Why the study?
Continued circulation of African swine fever in wild boars and subsequent outbreaks in domestic pigs raised concerns about possible changes in virulence among circulating ASFV in South Korea.

Korean ASFV isolates retain acute virulence; leaves open whether field evolution will alter pathogenicity or control needs.
Korean ASFV isolates from 2019-2021 remain highly virulent, causing acute illness and rapid mortality in experimentally infected domestic pigs.
Cho et al. (2022) studied this question.
