Original title: This round of the epidemic spread to 9 provinces in 4 days, and Beijing took the lead in announcing the progress of virus traceability
From October 17 to 20, the current round of the epidemic that began with the “elderly tour group” has infected 38 people.
The reporter found that compared with the past, most of the local epidemics were fermented locally and spread more concentratedly. A major feature of this round of epidemics is that they spread rapidly across provinces within a few days. In the four days, 9 provinces including Shaan, Gansu, Mongolia and Ning were involved. Today, another positive person was detected in Qinghai.
Up to now, the “elderly tour group” discovered in Xi’an and the Lanzhou tour group have extended two clearer transmission chains, and Beijing, which is in the middle of the chain, has taken the lead in publishing the sequencing results. However, among the newly infected people, there is no clear “upstream” close connection.
The traceability of the epidemic is still in progress.
Fermentation affects 9 provinces in 4 days
The cases are mostly concentrated in “Shanxi, Gansu, Ningxia and Mongolia”
According to statistics, 38 infected people are distributed in 9 provinces in China, including Shaanxi, Gansu, Inner Mongolia, Ningxia, Hunan, Beijing, Hebei, Guizhou, and Hubei. Among them, the infected were found in Lanzhou and Zhangye cities in Gansu, and Yinchuan and Wuzhong cities in Ningxia.
The nucleic acid-positive person was first discovered in Jiayuguan, and the patient was diagnosed in Xi’an, Shaanxi Province because the patient was traveling. Up to now, 8 infected persons have been found in Xi’an, 7 members of the tour group and 1 member of the same tour group. The relationship is clear.
The number of infected persons in Gansu showed an increasing trend in the later period. According to information from the National Health Commission, Lanzhou notified 6 infected persons for the first time on the 19th. On the 20th, Lanzhou and Zhangye reported 4 cases and 1 confirmed case respectively (1 person had an asymptomatic outcome). The total number of infected persons in Gansu reached 10.
Most of these 10 people have traveled together, traveling in Zhangye, Jiayuguan, and Alxa League in Inner Mongolia. After returning from the trip, the father, son, and colleagues had close contact with each other, causing secondary transmission. The Gansu tour group has similar travel records with the original “elderly tour group”, such as visiting the scenic spots of Colorful Danxia and Populus euphratica, and having dinner at the same restaurant at the same time.
This restaurant, called Tongnan Pavilion, once became the focus of attention from the outside world. The 5 positive persons found in Inner Mongolia were all restaurant employees.
The Ningxia epidemic is also inextricably linked with tour groups. Among the two infected persons announced by Yinchuan, one was in direct contact with the elderly tour group, and one had space to intersect with the close contact; the three infected persons in Wu Zhong had the same itinerary or were a travel group departing from Zhejiang.
Fewer infected people have been detected in other provinces. Some transmission chains are extended by the two tour groups mentioned above and spread to other provinces.
Viral gene sequencing announced for the first time
“Delta” again, spreading in 5 provinces
On October 19, a close contact in Fengtai, Beijing took the initiative to report, and was subsequently diagnosed. On the 21st, Beijing was the first to announce the results of virus gene sequencing: Delta again.
Pang Xinghuo, deputy director of the Beijing Centers for Disease Control and Prevention, said that the variant strain has low homology with the virus genomes of previous local and imported cases in Beijing. After preliminary comparison and analysis by experts from the China Centers for Disease Control and Prevention, the results show that it is similar to the recent results of Gansu, Shaanxi, etc. The cases reported locally have high virus homology and belong to the same chain of transmission.
This transmission chain can be clearly traced to the other 4 provinces.
The Beijing case is directly related to the Ningxia Yinchuan case Ai Moumou, which can be traced back to the “elderly tour group”. According to the Beijing Municipal Disease Control and Trends Report, on October 16th, the patient travelled with Ai Moumou in an adjacent sleeper. On the same day, Ai just finished the trip with the tour group and returned to Yinchuan from Jiayuguan by car.
The Hebei epidemic is also linked to Beijing. After Beijing conducted a circulation survey on the first confirmed person, 9 close contacts were locked, and the information of 3 persons was transferred to Hebei. Yesterday, 2 of them were determined to be positive.
From Inner Mongolia and Gansu to Ningxia, Beijing, and Hebei, this transmission chain spans five provinces geographically, covering a triple close relationship.
One member of the Gansu tour group traveled across provinces, and Changsha, Hunan was also “involved” in this round of the epidemic. At present, two infected persons have been found in Changsha, one person had been close to a tour group, and one person was on the same flight as the close one. However, the two are not in the same row and three rows in the same ride. The latter has also traveled in Yinchuan in Ningxia, Ejina Banner in Inner Mongolia, and Zhangye in Gansu.
The scope of the epidemic has expanded
Individual cases “upstream” unknown
At present, the epidemic has entered its fifth day, and new infections continue to appear, and the scope of the epidemic is also expanding.
On the 21st, the New Crown Pneumonia Prevention and Control Headquarters of Ejina Banner in Inner Mongolia issued Announcement No. 18. Following the diagnosis of 5 restaurant employees, 8 more confirmed cases were found in the local staff test today. Zuoqi, also a member of the Alxa League, found a positive result of a mixed inspection tube yesterday, and then reviewed one person for infection.
In the early morning of the 21st, the Center for Disease Control and Prevention of Pingan District, Haidong City, Qinghai Province also reported a positive person. The person took the D2746 train to Lanzhou West Station on October 15 and returned to Haidong on October 17.
At present, the close connection status of some cases is unknown.
The four infected persons in Tianmen, Hubei and Zunyi, Guizhou, the official census only introduced that they had visited the Ejina Banner of the Alxa League in Inner Mongolia, Jiuquan, Gansu, Zhangye and other places, without mentioning when and where they had been with the previous infected person. Have had contact. Among them, the second person infected in Guizhou did not mention that they had been to Gansu and Inner Mongolia in the information.
The infected people in the Alxa League Left Banner also have no clear “upstream”. He did not travel in scenic spots such as Zhangye, Jiayuguan, Ejina Banner, etc., which is different from the travel routes of most infected people. The closest location was when I arrived at the exit of Ejinaqi Expressway on the evening of October 15 and stayed in the car. Afterwards, he passed the Ejina Qi gas station, Yagan service area, restaurant, etc., but did not enter the scenic spot.
