Can a virus get a virus?

Can there be or possible be out there a virus, or some other sort of pathogin, that attacks other viruses? Buy hijacking their structure.

Virusus have DNA like cells do, if viruses hijack DNA, then the key ingredient is shared, so its possible.

can a virus get 'sick'?

no

Yeah why not I think they're called virofages

Google "antigenic shift viruses"

It's why we need a yearly flu shot instead of just one every decade to account for random mutations

Are you retarded? First: a virus is a RNA + protein shell. Ist reproduces by injecting its RNA into a specific cell or sometimes bacteria for which its protein shell is build.
Second: It doesn't do or is anything else.
Thats like asking if a battery can get sick.

I don't think so. Viruses rely on cellular mechanisms to reproduce and viruses are not nearly as sophisticated as cells.

You might be able to change the viral rna or protein shell. But thats about it.

Viruses are not alive and cannot self replicate without a host.

They are more or less a strand of DNA or RNA. If they got infected, I think they basically would be considered a different or evolved virus.

In fact, humans splice our man-made/designer DNA/RNA into viruses so that we can use them as vectors, so in a way we "infect" them...

What about the idea of all cells and viruses sharing a common ancestor?
