How long can COVID-19 live on surfaces?

ANSWER

Most viruses can live for several hours on a surface that they land on. A variety of studies are looking at how long the virus stays alive on a variety of surfaces.  One study showed the virus lived for up to 4 hours on copper, up to 24 hours on cardboard, and up to 2 to 3 days on plastic or stainless steel.

It is still unclear if this increases the chance of transmission.  From what we know so far – transmission from surfaces is much lower risk than person to person.  It’s always a good idea to disinfect surfaces to get rid of the virus.
