ABSTRACT
Foot-and-mouth disease (FMD) is a highly infectious and contagious transboundary animal disease and one of the most economically devastating diseases that affect cloven-hoofed livestock including cattle, goats, sheep, pigs and wild ungulates. Wide prevalence of the disease in Asia and Africa associated with huge economic losses to livestock farming and industry has increased global concern for the disease. Currently, 3 serotypes of FMD virus (O, A and SAT-2) and 06 lineage are circulating in the North Africa, of which serotype O is responsible for most of the outbreaks. However, the rapid spread of SAT2 and other exotic FMDV lineages in Libya and Egypt demonstrated the need for a robust surveillance system to detect and respond effectively to exotic infections. Emergence and re-emergence of FMD virus genotypes/lineages has been detected necessitating frequent replacement of the vaccine strains. The present review summarizes the knowledge generated in epidemiology, diagnosis and surveillance of the disease in the Maghreb countries.
