Roi Et Governor Chayan Sirimas said on Monday that the woman works at a karaoke joint in the Sriracha district of Chonburi province.
“She had close contact with another patient from Chonburi province [her younger sister] who tested positive earlier on January 9. She then took a test on January 10 at Roi Et Hospital and found that she was also infected.
