The Taiwanese man, who went to Mexico for work purposes in November 2020, developed a sore throat and a cough on Jan. 3 and tested positive on Jan. 6 while he was there, the CECC said.
In the period Jan. 7-23, he was hospitalized and subsequently quarantined at a hotel in Mexico, the CECC said in a news release.
The man returned to Taiwan on a medical charter flight Sunday and was transferred immediately to a negative pressure hospital room and tested again for COVID-19, according to the CECC.
While the test came back positive Tuesday, there was no need for contact tracing, as all medical workers and individuals known to have had contact with him were wearing personal protective equipment, the center said.
