The unsealed area of Xi is mainly concentrated in Yanta District, including the teaching area of West Campus of Chang 'an University, the teaching area of East Campus of Chang 'an University, the relatives' courtyard of East Campus of Chang 'an University, the residential area of Chongye Road of Chang 'an University, the relatives' courtyard of South Campus of Chang 'an University1,13, Yahe Cuihua Community of Cuihua North Road, and Jinxiu Community of West Extension, which was judged by the expert group of community prevention and control area. The conditions for unsealing Xi 'an area are as follows:

1. First, 14 days has not been added.

In recent 14 days, there were no new cases or asymptomatic infections in this area.

2. Second, the last close contact was quarantined 14 days.

The last 1 close contacts in this area were transported to a centralized isolation place for more than 14 days, and the nucleic acid test was negative. If there are new close contacts in the area after the close contacts who have moved to the centralized isolation place are diagnosed, the unsealing time shall be recalculated according to the transfer time of the new close contacts.

3. Third, all employees were negative for nucleic acid detection.

Two days before unsealing, all personnel in this area completed a round of nucleic acid screening, all of which were negative.

It should be noted that although some areas of Xi 'an have been unsealed, they are still under control and cannot leave the city. Therefore, whether migrant workers and students in Xi 'an can leave before the Spring Festival still needs to be completely unsealed.

When can Xi 'an be unsealed at the latest?

Xi 'an's latest unsealing time needs to wait until after the Spring Festival, that is, around mid-February. Because the Spring Festival holiday has ended at this time, if it is all unsealed at this time, it will also be beneficial to the prevention and control of epidemic situation in various provinces and cities.
