On April 19, the Central Epidemic Command Center (CECC) announced that effective from 00:00 on April 20, 2022, testing rules for individuals identified as close contacts of confirmed cases and placed under home isolation and people who arrive in Taiwan on or after the specified time and are placed under home quarantine will be revised. Adjusted rules are listed below.

A. Individuals under home isolation: one rapid test or PCR test will be arranged once they are identified as contacts after contact tracing; a PCR test will be arranged for confirmation if they test positive in their rapid test. The four rapid tests previously required respectively on the fifth through seventh day of the isolation period, on the last day of the isolation period (the 10th day), and on the second and fourth days of the self-health management will be replaced by a rapid test on the last day of the isolation period. One additional rapid test kit will be provided and can be used if symptoms appear.

A. Individuals under home quarantine: the five rapid tests previously required respectively on the three through fifth day of the quarantine period, on the last day of the quarantine period (the 10th day), and on the second and fourth days of the self-health management will be replaced by a rapid test on the last day of the quarantine period. One additional rapid test kit will be provided and can be used if symptoms appear.

The CECC pointed out that in consideration of the age limit on who can use at-home rapid test kits, children under two years of age who are under home isolation/quarantine should undergo a PCR test. People who have difficulty using at-home rapid test kits on their own will receive rapid tests arranged and performed by local governments.
