Hello

I know that virus is not a living organism, but is it still normal to
refer to a functionable virus as "living"?

The reason for this question is some quotas I've read in newspapers.
It's about the danger of finding intact and active virus in a 80 year
old grave containing corpses who died of a disease caused by this virus.

Commenting on this risk, many scientists referred to such viruses as
"living". It struck me as strange to call a biological robot as being
alive, just as strange as calling my car living when it's not broken, or

my computer living when it's not crashed.

Sincerely,
Trond Erik Vee Aune

Dear Trond Erik,
Well, it's a matter of definition - you can say that a virus, like a spore
or seed, has the potential of reproduction given the right conditions.
However, if a virus is defined as "alive" you may have to include other
genetic elements like plasmids and transposons which also have the potential
to reproduce.

Maybe there is a continuous spectrum between living and non-living.

It was easier when a living thing was moving or growing...

yours

Lars
