SEOUL--A South Korean man accused of lying to authorities about his job and whereabouts during a coronavirus tracing probe was sentenced to six months in prison, Yonhap news agency reported on Thursday.

Prosecutors, who has asked for a two-year sentence, said infections in at least 80 other people were traced to the man.

According to Yonhap, the man apologized in court, saying he did not realize the serious repercussions of his actions.
