similar viruses don't really compete. you can be infected with multiple COVIDs at the same time. the older variants disappear because of mass immunity, not because of competition.

They are competing for resources in terms of susceptible individuals. If virus A is more transmissible, replicates in cells more quickly, or bypasses immunity that would otherwise prevent infection with virus B, then virus A has outcompeted virus B.

With evolution, everything is competition.
