The source of the epidemic infection in Xi 'an is not particularly clear, but the deputy director of the local CDC also responded and analyzed the relevant issues. The main contents are as follows:

11. Experts said that according to the survey results, most of the epidemic victims in Xi 'an were related to the Shaanxi Zhaohui renewable resources trading and distribution market. That is to say, although the specific source of epidemic infection is not particularly clear now, there is definitely a big problem in this trading market, so now this trading market is completely closed. In addition, according to the test results, the viruses infected by this positive infection are all branches of the mutant strain BA.5.2

12. This epidemic also has many characteristics. For example, this epidemic in Xi 'an was discovered earlier and handled in a timely manner. Relevant departments also tested key personnel, and most of them were in the state of early infection. Secondly, most of the infected people in this epidemic are related to waste recyclers. Finally, this epidemic has obvious clustering, and many infected people have had contact history of working together or living together.

13. Although the final source of infection has not been found, what is certain now is that the virus came from abroad. And this is also a wake-up call for everyone and relevant departments. Experts also remind relevant departments that it is necessary to do a good job in preventing foreign virus input.

14. After the outbreak, local experts in Xi 'an also reminded the general public that they must actively cooperate. After the outbreak, the relevant departments in Xi 'an will temporarily control some areas, which may bring some inconvenience to the citizens, but the citizens still need understanding and support, and the citizens themselves need to actively participate in various epidemic prevention measures. In addition, citizens should take the initiative to report if they have crossed the trajectory of inflammatory cases before, and at the same time, they should do a good job in personal epidemic protection.
