Viral Replication

Virologists describe the formation of viruses during the infection process in target host cells as viral replication.

Viral infection involves the incorporation of viral DNA into a host cell, replication of that material, and the release of the new viruses.

Host tropism refers to the way in which viruses/pathogens determine which cells become infected by a given pathogen.

Animal viruses have their genetic material copied by a host cell after which they are released into the environment to cause disease.

Plant viruses are often spread from plant to plant by organisms known as vectors.
