We finally have
a study directly on this specific virus and how long it can survive on surfaces.
The results: detectable in aerosols for up to 3 hrs, up to 24 hrs on cardboard and up to 2-3 days on plastic/stainless steel.
This really highlights the importance of washing your hands and cleaning surfaces that are commonly used in households.
Another study found that cleaning surfaces with proper disinfectants effectively decontaminated the virus.
