Genetic analysis links South Korean African swine fever virus to European and Chinese genotype II strains.
The 2019 African swine fever virus outbreaks in South Korean domestic pigs were caused by genotype II, serogroup 8 isolates genetically identical to certain European and Chinese strains.

May inform ASFV surveillance across Asia; leaves open functional and transmission studies in swine.
On 17 September 2019, the first outbreak of African swine fever in a pig farm was confirmed in South Korea. By 9 October, 14 outbreaks of ASF in domestic pigs had been diagnosed in 4 cities/counties. We isolated viruses from all infected farms and performed genetic characterization. The phylogenetic analysis showed that all of fourteen ASFV isolates in South Korea belong to genotype II and serogroup 8. Additionally, all isolates had an intergenic region (IGR) II variant with additional tandem repeat sequences (TRSs) between the I73R and I329L genes and showed characteristics of central variable region (CVR) 1 of the B602L gene and IGR 1 of MGF 505 9R/10R genes. These are identical to the genetic characteristics of some European isolates and Chinese isolates.

Kim et al. (2020) studied African swine fever (n=14). Viral isolation and genetic characterization was evaluated on Viral genotype and genetic characteristics. Genetic characterization of 14 African swine fever virus isolates from South Korea showed all belong to genotype II and serogroup 8, identical to some European and Chinese isolates.
