On December 28, the Central Epidemic Command Center (CECC) announced that, in response to the rising cases in China and to detect high-risk variants in a timely manner, passengers arriving in Taiwan from four Chinese airports on direct cross-strait flights and those coming to Taiwan through the special travel arrangement for the residents of Kinmen and Matsu counties during the Lunar New Year holiday will be required to undergo a saliva-based PCR test at the airport (or port) of entry, starting from January 1 to January 31, 2023 (incoming flight's scheduled arrival time). The current policy of suspending the entry of Chinese tourists remains. After undergoing a PCR test at the airport, such travelers should go to their place of accommodation to undergo a seven-day period of self-initiated prevention and take COVID-19 tests during that period. Passengers who test positive should follow the 5+n home care policy and practice self-health management. Samples from people positive for COVID-19 will be sent to the Kunyang Laboratory of Taiwan CDC for virus genome sequencing.
