-19 can remain in the air for up to three hours, and live on surfaces such as plastic and stainless steel for up to three days.

The study, which has not been peer-reviewed yet, also notes that the virus can remain on copper surfaces for four hours and cardboard for up to 24 hours.

A separate study published in February concluded that if COVID-19 is similar to other coronaviruses, such as SARS or MERS, it could live on surfaces like metal, glass and plastic for up to nine days, Fox News previously reported.

By comparison, the flu virus can only live on surfaces for approximately 48 hours.

This means use those disinfecting wipes you (hopefully) bought and wipe down all the cans and outside of all the packages you bring into the house.  And handle the mail with gloves.
