Taiwan reported a new imported case of COVID-19 on Friday involving an Indonesian national who arrived in the country last month to go to work on a fishing boat, according to the Central Epidemic Command centre (CECC).
The Indonesian, in his 20s, arrived in Taiwan on December 31 with a negative test report upon arrival, CECC spokesman Chuang Jen-hsiang said at a press event in Taipei, and did not show any symptoms of the disease.
He was tested again for COVID-19 prior to his release from his 14-day mandatory quarantine on January 13, and the result came back positive on Friday.
Due to the high CT value of the test, which indicates the presence of only a small amount of viral genetic material and that the infection may have run its course, Chuang said the worker was most likely infected quite a while ago in Indonesia.
No contact tracing was needed as the worker had not come in contact with anyone during the time he has been in Taiwan, Chuang said.
Meanwhile, the CECC official said it is expanding its testing to another 452 workers at a hospital in northern Taiwan where two domestically transmitted COVID-19 cases involving a doctor and a nurse were reported earlier this week.
A total of 468 people in the hospital had already been tested, and the new group consists of those who had even brief contact with the infected doctor and nurse, with results expected to come back Saturday at the earliest, Chuang said.
To date, Taiwan has recorded 843 cases of COVID-19, with 746 classified as imported. Of the total, 741 have recovered, seven have died and 95 remain in the hospital, CECC data showed.
