Summary. Epidemic situation on foot-and-mouth disease (FMD) in Iran in 2005-2014 is analyzed in the article. Epidemiological characterization of the analyzed outbreaks was taken from the OIE and World Reference Laboratory databases. Analysis of the epidemic situation and historical examination of FMD free status in Iran were carried out in accordance with Chapter 1.4. Animal Health Surveillance and Chapter 1.6. Procedures for self declaration and for official recognition by the OIE of the OIE Terrestrial Animal Health Code 2014. Analysis of the notification data submitted by Iran to the OIE showed that FMD was reported in all Iranian provinces in 2006, 2009, 2010, 2012 and 2013. Only 1 – 6 provinces were free from FMD in 2005, 2007, 2008 and 2011. In 2010 – 2014 FMD was reported in 1.6 – 12.0% of cattle, 1.7 – 5.8% of goats and 1.5 – 8.9 % of sheep located in the outbreak areas. Deaths of FMD-affected young cattle (1.7 – 14.7 %), young goats (17.8 – 43%) and young sheep (5.4 – 22.0%) were registered. This indicates that FMD is endemic in Iran. FMD outbreaks caused by the following FMDV types were registered in the territory of Iran: type O MESA topotype, Pan Asia-2 genetic line (sublines: ANT-10, FAR-09, Ind-2001); type A, Asia topotype, Iran 05 genetic line (sublines: HER-10, SIS-10, SIS-12, AFG-07, FAR-09, FAR-11, BAR-08); type Asia-1, Asia topotype, Sind genetic line, subline 08. In Iranian provinces bordering Armenia (West Azerbaijan and East Azerbaijan) 887 and 1133 FMD outbreaks were reported in 2005 – 2009 and in 2010 – 2014, respectively. In Iranian provinces bordering Azerbaijan (East Azerbaijan, Ardabile, Gilan) 826 and 963 FMD outbreaks were reported in 2005 – 2009 and in 2010 – 2014, respectively. In Iranian provinces bordering Turkmenistan (Golestan, North Khorasan, Khorasan, Razavi) 391 and 987 FMD outbreaks were reported in 2005 – 2009 and in 2010 – 2014, respectively.

Key words: Iran, foot-and-mouth disease, type O, type A, type Asia-1, cattle, sheep, goats, buffaloes, deer, anti-FMD vaccination.
