The spread of this round of the epidemic spreads again!

According to a report from the National Health Commission, 31 provinces (autonomous regions and municipalities directly under the Central Government) and Xinjiang Production and Construction Corps reported 43 new confirmed cases from 0-24:00 on October 25. Among them, 29 were local cases, mainly in Inner Mongolia and Gansu. And Ningxia.

It is worth noting that there has also been a local confirmed case in Shandong, which is also the 12th province to report a positive case in this round of the epidemic.

　　The epidemic still risks spreading

According to information released by Wulian County, Rizhao, Shandong, the confirmed case is a returnee from another province. I was active in Yinchuan, Ningxia on the 15th and 17th. On the 18th, I took the high-speed rail back to Rizhao from Yinchuan, and stayed in Rizhao for the next 6 days until I drove to the doctor on the 25th and was diagnosed with new coronary pneumonia (common type).

Obviously, the 6-day activity in Rizhao became a “window period” for the further spread of the virus. According to a local press conference on the 26th, the patient’s family of 4 members have tested positive for nucleic acid, of which 3 are confirmed cases and 1 is asymptomatic. Wulian County began to carry out nucleic acid testing for all employees on the 26th, and requires those who have overlapping temporal and spatial trajectories with confirmed cases, those who have been to or through medium- and high-risk areas, and those who accompanied them at the same time, to report personal information as soon as possible, and isolate them at home. Do not go out.

Coincidentally, among the 6 new local cases in Lanzhou, Gansu Province on the 25th, except for one who was a close contact of the previously confirmed case, the other 5 were all discovered in the second round of full-time nucleic acid testing in Lanzhou. This also suggests that there are still infected persons who are not yet under control.

Zhao Dahai, executive director of the Shanghai Jiaotong University-Yale University Health Policy Joint Research Center, said that from the current situation, the current round of the epidemic has not been completely controlled, and at least some of the infected cases have not been completely found. “Therefore, it is not ruled out. In the next 1-2 weeks, there will be related new local cases.”

　　Lock the Ejina Banner at the source?

At present, more than 200 cases of infection have been reported in this round of local epidemics. Except for a few cases, the transmission chain is still unclear, and the remaining infected people are directly or indirectly related to Ejina Banner, Inner Mongolia. As of 12:00 on the 26th, a total of 84 newly confirmed local cases in Ejina Banner has become the place with the largest number of confirmed cases in this round of the epidemic.

Ejina Banner is the flag with the largest area and the smallest population in the Inner Mongolia Autonomous Region. According to the seventh census, the permanent population of Ejina Banner is only more than 35,000, and only about 0.3 people per square kilometer. So, why did Ejina Banner, which is vast and sparsely populated, become the eye of the storm in this round of epidemic? Is it possible that the source of the epidemic is here?

According to a report from the Inner Mongolia Health Commission, in one day on October 25, Inner Mongolia reported two cases of confirmed cases of local coal-pull drivers. One of them is from Yijinhuoluo Banner, Ordos, and the other is a coal driver of an overseas coal sales and transportation company at Ceke Port, Ejina Banner. This is not the first time that Ceke Port has appeared in an epidemic notification.

On October 19, Lanzhou, Gansu issued a notice that a pedestrian from the Lanzhou tour group, Zhang, had visited Ceke Port on October 13. On October 21, a new case of nucleic acid test positive in Inner Mongolia was also involved in coal loading at Ceke Port.

According to the results of existing circulated and virus sequencing, the whole genome sequence of the virus in the case has low homology with the previous domestic epidemic, suggesting that this epidemic was caused by a new overseas import source. According to Zhao Dahai’s analysis, Ceke Port, as the only international channel opened by the Alxa League to the outside world, is also the country’s fourth continental road port. The Mongolian country it connects to is currently suffering from a serious epidemic. Therefore, Ceke Port may become the source of this round of epidemics. Larger.

Zhao Dahai said that it cannot be ruled out that Ejina Banner has already had a certain scale of hidden transmission. With the arrival of the golden autumn tourist season, local tour groups may be infected with the new crown virus in Ejina Banner, and then travel across provinces to spread the virus. To other provinces.

Chen Zhanyun, secretary of the Ejina Banner and Banner Committee of Inner Mongolia, was removed from his post on the 26th due to his due diligence and poor implementation in the prevention and control of the epidemic.

　　Strengthening shots still need to be given

Combining the currently published information on the circulation, we can find that the number of confirmed cases that are not directly related to tour groups is increasing, and the spread of the epidemic may further expand.

“This round of the epidemic reminds us that as long as the new crown epidemic has not disappeared from the earth, we should not be careless.” Zhao Dahai said that the public’s cross-regional travel will increase the risk of a rebound of the epidemic. To this end, we should advocate The public minimizes unnecessary travel and cross-regional movement. If it is necessary to travel, scientific prevention and control measures must be taken and not taken lightly.

In addition, Zhao Dahai also advised the public to vaccinate the new crown vaccine as much as possible. According to incomplete statistics, as of October 21, 17 provinces (autonomous regions and municipalities directly under the Central Government) including Beijing, Guangdong, Zhejiang, and Hubei have successively started the new crown vaccination booster vaccination.

However, a confirmed patient in Shijiazhuang said that he had been vaccinated with 3 doses of the new crown vaccine, but was still infected. This also caused some people to question the effectiveness of the booster. In Zhao Dahai’s view, the new crown vaccine is still an important measure to improve immunity and enhance self-protection at this stage. “Although the booster injection still cannot guarantee 100% of the vaccinated people will not be infected by the new crown virus, it can at least further reduce the risk of infection,” Zhao Dahai said.
