Abstract:
Foot-and-mouth disease virus is a positive stand RNA virus that causes an acute vesicular disease of bovid wild and
domesticated ruminants. Foot-and-mouth disease virus (FMDV) comprises of 7 antigenically distinct serotypes (Type O,
A, Asia 1, C and SAT1-3) that do not provide cross-protection against one another. Foot-and-mouth disease (FMD) is a
pandemic disease, accounting for a global loss of 6.5-21 billion US$ per annum. The present investigation aimed at the
comparison of FMDV in Bangladesh with that of circulatory types in Asian continent. Categorization, estimation and
demography of FMD in Asia continent are analyzed. Comparative genome and phylogeography of the FMDV in Asia is
discussed. Three serotypes of FMDV are circulating in Asian territory, including mainland Southeast Asia, South Asia
and Middle East with predominance of type O, whereas Serotype A and Asia1 are found to be confined to certain
geographical regions. Cattle are most susceptible to FMD, whereas Pig serves as mixing vessel that may boost the
emergence and re-emergence episode of several lineages/genotypes. Whole Genome and phylogeography analysis
revealed that the transboundary movement of FMDVs are responsible for spreading of this disease in Asian regions. In
2013-2015, Saudi Arabia experienced the emergence of Ind-2001 lineage under Middle East South Asia (ME-SA)
topotype of FMDV type O and Genotype VII of FMDV type A, which is normally endemic in the Indian subcontinent.
Intrusion of type SAT1-3 in Arabian Peninsula occurred due to transboundary animal movement from FMDV enzootic
African countries. Transboundary movement of FMDV, inappropriate vaccination and inadequate awareness are the
main reasons for FMD spread in most of the Asian Countries.
