The outbreak of Foot-and-Mouth disease (FMD) on 2010/2011 was the largest scale occurred in Republic of Korea. From 28∨th of November 2010 to 21∨st of April 2011, during 144 days 3,784 farms were confirmed positive to FMD. During the epidemic, 5 types of farms raising cloven-hoofed animals were affected: beef cattle, dairy cattle, swine, goats and deer. The most seriously affected farm type was swine farms. The first infection was reported from the complex of swine farms in Andong-si, Gyeongsang buk-do. In Gyeongsang buk-do, beef cattle farms are densely located and Gyeonggi-do has lots of dairy cattle farms and swine farms. These distinct characteristics of areas took important role to make different patterns of outbreaks. Therefore, even the index case was started from complex of swine farms, many beef cattle farms were also infected in Gyeongsang buk-do. The most damaged species in this epidemic was swine, as approximately 20% of total swine farms were affected at the end of the epidemic in the Republic of Korea. Previous works on epidemiological analysis describing the infectious disease have focused on the results such as the percent of damaged farms and animals. However, in this study, we describe the temporal patterns of FMD outbreaks in the course of the 145 days of the epidemic period according to the different farms types. Furthermore we analyze the correlation between major issues of the epidemic and the outbreak pattern, considering the distinct characteristic of the area.
