[Persistence of FDMV and its effects on disease control strategies].

It is well-known that foot-and-mouth disease virus (FMDV) causes a persistent infection, lasting for more than 28 days, in cattle, sheep, goat as well as some other ruminant species, but not in pigs. Although convincing evidence for virus transmission is missing, these carrier animals have to be considered as a potential risk of infection. Some aspects of FMDV persistence are presented and discussed with regard to disease control strategies.
