Viruses Are Sneaky Little Creatures

Viruses are not “alive” in any sense of the word; they are just biological machines. Their prime directive: make more viruses.

That’s it. To achieve their prime directive, they invade cells in your body, take over their machinery and pump out more viruses. Different viruses infect different kinds of cells — — lung, brain, liver, heart, blood vessels — but they don’t know — and don’t care — if their invasion kills off the body it’s taken over; they only know how to do this one thing.
