Prime Minister Han Duck-soo presides over a meeting on African swine fever (ASF) at the government complex in Seoul, Friday, as an ASF case was confirmed at a pig farm in Yanggu.

Prime Minister Han Duck-soo on Friday called for vigilance in efforts to contain the outbreak of African swine fever, a day after officials reported this year's second case of the virus, which is deadly to pigs but not harmful to humans.

The second case was confirmed at a pig farm in Yanggu, a county located about 175 kilometers northeast of Seoul, late Thursday, according to the agriculture ministry.

"Along with swift anti-epidemic measures, thorough anti-epidemic management is needed to prevent further spread," Han told a virus response meeting.
