What is the size of foot and mouth virus?

The foot-and-mouth disease virus (FMDV) is relatively small, with a diameter of approximately 22 to 30 nanometers. It is a non-enveloped virus belonging to the Picornaviridae family, characterized by its icosahedral shape. The viral genome consists of single-stranded RNA, which is approximately 8,500 nucleotides long. This compact size allows the virus to be highly infectious and capable of rapid replication.
