The virus has proteins on its outer shell (capsid) that bind to the living host cell. Once the virus has attached to the cell, it enters the cell or inserts its DNA/RNA into the cell. When inside, the DNA/RNA instructs the cell to use the cell's resources to create more viruses. Viruses are not living, and do not have their own resources for creating new duplicates of themselves, which is why they must invade a living host's cells to replicate. After a while, when the host cell can no longer contain the amount of newly created viruses inside of it, the other protein that the virus carried on its capsid causes the cell to burst which releases the new viruses to go and attach to other cells in the host or perhaps to another host by contamination from the original host.

A virus enters host cells by attaching to specific cell receptors on the cell surface. Once attached, the virus can inject its genetic material into the cell, hijacking the cell's machinery to replicate itself. This process allows the virus to spread and infect other cells in the body.
The cells of mucous membranes are open to virus attacks because they are not covered by a skin.
No, a virus is not made up of cells. It is a small infectious agent that can only replicate inside the cells of living organisms.
red blood cells carry oxygen white blood cells attacks virus
When a virus attacks living cells and uses them to replicate and produce more viruses, it is known as viral replication.
The specific host cell for West Nile Virus is the neuronal cell in the central nervous system. Once inside these cells, the virus can replicate and cause damage, leading to neurological symptoms in infected individuals.
