Foot and Mouth Disease (FMD) Pathology

The nature, cause, origin, and progress of Foot and Mouth Disease (FMD).

FMD is caused by a virus. The virus survives in lymph nodes and bone marrow, but is destroyed in muscle after rigor mortis. The virus can persist in contaminated fodder and the environment for up to one month, depending on the temperature and conditions.

There are at least seven separate types and many subtypes of the FMD virus. Immunity to one type does not protect an animal against other types.
