About Covid19

Key points:-

HCoV-19…

– remained viable in aerosols throughout the duration of [the] experiment
(3 hours).

– was most stable on plastic and stainless steel and viable virus could
be detected up to 72 hours post application.

– No viable virus could be measured after 4 hours on copper or after
24 hours on cardboard.

So it *does* appear to hang around in the air, and can last up to 3
days on plastic surfaces. I was surprised with the cardboard result.

None of this is to say that these are the main methods of current
transmission, but they are interesting nevertheless
