According to the World Health Organization, the delta mutant strain is currently the most important mutant strain of the new coronavirus. This strain first occurred in India, and its transmission capacity has been significantly enhanced, and it is becoming the major global epidemic of the new coronavirus mutant. According to the previous report from the Nanjing Centers for Disease Control and Prevention, it was the Delta mutant that triggered the cluster outbreak at Nanjing Lukou Airport; after gene sequencing, the first two infected persons in this round of Zhengzhou entered the country with Myanmar and were treated at the Sixth Hospital of Zhengzhou City. The virus strains of the confirmed patients are highly homologous, all of which are delta variants.
As of 21:00 on August 8, there are 15 high-risk areas across the country, distributed in 4 provinces-Yunnan (1), Jiangsu (3), Henan (8), Hunan (3); there are 201 medium-risk areas, distributed In 13 provinces (regions and cities)-Beijing (2), Yunnan (4), Jiangsu (116), Sichuan (5), Liaoning (1), Hunan (25), Fujian (2), Henan (33) , Hubei (6), Shandong (3), Shanghai (1), Hainan (2), Inner Mongolia (1).
Sun Chunlan, member of the Political Bureau of the CPC Central Committee and Vice Premier of the State Council, went to Zhengzhou City, Henan Province to investigate and guide the prevention and control of the epidemic after the national teleconference on the prevention and control of the new crown pneumonia epidemic on August 4. She emphasized that it is imperative to implement prevention and control measures and contain the spread of the epidemic as soon as possible.
The fierce attack on Delta once again sounded the alarm for the prevention and control of the epidemic, and also put forward higher requirements for the prevention and control work. The State Council’s Joint Prevention and Control Mechanism Comprehensive Team has dispatched 20 working groups to supervise key port cities to check and plug loopholes, strengthen foreign defense imports and handle emergencies.
“Delta” is coming fiercely, and vaccines are still “the only magic weapon”
At the State Council’s Joint Prevention and Control Press Conference held a few days ago, He Qinghua, the first-level inspector of the CDC of the National Health Commission, introduced that the Delta strain has the characteristics of fast spreading, fast replication in the body, and long time to turn negative.
The Guangzhou police, responsible for assisting in epidemiological investigations, once released a surveillance video: In the same restaurant, the third-generation infected person Huang and the fourth-generation infected person Lu went into the bathroom one after another. Without any physical contact, The virus spread in 14 seconds. In the Guangdong epidemic in June, there were cases of infection in the fifth and sixth generations in just 10 days.
On August 7, the press conference on the prevention and control of the new crown pneumonia in Zhengzhou, Henan Province announced that a confirmed case only showed positive results at the 8th nucleic acid test. “This case fully demonstrates that the delta mutant virus has the characteristics of high infectivity, high concealment, and atypical initial symptoms. It puts forward higher requirements for detection, discovery, and reporting. It is necessary to promote nucleic acid testing in multiple rounds as soon as possible. Achieve the periodic bottoming out of virus-infected people.” said Li Huifang, deputy secretary-general of the Zhengzhou Municipal Government.
After being infected with the delta mutant strain, the onset is rapid and the fever is prone to be high. On August 7, at a press conference on the prevention and control of the epidemic in Beijing, Liu Qingquan, a member of the New Coronary Pneumonia Treatment Expert Group of the National Health Commission and Dean of Beijing Hospital of Traditional Chinese Medicine Affiliated to Capital Medical University, introduced that from the perspective of Chinese medicine, the delta variant strain The disease caused by the disease and the disease caused by the new crown pneumonia in the winter and spring of 2020 are both wet and poisonous. It is just that the disease caused by the delta variant that onset in the summer is also mixed with “heat evil.” From the clinical symptoms, the onset is rapid and it is more likely to have high fever.
“Relevant scientific research and epidemic prevention and control practices at home and abroad have shown that the Delta mutant strain has not led to subversive changes in the biological characteristics of the new crown virus. The source of infection and the transmission route are basically clear. The existing epidemic prevention and control measures have affected the Delta mutant strain. Still effective. Existing vaccines still have good preventive and protective effects, can reduce the risk of virus transmission in the population, reduce the transmission power of infected persons, and effectively reduce the incidence of severe illness and mortality after infection.” He Qinghua said.
Multi-departmental upgrade management and control measures, working together to “guard the line of defense”
This round of the new crown pneumonia epidemic first occurred at Nanjing Lukou International Airport. Han Guangzu, deputy director of the Flight Standards Department of the Civil Aviation Administration, said at the joint prevention and control press conference, “The reasons are many, including the inadequate implementation of prevention and control systems. The smooth operation of time has caused airport employees to have a relaxed and paralyzed mentality, as well as the outsourcing of airport cleaning services, and the failure to strictly implement the responsibilities of epidemic prevention and control.”
Han Guangzu introduced that for weak links, the Civil Aviation Administration encrypts the frequency of nucleic acid testing for all front-line staff, and front-line staff engaged in international business require nucleic acid testing on the next day, which will be arranged in turn according to the situation. Other service guarantee personnel must perform nucleic acid testing twice a week, with an interval of more than two days. That is to do one test two days and two tests a week for different risk personnel.
In addition to airports, ports, designated hospitals, and other places have also experienced cases of overseas imported cases, which have caused a certain range of spread.
Li Huaqiang, deputy director of the Department of Transportation of the Ministry of Transport, said that the Ministry of Transport instructs all localities to adopt relatively fixed and fixed personnel for the first-line positions such as drivers of international road cargo transport vehicles, crews on boarding ships, pilots, and import cold chain cargo handlers. Shift system, centralized accommodation and other measures to avoid contact with family members and community members. At the same time, instruct all localities to increase the frequency and frequency of nucleic acid testing for front-line personnel of entry and exit transportation at roads and waterway ports. For high-risk personnel, nucleic acid testing can be carried out every other day, and the remaining front-line personnel can be tested twice a week, each time. More than two days apart. For ship crews from countries and regions with severe epidemics, strict port management and crew shift management are required.
Delta mutant strains are more infectious, which brings greater challenges to the normal operation of high-speed trains, high-speed trains and other vehicles with high mobility.
Wu Shiping, deputy director of the Labor and Health Department of the National Railway Group, emphasized at the joint defense and joint control press conference that people who do not meet the travel requirements should be resolutely prevented from entering the station and boarding the train. In accordance with the capital’s epidemic prevention and control requirements, the sale of tickets for entering Beijing in medium and high risk areas such as Nanjing and Zhengzhou has been suspended. Introduce free refund measures to guide passengers to rationally arrange their itineraries, reduce the flow of people, and reduce the risk of epidemic spread. At the same time, quarantine seats have been set up on the trains. In the event of feverish passengers, they will be isolated and disinfected in time and handed over to the local epidemic prevention department.
What the people need to do to face “Delta”
At present, the epidemic is spreading in many places in the country, and the summer travel peak is superimposed. The risk of the spread of the epidemic is increasing. How can the masses take precautions?
First of all, we must continue to do personal protection. He Qinghua said that some time ago, my country successfully blocked the local epidemic of delta variants that occurred in several cities in Guangdong Province, which is densely populated and highly mobile, and proved that vaccination, wearing masks, washing hands frequently, and maintaining social distance, Measures such as avoiding crowds are effective.
Reducing cross-border movement is also an effective measure to prevent and control the epidemic. At the joint prevention and joint control press conference, Liu Haitao, Director of the Border Inspection and Management Department of the Immigration Bureau, introduced that since the global pandemic, the National Immigration Administration has strictly issued ordinary passports and other entry and exit documents for citizens. Arrangements for travel abroad have been postponed, and the number of people entering and leaving the country has been greatly reduced, effectively preventing the risk of infection. The Immigration Bureau will continue to implement strict management policies and measures.
He said that applications for overseas study, employment, business, etc., who have real needs, will be processed in a timely manner, and the entry documents will be issued after verification. For Chinese citizens who participate in the international epidemic prevention and anti-epidemic and who need to enter and exit due to the resumption of work and production of enterprises, the Immigration Bureau will promptly accept the examination and approval or provide expedited services. If the parties encounter problems, they can call the 24-hour service hotline of the “12367” national immigration management agency.
Previously, the chess and card room became the “tipping point” of the epidemic in Yangzhou. According to a report from the Jiangsu Provincial Health Commission, of the 16 confirmed cases of new coronary pneumonia in Yangzhou on July 31, 15 have been to the chess room to play cards. At present, KTVs, chess and card rooms and other indoor confined places in Beijing, Guangzhou and other places are all “closed”.
As of August 4, 1152 A-level tourist attractions in 20 provinces (autonomous regions and municipalities) across the country have been suspended in accordance with local epidemic prevention and control requirements. More than 90% of 5A-level tourist attractions in the country have basically realized time-sharing appointments. The 31 provinces (autonomous regions, municipalities) and Xinjiang Production and Construction Corps temporarily closed 256 public libraries, 236 cultural centers, and 6,757 cultural stations. National cultural and tourism activities sponsored by the Ministry of Culture and Tourism have been postponed or changed to online.
Yu Changguo, deputy director of the Market Management Department of the Ministry of Culture and Tourism, reminded the general public: Strictly abide by the epidemic prevention and control regulations and do not travel to medium- and high-risk areas. Tourists already in high-risk areas must strictly abide by the local epidemic prevention and control requirements and actively cooperate with the epidemic prevention and control work. Residents in high-risk areas should not travel. “Everyone must strengthen personal protection, stay vigilant, consciously keep a distance from other tourists when taking transportation and sightseeing, and open the table and chairs when eating to avoid getting together. When coughing or sneezing, pay attention to cover with elbows or tissues. Do not spit anywhere. When symptoms such as colds and fever occur, stop visiting and seek medical attention in time.”
