Upon arrival, she voluntarily notified airport quarantine officers that she experienced an itchy throat. Her specimen was then collected for COVID-19 testing at the airport.

The health authority arranged for him to seek medical attention and undergo a COVID-19 test on January 1, 2021. Infection with COVID-19 was laboratory-confirmed in the case on January 3.
