Taipei-Taiwan on Friday confirmed one new imported case of COVID-19, a United States citizen in his 50s, according to the Central Epidemic Command Center (CECC).
The man, who had proof of a negative COVID-19 test result issued within three days of his flight as required, showed no symptoms when he entered Taiwan on a business trip on Jan. 26, the CECC said.
It was not until after he had a test at his own expense upon the completion of his home quarantine on Feb. 10 that he was found to have contracted the disease, the center said.
According to the CECC, the man's test on Feb. 10 showed a Ct level of 33 and a test taken the next day showed he had a Ct level of 31. Ct-values (usually in the 30s or high 30s) generally indicate lower viral loads.
Further tests showed that he had IgG antibodies but no IgM antibodies, which indicate he was infected with COVID-19 over a month ago, the CECC said.
Seven of the contacts with which the man had are under self-health management, it added.
To date, Taiwan has recorded 937 cases of COVID-19, 821 of which have been classified as imported. Of the total, 859 patients have recovered, nine have died and 69 are in hospital, according to CECC statistics as of Friday.
