On May 29, the Central Epidemic Command Center (CECC) announced one new confirmed imported case of coronavirus disease 2019 (COVID-19) in Taiwan. Case #442 is an over 20-year-old male who visited Russia for study in February. The case took a flight back to Taiwan with 95 other Taiwanese nationals, transiting through Japan, and arrived in Taiwan on the early morning of May 26.

The CECC reported that the case had a sore throat on May 15 and developed a loss of sense of smell and fatigue on May 16. He voluntarily reported his symptoms to quarantine officers at the airport upon arrival in Taiwan. After the quarantine officers collected his specimen for testing, he was transported to a group quarantine facility. The case later tested negative for COVID-19. However, the case had developed abnormal sense of smell; thus, he was given a second test on May 28. Infection with COVID-19 was laboratory-confirmed in the case on May 29. The case is currently hospitalized for medical treatment in isolation. The 95 individuals who returned to Taiwan with the case all tested negative for COVID-19, and the CECC continues to monitor their health status in the group quarantine facility.
