Key result
The July-August 2014 foot-and-mouth disease outbreak in South Korea was caused by a novel type O virus (Mya-98 strain) featuring a 23-amino acid deletion in the 3A/3B1 region and low pathogenicity.
Observational
This report details a novel foot-and-mouth disease outbreak in vaccinated Korean pig farms, highlighting the need for ongoing surveillance and genetic analysis.
Supports expanded FMDV sequencing in outbreaks; leaves open vaccine strain selection updates.
Foot-and-mouth disease (FMD) O, A, and Asia 1 type viruses have been circulating in Asian countries In Korea, FMD occurred once in 2000, once in 2002, and three times in 2010, making a total of five outbreaks since 2000 All animals susceptible to FMD were vaccinated in early 2011 to help prevent recurrence of the disease. Since that time, due to concerns about a recurrence, vaccines against three serotypes, O, A, and Asia 1, have continued to be vaccinated (O1 Manisa, A Malaysia 97, and Asia 1 Shamir) In July-August 2014, FMD occurred on three pig farms in Uiseong and Goryeong in Gyeongbuk province and in Hapcheon in Gyeongnam province. This paper describes the outbreak, the diagnosis, the quarantine measures for FMD under the condition of vaccination and pathogenesis, genetic analysis of the isolated virus.
