why do viruses try to kill the thing keeping them alive?
In: Biology
They don’t. All viruses want to use their host to make more of themselves. Most hosts want to get rid of the virus. The immune response is often wheat makes viruses dangerous to us if the virus is string enough.
When viruses themselves are deadly, it’s usually because the virus made a jump to a different species, and it doesn’t realize what it’s doing it deadly. This is why, over time, an individual virus becomes less deadly to a species. The common cold is the same kind of virus as covid-19, but it has been circulating among humans for so long, that it’s no longer dangerous to us. Covid-19 made the jump to humans in 2019 and now it’s 2024, and in addition to us getting better at fighting it, there are also plenty of variants now that are less deadly to us, and that’s just 5 years.
