On April 25, the Central Epidemic Command Center (CECC) announced the following measures:
I. "Key contact tracing" will be implemented beginning today:
A. A close contact is an individual who had contact with a confirmed case in the two days before the confirmed case had onset of disease or tested positive (asymptomatic case).
B. Close contacts include friends or relatives living in the same residence as confirmed cases, their classmates, or their colleagues in the same office or workplace (identified through a 3 by 3 grid).
C. Self-initiated responsive measures should be taken. Confirmed cases should voluntarily provide a list of people living with them as well as the epidemic prevention coordinators at their schools or companies.
D. The "self-reporting contact tracing system" for confirmed cases should be established.
II. The home isolation period will be shortened to a 3+4 plan (three days of isolation followed by four days of self-initiated epidemic prevention) beginning from April 26. This rule will retroactively apply to individuals who have been placed under isolation for more than three days, and they will be released from isolation starting April 27.
A. During the three-day home isolation, individuals must stay at home and abide by the one person per room principle; they must not go out.
B. After an individual is identified as a contact, one rapid test will be arranged for the individual, who will undergo a PCR test if he or she tests positive on the rapid test. During the isolation period, the individual should take a rapid test if symptoms occur and on the third day (the last day); the individual should remain in isolation if he or she tests positive. If the individual tests negative, the individual should practice a four-day self-initiated epidemic prevention period and be released from self-initiated epidemic prevention after testing negative on the seventh day.
C. Precautions to take in the self-initiated epidemic prevention period:
1. A rapid test should be taken every day during this period. Individuals who test negative can go out to work or to buy daily necessities.
2. Masks must be worn at all times when outside.
3. Dining at restaurants, eating out with other people, attending gatherings, and visiting crowded places or places where they come into contact with non-specific persons are prohibited.
4. Individuals testing positive on rapid tests are banned from taking public transportation, but they can visit community testing sites for PCR testing by driving or riding themselves or riding with their friends or relatives (both parties must wear masks at all times). If the testing site is nearby, they can also go there on foot directly without having to await instructions of health authorities. They can also follow the instructions of their local health authorities on seeking medical attention for people testing positive by rapid test.
