Most virus growth occurs in epithelial cells. The virus or its nucleic acid then enters the host cell, where it takes control and utilizes the protoplasm of the host cell to produce new virus particles. This represents a concern for future epidemics and further underlines the need for a better understanding of the interplay between viruses and the MGT.
