On July 23, at the press conference of the epidemic prevention and control work held by the Chengdu Municipal People's Government's Press Office, Fan Shuangfeng, director of the Emergency Office of the Chengdu Center for Disease Control and Prevention, introduced that on July 22, Chengdu added an exception to the case of Rong Rong. This case 7 On the 18th, it was exposed to a local case with a new crown pneumonia on the 18th. In the early morning of July 21, I drove to Rong Rong. There was a certain event. In the afternoon, I participated in the sampling of the mixed pipes to be inspected. In the early morning of the 22nd, the feedback was abnormal. It was immediately incorporated into isolation control. On the same day, the single nucleic acid test was positive.

After the "7.22 epidemic", Chengdu launched a flow traceability and personnel inspection and control. As of 14:00 today, a total of 1,182 people were investigated and 1063 were connected. More than 830,000 nucleic acid testing has been completed. Except for the reported positive cases, the rest are negative. At present, the secrets and sub -secrets that have been found have been incorporated into isolation control.

The gene sequencing of the first case of the epidemic in July 22 has been completed. As a result, the Omikon mutant plant BA.2.38 has been highly the same as the recent domestic epidemic virus sequences in other cities in China. Combined with epidemiological surveys found that the case of this case has a history of the same space with patients with new crown pneumonia, and the source of this epidemic infection is clear. According to the current current progress and sequencing results, it is clear that the 7.22 epidemic and the 7.15 epidemic are two independent communication chains, which are not related to each other.

Due to the strong spread of Omikon BA.2.38, it has caused a large -scale epidemic in many places in the country. After the case, the business company and the logistics park have stayed for a long time. The above -mentioned areas are densely personnel places, which has caused renewal cases. The positive infection will still be detected in close contacts in the future.
