The Hubei Provincial New Coronary Virus Infection Pneumonia Epidemic Prevention and Control Headquarters issued a notice on the 24th, clarifying the "unblocking" arrangements for the passage from Han to Hubei. However, two of the four newly diagnosed local cases reported nationwide the day before were related to Wuhan and Hubei. This leads to discussion: how to orderly "unblock"? How to prevent and control "careful end"?

Step by step to "unblock"

There are two “unblocking” time nodes in the official announcement issued by Hubei. First, starting at 00:00 on March 25th, the area outside Wuhan was deregulated from the control of the channel from Hubei, and external traffic was resumed in an orderly manner. Persons leaving Hubei had a safe and orderly flow based on the Hubei Health Code “Green Code”. Second, starting at 00:00 on April 8th, Wuhan City lifted the control measures for the Li-Er and Li-Eh passages and resumed external traffic in an orderly manner. The out-of-Han personnel moved safely and orderly with the Hubei Health Code "Green Code". The two time nodes differ by 14 days, which is equivalent to a medical isolation observation period.

Zhuo Jiatong, chief physician of Guangxi Centers for Disease Control and Prevention, and Zhang Xiao, a psychological counselor in Wuhan, said in an interview with a reporter from the China News Agency that the “unblocking” was aimed at the practical needs of returning to work and resuming production, and alleviating psychological pressure. It also has its objective basis. Judging from the latest situation, the spread of local epidemics nationwide, with Wuhan as the main battlefield, has basically been blocked. Recently, Wuhan has no new confirmed cases for 5 consecutive days.

"Step-by-step" unblocking "is more secure. The two time nodes are separated by 14 days, which is equivalent to setting a" examination period "buffer period." Chang Jian, a professor at the School of Government Management of Nankai University, told the reporter that in view of the new crown pneumonia epidemic Due to the particularity of the situation, a new situation may occur after "unblocking". Step-by-step "unblocking" will give people more time and conditions to solve problems beyond their expectations.

In addition to the announcement of "unblocking", Wuhan is also making various preparations for the transition from "wartime" to "peacetime". On the 23rd, more than 110 bus lines in Wuhan took the road for a test run. In recent days, many major urban construction projects including Jianghan Seven Bridge, Rail Transit Line 8 Phase II, and Dadonghu Deep Tunnel Project have resumed.

New cases need to be "tracked"

While cheering that Wuhan is about to "unblock", many people have noticed that sporadic cases and the risk of local outbreaks remain. Two of the four newly confirmed local cases reported on the 23rd were related to Hubei: 1 new confirmed case in Wuhan, and the patient was a doctor at the Hubei Provincial People's Hospital (Headquarters); 1 new case was imported from Guangdong, which is Foshan Reported Hubei imported cases.

"Individual phenomena need to be handled individually and will not affect the overall situation." Zhuo Jiatong raised the need to conduct epidemiological follow-up investigations on these cases. "In short, we must not only be more confident but also take it lightly."

Wang Guiqiang, chief physician of the Department of Infectious Diseases of Peking University First Hospital, also had a similar view in an interview with a reporter from China News Agency. "These two cases really remind us that the state of prevention and control cannot be relaxed." He analyzed that the possible reason for the infection of Wuhan doctors was inadequate protection. After all, front-line medical personnel are at great risk of infection, and any part of wearing protective clothing If there is a problem, there is a risk of infection. In response to Hubei imported cases reported in Guangdong, he proposed to follow up and "objectively and rationally treat new cases."

Chang Jian emphasized that people should change their concept from "absolute security" to "coexist with risks". Because from the perspective of the law of the virus itself, even if it is completely blocked, it is difficult to completely eliminate it. If long-term "coexistence" with the new crown virus, people need to take risk aversion, risk control and other management measures to ensure that the risk is within the controllable range, but the main goal is not affected.

Looking at the above-mentioned expert opinions, on the one hand, the contagiousness of sporadic cases or recessive infections has weakened; on the other hand, localities have certain reserves in terms of anti-epidemic materials, staffing, experience accumulation, and case tracking. It is not the same as the beginning of the epidemic.

After "Unblocking", "Be careful"

Zhang Xiao, who has been living in Wuhan during the epidemic, said that after "unblocking", the government still needs to regulate the catering, accommodation, and public transportation.

Chang Jian pointed out to our reporter that improper follow-up of disasters will also create new risks. For the current Hubei, especially Wuhan, the relevant departments need to relieve the public's negative emotions in a positive and scientific manner in a timely manner. They must also summarize and reflect on the epidemic situation in order to improve the system construction of the public health epidemic prevention system.

The outside world has noticed that the national and provincial aid and disease control teams of the Hubei Province have temporarily departed from Hubei. Wu Hao, the leader of the community prevention and control expert team of the work group in front of the National Health and Health Commission, explained that the E & D disease control team mainly undertakes two tasks, one is to prepare for resumption of work, including "emergency plan handling The second is to train related medical personnel and administrative personnel in Hubei Province. "Leave a disease control team capable of conquering wars to cope with future changes in the epidemic situation."

The official announcement issued by Hubei on the 24th also emphasized that all localities should further strengthen their territorial responsibilities, and do not relax and pay close attention to various prevention and control work, strictly prevent the increase in the flow of people and gathering to bring back the risk of epidemic rebound, and properly respond to imported risks. . It is necessary to make overall arrangements for the return of personnel stranded in Han and Hubei, and to refine the work arrangements to ensure a safe and orderly flow.

Some experts reminded that after "unblocking", Hubei nationality personnel must "walk out" and even "get in". Previously, there had been cases of "point-to-point" buses full of workers being blocked "outside the door" in provinces outside Hubei. People with Hubei ID cards also encountered discrimination in the process of recruitment and renting. To this end, all parties need to strengthen communication with Hubei and reach a two-way understanding.

On the 23rd, the Beijing side clearly stated that "we must proceed in an orderly manner to return to Beijing and conduct medical observations of detained Hubei personnel." There are also places where Hubei and Hubei mutually recognize the health code, or take the initiative to dock to help Hubei nationality workers return to work. (Finish)
