On November 18, the Central Epidemic Command Center (CECC) announced two new confirmed imported cases of coronavirus disease 2019 (COVID-19) in Taiwan. Those two cases are an over 30-year-old female from Indonesia (Case #607) and a Taiwanese man in his 60s (Case #608). They arrived in Taiwan from Indonesia and the United States.

The Indonesian woman came to Taiwan to work on November 12. She developed a sore throat and aches all over her body on November 14, but she didn't notify the quarantine facility she stayed at. Because the Indonesian woman experienced a fever, runny nose, and sore throat on November 16, quarantine personnel arranged her medical care and COVID-19 testing. Infection with COVID-19 was laboratory-confirmed in the case on November 18.

The Taiwanese man resided in the United States for an extended period of time. He returned to Taiwan on November 11, and he didn't have physical discomfort upon arrival. The Taiwanese man began to develop slightly elevated temperature, muscle pain, and other symptoms on November 12. The health authority then arranged for him to seek medical care and be tested for COVID-19 on November 16. Infection with COVID-19 was laboratory-confirmed in the case on November 18.
