This round of the epidemic transmission chain spreads again!
According to the National Health Commission, at 0-24:00 on October 25, 31 provinces (autonomous regions and municipalities directly under the Central Government) and the Xinjiang Production and Construction Corps reported 43 new confirmed cases, of which 29 were local cases, mainly concentrated in Inner Mongolia, Gansu and Ningxia.
It is worth noting that there is also a locally confirmed case in Shandong, which is also the 12th province and region in this round of epidemic to report a positive case.
There is still a risk of spreading the outbreak
According to the news released by Wulian County, Rizhao County, Shandong Province, the confirmed case is a returnees from other provinces. On the 15th to the 17th, they were all active in Yinchuan, Ningxia, on the 18th, they returned to Rizhao by high-speed rail, and then they have been active in Rizhao for the next 6 days, until they drove to the hospital on the 25th, and were diagnosed with new crown pneumonia (ordinary type).
Obviously, the 6-day activity in Rizhao has become a "window period" for the further spread of the virus. According to the local press conference on the 26th, at present, the patient's family of 4 families have nucleic acid tests positive, of which 3 are confirmed cases and 1 is an asymptomatic infected person. Wulian County began to carry out nucleic acid testing for all employees from the 26th, and required personnel who have recently overlapped with the spatio-temporal trajectory of confirmed case activities, personnel who have been to or passed through medium- and high-risk areas, and accompanying personnel at the same time, to report personal information at the first time and not to go out in home isolation.
Coincidentally, among the 6 new local cases in Lanzhou, Gansu Province, on the 25th, except for 1 case that was a close contact of the previously confirmed case, the other 5 were found in the second round of nucleic acid testing in Lanzhou. This also suggests that there are still infected people who are not under control.
Zhao Dahai, executive director of the Shanghai Jiao Tong University-Yale University Joint Research Center for Health Policy, said that from the current situation, the current round of the epidemic has not been completely controlled, at least some of the infected cases have not been fully found, "therefore, it is not excluded that in the next 1-2 weeks, there will be associated new local cases."
Source lock Ejina Banner?
At present, the cumulative number of infected people reported in this round of local epidemic has exceeded 200, except for a few cases whose transmission chain is not clear, the rest of the infected people are directly or indirectly related to Ejin Naqi in Inner Mongolia. As of 12:00 on the 26th, Ejin Naqi has accumulated 84 new local confirmed cases, which has become the place with the largest number of confirmed cases in this round of epidemic.
According to the data of the seventh census, the permanent population of Ejina Banner is only about 35,000 people, and only about 0.3 people per square kilometer. So, why did the sparsely populated Ejin Banner become the eye of the storm in this round of epidemics? Is it possible that the source of the epidemic is here?
According to the Inner Mongolia Health Commission, within one day of October 25, Inner Mongolia reported the news that two local coal drivers were confirmed. One of them is from Yijin Holo Banner in Ordos, and the other is a coal transport driver of a coal sales and transportation enterprise engaged in overseas coal sales and transportation at the Ceke port of Ejina Banner, which is not the first time that the Ceke port has appeared in the epidemic notification.
On October 19, Gansu Lanzhou issued a notice that a member of the Lanzhou tour group Zhang Mou and his party had visited the Ceke Port on October 13. On October 21, a new positive nucleic acid test case in Inner Mongolia had also participated in coal loading at the Ceke port.
According to the existing flow adjustment and virus sequencing results, the whole genome sequence of the virus in the case is low in homology with the previous epidemic in China, suggesting that the epidemic was caused by a new source of import from abroad. According to Zhao Dahai's analysis, ceke port, as the only international channel opened to the outside world by the Alxa League, is also the fourth largest land road port in the country, and the Mongolia it connects to is currently seriously affected, so it is more likely that ceke port will become the source of this round of epidemic.
Zhao Dahai said that it is not excluded that there has been a certain scale of hidden transmission in Ejin Naqi before, and with the arrival of the golden autumn tourist season, local tour groups may have been infected with the new crown virus in Ejin Naqi, and then spread the virus to other provinces through inter-provincial movement.
Due to the performance of duties and poor implementation in the epidemic prevention and control work, Chen Zhanyun, secretary of the Inner Mongolia Ejin Banner Committee, was dismissed from his post on the 26th.
The reinforcement needle is still to be shot
Combing through the currently released circulation information, it can be found that the number of confirmed cases that are not directly related to the tour group is increasing, and the scope of the epidemic may be further expanded.
"This round of the epidemic has given us a wake-up call, that is, as long as the new crown epidemic has not disappeared from the earth, we must not be careless," Zhao said, the public's cross-regional tourism will increase the risk of rebound, so we should advocate that the public minimize unnecessary travel and cross-regional mobility. If you must travel, you must take scientific prevention and control measures, and you cannot take it lightly.
In addition, Zhao Dahai also recommended that the public receive the new crown vaccine as much as possible to strengthen the injection. According to incomplete statistics, as of October 21, 17 provinces (autonomous regions and municipalities directly under the central government) such as Beijing, Guangdong, Zhejiang and Hubei have successively opened the vaccination of new crown vaccination and reinforcing injections.
However, before that, a confirmed patient in Shijiazhuang said that he had received 3 doses of the new crown vaccine, but he was still infected, which also made some people question the effectiveness of the booster needle. In Zhao Dahai's view, the new crown vaccine is still an important measure to improve the level of immunity and enhance self-protection at this stage. "Although the reinforcing needle still cannot guarantee that 100% of the vaccinated people are not infected by the new crown virus, it can at least further reduce the risk of infection," Zhao said.
