When people talk about the coronavirus, they sometimes describe this invisible entity as if it has a personality and even a conscience. If you ask a biology or medical student what a virus is, they will tell you that a virus is not a living organism, or at most that it exists at the border between living and dead – a kind of walking dead.
For biologists who specialise in virology, however, this view is not clear-cut. Scientists still disagree on whether viruses are truly alive or not.
