[Today I had dinner with the director. I just finished it and I got home a little late. I really didn't let me go on the day of rest. 610 will be modified at around one o'clock. You can wait or watch it tomorrow morning]

On June 14 and 18, Shenzhen reported 3 new confirmed cases of ****. Last night, the Shenzhen Municipal Government Information Office held a press conference to report the latest progress of the epidemic.

Shenzhen Vice Mayor Tao Yongxin introduced that the epidemic is currently under control and the risk of large-scale spread is relatively low.

At around 20 pm on June 18, Shenzhen Bao'an turned over the area, and citizens lined up for nucleic acid testing.

Bao'an International Airport

More than 50,000 employees tested negative for nucleic acid

According to the website of the National Health Commission, from 0:00 to 24:00 on June 18, my country added 6 new local infection cases, all in Guangdong Province. Including 2 cases reported in Guangzhou, 2 cases reported in Shenzhen, 1 case reported in Foshan, and 1 case reported in Dongguan.

Late at night on June 18, the Shenzhen Municipal Health Commission reported the details of 2 new confirmed cases:

Case 1: Xiao, male, 35 years old, an employee of a company in Block A, Houhai Aerospace Science and Technology Plaza, Nanshan District, living in Baiyue Shangcheng Community, Nancheng District, Dongguan City. On June 18, the Shenzhen Center for Disease Control and Prevention was reviewed positive and diagnosed as a **** confirmed case (normal type). According to public information, the activity trajectory before the report was positive involves the airport transportation center.

Case 2: Zhu, female, 21 years old, a waiter at a restaurant at Bao'an Airport in Shenzhen, lives in Xinlantian Apartment, No. 71, Xiashiwei Commercial and Residence Street, Fuyong District. On June 17, the nucleic acid test was positive in the key population investigation. The next day, the Municipal Center for Disease Control and Prevention reviewed positive and was diagnosed as a **** confirmed case (mild). Dongguan reported that 1 new confirmed case was: Li Mouting, female, 30 years old, lives in Baiyue Shangcheng Community, Nancheng District. The confirmed case was **** (mild symptoms), and the current situation is stable. The activity track shows that he had visited hospitals, childcare centers, restaurants, convenience stores and other places many times before the diagnosis. The investigation said that Li Mouting and Shenzhen case 1 Xiao Mou were married.

At present, Building 2, Baiyue Shangcheng Community, Nancheng Street, Dongguan City, where Xiao and Li Ting are located, and Xinlantian Apartment, No. 71, Xiashiwei Commercial and Residence Street, Fuyong Street, Bao'an District, Shenzhen, where Zhu lives, has been adjusted to a medium-risk area.

Tao Yongxin introduced that Shenzhen has quickly launched emergency responses for three confirmed cases in Xiao’s workplace, the staff of Building A of the Aerospace Science and Technology Plaza, residents of the residence and individual cases 2 of Bao'an International Airport, where Zhu worked, were nucleic acid tests for all employees, all of which were negative. All those who have been to Shenzhen Airport since June 10 were conducted on-site inspections and nucleic acid tests were carried out. The nucleic acid tests were organized for Zhu and Xiao’s activity trajectory, and the test results were negative.

There is a correlation between the two staff members at Shenzhen Airport.

Related flights have been "fuseless"

Among the two new confirmed cases in Shenzhen, two cases have attracted great attention.

On June 18 and 19, the Shenzhen Center for Disease Control and Prevention completed the gene sequencing of the new coronavirus by Zhu and Xiao. The virus carried by the two was highly homologous to 16 positive cases imported from CA868 international flights and the confirmed case reported on June 14, both of which were Delta variants (B.1.617.2).

Based on the epidemiological investigation, the results of nucleic acid testing and virus gene testing were initially judged that this epidemic is a **** epidemic related to imported cases from abroad.

Flight CA868 took off from Johannesburg, South Africa. As of 24:00 on June 15, 32 positive cases of imported cases from abroad have been found on Flight CA868, which arrived in Shenzhen on June 10. Jiang is a staff member of Bao'an Airport, responsible for the epidemiological investigation of incoming passengers on the flight. After viral gene sequencing, Jiang was determined to be a related case of a flight to Shenzhen on June 10. On June 18, Zhu, a case 2, was confirmed as a key group of people in the investigation. Air China's CA868 flight was "circuited" on June 16 and was suspended for 4 weeks.

Jin Dongyan, a well-known virology expert and professor at the School of Biomedical Sciences of the University of Hong Kong, told the "medical community" that the two airport staff were diagnosed continuously, and the virus gene sequencing was completely consistent, indicating that there is an association between cases and it is likely to belong to the same transmission chain.

The "medical community" learned that Jiang's work scope is in the area of ​​international flight entry and exit, and Zhu's restaurant is located in the west track corridor of the airport terminal, mainly serving domestic passengers. It is not clear how Zhu's infection is.

On June 17, Li Jian, deputy general manager of Shenzhen Airport Co., Ltd. and deputy director of the Airport Prevention and Control Office, said in an interview with Shenzhen Satellite TV that Shenzhen Airport adopts a full-process closed-loop management for overseas passengers coming to Shenzhen. Passengers who take international flights to Shenzhen will undergo nucleic acid testing after getting off the plane and then directly sent to the quarantine hotel. International flight personnel will not cross the passengers on domestic flights. Non-flight crew members are also strictly closed-loop management. From the beginning of entry, a dedicated person will be sent to the crew's centralized rest area at two points and one line. They cannot go out when they do not perform tasks.

In response to the recent epidemic, Shenzhen Airport said that it has made special efforts to distinguish staff from various aspects into high-risk, medium-risk and low-risk personnel. High-risk personnel live in two points and one line at the same time, undergo health checks every day, and undergo nucleic acid tests every two days.

Staff from Shenzhen Airport and airlines said in an interview that many people have collected nucleic acid samples several times in June. In order to strengthen protection, some front-line positions have been required to wear protective clothing.

Strengthen research and make decisions as soon as possible

How to "get the third shot of the vaccine"

According to Caixin, its reporter learned from people close to Shenzhen Airport that the confirmed Zhu has received the new crown vaccine.

Professor Jin Dongyan pointed out that this reminds us that front-line staff with exposure risks should keep ringing alarms, and protection awareness and measures should not be relaxed. "Vaccines are not 100% of the protection of the new coronavirus. In this round of epidemic in Guangzhou, we have also seen confirmed cases infected with the Delta mutant strain after receiving the new coronavirus vaccine."

The Delta mutant strain first appeared in India. From May 21 to 24:00 on June 18, Guangzhou reported a total of 153 local infections in this round of epidemic in Guangzhou, and some have been confirmed to be related to infection with the Delta mutant strain. "The mutant strain has the characteristics of short incubation period, fast transmission speed and high viral load." On May 31, Zhang Zhoubin, deputy director of the Guangzhou Center for Disease Control and Prevention, said at the epidemic prevention and control press conference that the fast transmission speed and strong transmission power are the biggest difference between this round of epidemic and previous epidemics. "It is reflected in the fact that a short and indirect contact can cause transmission by eating a meal."

After receiving the vaccine, the infection is called a "breakthrough infection". Cai Weiping, chief expert of the Infectious Disease Center of Guangzhou Eighth People's Hospital, said that there are three reasons: First, for some people, the vaccine may not stimulate enough immune system response; second, the immune system may not have enough time to produce necessary antibodies to resist infection; third, it may infect mutant strains that partially or completely bypass the vaccine. However, even if a breakthrough infection occurs, vaccination can reduce the incidence of severe illness and death after infection.

On the 18th, the official WeChat account of Nanshan District Center for Disease Control and Prevention in Shenzhen published a post saying: "Virus evolves, and residents' protection must also evolve." The article pointed out that the Delta mutant strain occurs quickly after infection, and the number of young people among critically ill patients increases.

Yang Xingfen, dean of the School of Public Health of Southern Medical University, pointed out that the characteristics of the Delta mutant strain have been reminding us that as long as there is a slight slack, the epidemic will be at risk of rebound. At this stage, personal protection should be "two as soon as possible". The first is to get the new coronavirus vaccine as soon as possible, which will help establish an immune barrier and protect the health of more people. The other is to monitor self-health. If there are symptoms such as fever, dry cough, fatigue, sore throat, loss of smell (taste), diarrhea, etc., you must go to the fever clinic as soon as possible to achieve early detection and early diagnosis.

Professor Jin Dongyan said that it is still unknown whether the breakthrough infection will increase significantly against the Delta mutant strain. He reminded that vaccine research and development and production companies should strengthen research. On the one hand, they should develop vaccines with higher protection. On the other hand, they should decide as soon as possible whether and how to "get the third shot of the new crown vaccine" for high-risk groups to further improve the immunity level of key groups to the new crown.

People are confident in escalating epidemic prevention

At present, Shenzhen and Dongguan have issued consecutive notices, and epidemic prevention measures are constantly being upgraded.

Interface News, Caixin and other reports that Shenzhen Airport had carried out emergency response work on the 18th, closing all shops in the terminal, and the third round of nucleic acid testing for all employees at the airport. In case 2, the 56 airport employees who were dining in the restaurant Zhu worked in the restaurant are in quarantine.

"Shenzhen Release" news, from June 19, the cross-city passenger routes of Shenzhen Airport Bus Station will be suspended, and the recovery time will be notified separately. From 13:00 on the same day, all personnel entering the Shenzhen Airport terminal (including the ground transportation center) must issue a negative nucleic acid test certificate within 48 hours based on the existing temperature measurement and "health code" inspection, otherwise they will not be able to enter the terminal and other areas.

According to the WeChat official account of the Dongguan Municipal People's Government Information Office, starting from now on, citizens who do not leave Dongguan and do not leave the province unless necessary, and who really need to leave Dongguan and the province must hold a negative nucleic acid test certificate within 48 hours. In addition, the entrance of the Dongguan Expressway will conduct epidemic prevention inspections on vehicles and personnel leaving Dongguan. From 19:30 on the 18th, control measures will be taken for all vehicles at the intersection of Dongcheng, Nancheng, Wanjiang, Mayong and other towns, streets, and only enter and not leave. From the 19th, the Dongguan City Terminal will suspend all trips to and from Shenzhen/Guangzhou at all stations, and will be notified separately on the date of resumption.

In addition, closed management measures were taken in many regions of the two places.

Dongguan has adopted closed management measures for 13 key areas with active trajectories of suspected cases, closing entrances and exits, and personnel do not leave their homes. Residential communities within 2 kilometers of the surrounding area are controlled by the closed management area, and personnel only enter and do not leave. China News Service reported that on the afternoon of the 19th, news came from the Dongguan Municipal Center for Disease Control and Prevention that the first round of nucleic acid tests in 13 key closed areas were negative. At the same time, Dongguan City conducted a comprehensive nucleic acid test on five towns and streets, including Guancheng, Dongcheng, Wanjiang, Nancheng and Mayong, and the testing work is still in progress.

Ms. Chen (pseudonym), who lives in Shenzhen, told the "medical community" that as far as she knows, those who have found close contacts or second-quarter contacts in many communities in Shenzhen have issued home isolation notices, and the Houhai Metro Station in Nanshan District has also been blocked.

On the afternoon of June 18, the "Shenzhen Metro" posted a Weibo post saying that the entrance and exit of Houhai Station J is temporarily closed.

A Ms. Wang (pseudonym), who lives in Bao'an District and works in Nanshan District, told the "medical community" that in late May, after positive cases occurred in Yantian District, Shenzhen and Longgang District, Shenzhen, many districts in Shenzhen organized nucleic acid tests every week. On June 8 and 16, she received two nucleic acid samples respectively.

Ms. Chen has also completed two rounds of nucleic acid tests. "Now, it is really fast to do nucleic acid. Scan the code to fill in the information, and the doctor will not stop taking the sampling."

Ms. Chen believes that considering the frequency of nucleic acid testing, coverage of the population, vaccination rate and epidemic prevention efforts, Shenzhen should be able to control the situation soon.
