On April 27, the Central Epidemic Command Center (CECC) announced it will change quarantine regulations and disease prevention measures for crew members of Taiwanese airlines returning to Taiwan starting from May 1 (incoming flight's scheduled arrival time). Related adjustments are listed below.

1. Crew members returning from countries under Level 3 travel notice (long-haul flights):

a. Those who have received a COVID-19 booster shot for at least 14 days: a three-day home quarantine (one person per room and going out is not allowed) and a four-day self-health management (a PCR test on Day 0 and a rapid test or PCR test every day from Day 4 to Day 7).
b. Those who have not received a booster shot (including those who have received a booster dose for a period of less than 14 days): a five-day home quarantine (a PCR test on Day 5) and a nine-day enhanced self-health management (PCR tests on Day 9 and Day 14).

2. Crew members who have not entered countries under Level 3 travel notice and have returned to Taiwan the same day (short-haul flights):

a. Those who have received a COVID-19 booster shot for at least 14 days: a five-day self-health monitoring and a mandatory rapid test or PCR test every five days.
b. Those who have not received a booster shot (including those who have received a booster for a period of less than 14 days): rules remain unchanged; a seven-day self-health management and PCR testing every seven days.
