If you don't stay for three days, how can you have two inspections in three days?

Then you can't check it twice every three days.

1, two tests in three days means two nucleic acid tests in three days (72 hours) with an interval of 24 hours. Usually, a nucleic acid test is performed on the first day and a second nucleic acid test is performed on the third day.

The interval between 2.3 days and 2 days inspection is calculated from the first sampling. It is suggested to go to the nearest inspection institution or hospital for nucleic acid detection as soon as possible after receiving the short message of "3-day 2-test", and enter through the special channel for yellow code personnel according to regulations. Wear a mask when checking, and keep a certain social distance from others to prevent face-to-face communication with others.

Omicron mutant infection has a latent period, which means that there is a process of virus replication, and the virus can only be detected after it has been replicated to a certain extent. The human body itself is immune, so once infected, the virus and the body will also play a game. As an objective index, nucleic acid detection can find the infected people in a large number of people as soon as possible and block the source of infection.
