They are obligate in the sense that they cannot replicate outside of a host cell.
To make a copy of itself, a virus must first enter a cell (intracellular), hijack the machinations of said cell (parasitic behavior) and then copy itself.

∙ 12y agoVirus becomes parasite and plays its role after it gets inside a living thing ,there life is like made to get inside the livingthing and play it's role therfore their getting of parasite only after getting inside a living thing is said as an obligation for them to be a parasite when they are not inside livingthing i.e,there main life phase in which they are out of the livingthing where nature gives virus a beggining form which is out of living thing hence, it sustains in obligation to be a parasite so,virus are obligatory parasite.

Organisms who use another organism to flourish are called parasites.
Do parasites cause rabies?
Yes. Rabies is a virus and could be called a parasite.
Do parasites have mitochondria?
Virus and bacteria do not have.Other eukaryotic paracites have
Is flu an example of a parasite or protozoan?
Neither; influenza ("the flu") is caused by a virus; in particular, an RNA virus of the family Orthomyxoviridae, of which there are several varieties. The flu virus could be thought of as parasitic, since it does invade host cells and use these cells for its replication. But though some biologists may consider bacteria and viruses to be parasites, the medical field does not.
How are viruses similar to parasites?
Viruses are similar to parasites because both require a host to survive and both destroy the cells in which they multiply (cause harm to the host).
Is the reason viruses are called obligatory intracellular parasites because they require a cell host to replicate?
yes.
