Foot-and-mouth disease is caused by FMDV, an [[Aphthovirus]] of the viral family [[Picornaviridae]].  The members of this family are small (25-30 nm), nonenveloped [[icosahedral]] viruses that contain single-stranded [[RNA]] (ribonucleic acid, the viral genetic material).  When such a 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 [[lysis|lyses]] (bursts) and releases the new [[viruses]]. There are seven FMD [[serotype]]s: O, A, C, SAT-1, SAT-2, SAT-3, and Asia-1. These serotypes show some regionality, and the O serotype is most common.

The members of this family are small (25-30 nm), nonenveloped icosahedral viruses that contain single-stranded RNA (ribonucleic acid, the viral genetic material).
