why do viruses try to kill the thing keeping them alive?
In: Biology
Viruses don’t “try” to do anything but reproduce. Viruses that kill their hosts too quickly are very poor at spreading and reproducing. The most immediately dangerous viruses like E bola hardly spread at all because their hosts collapse into a puddle of their own blood and scare off all the other humans. Viruses that spread well typically leave the host well enough to get around and infect other people. COVID could be spread 2 or 3 days before you started showing symptoms. The part about being sick or nearly dead or barely sick is not part of a virus’s strategy/design; it’s part of the host body’s immune system design.
