The DDC on Wednesday allowed the second woman, a 34-year-old from Chaiyaphum province, return home. However, both took a second test this month when they went to Ramathibodi Hospital to get a Covid-19 health certificate to fly overseas. The second test showed she was free of the virus, so she was allowed to go home. It was on Aug 13 that she visited Ramathibodi Hospital to get her health certificate to fly overseas, which at this time returned a positive result. The woman drove to Bangkok on Sunday and visited the hospital at midday to get her Covid-19 health certificate allowing her to work overseas -- but this time her test was positive.
