Killing their host or disabling their host is generally disadvantagous to viruses, so viruses exist in the space where they duplicate enough within a host to spread to other people while still allowing the host to go out and infect other people.
If a virus mutation manage to still be infectious while having less effect on a person it’s more likely that don’t self-isolate and pass on the virus.
