Carriers of foot-and-mouth disease virus: a review
2000
Abstract This review describes current knowledge about persistent foot‐and‐mouth disease virus (FMDV) infections, the available methods to detect carrier animals, the properties of persisting virus, the immunological mechanisms, and the risk of transmission. In particular, knowledge about the carrier state, the period in which virus can be isolated from animals 28 days or longer post infection, is important, because the risk that animals may carry the virus will influence the diagnostic and preventive measures that need to be taken. Although many years of research have led to much knowledge about foot‐and‐mouth disease and its causative agent, there are still numerous aspects of the virus and the disease that are not yet fully understood. Areas for further research on persistence of FMDV are discussed.
