When FMD virus comes in contact with a host cell, it binds to a receptor site and triggers a folding-in of the cell membrane.  Once the virus is inside the host cell, its protein coat dissolves.  New viral RNA and components of the protein coat are then synthesized in large quantities and assembled to form new viruses.  After assembly, the host cell lyses(bursts) and releases the new viruses.
