As of 8 o'clock on October 23, 783,141 nucleic acid samples were expanded in key areas of Zunyi City, and 501,692 were tested with negative results. The remaining samples are being tested.
Among them, the central four urban areas are: Huichuan District sampled 314,693 person-times and detected 186055 person-times; Honghuagang District sampled 230,674 person-times and detected 159,606 person-times; Bozhou District sampled 36,387 person-times and 16612 person-times tested; Xinpu New District sampled 27,854 person-times and detected 13,404 person-times Person times.

Sichuan District, Banzhou District, Xinpu New District) organize nucleic acid testing for all employees.
Li Xie said that there are two main considerations for launching the nucleic acid test for all employees in the downtown area of Zunyi. Check.
Second, in the nucleic acid detection process, there is a risk that a very small number of people will not be detected, which is likely to cause a small probability of missed detection.
