On March 17, the Central Epidemic Command Center (CECC) announced that due to the shortened incubation period of Omicron, individuals arriving in Taiwan on or after March 7 (incoming flight's scheduled arrival time) and close contacts of confirmed cases, who originally needed to take an at-home rapid test both on the third and either the sixth or seventh day of self-health management following the end of quarantine/isolation, will be required to take an at-home rapid test on both the second and the fourth day of their self-health management period starting today. Their test results should be reported back via text message to facilitate health authorities' timely health monitoring and implementation of necessary prevention measures.
