At the above-mentioned press conference, Mao Genhong, deputy secretary general of the Hangzhou Municipal People's Government, introduced that 54 cases in the past 5 days were found in the centralized isolation point. Cases have been reported in the last two days in single digits. In terms of the number of cases, the inflection point has emerged.
"According to comprehensive analysis, the current round of the epidemic has achieved zero in the community." Mao Genhong said that the epidemic prevention and control work has shifted from community clearance to the work stage of zeroing out isolation points.
The epidemic spread at the 297-person annual corporate meeting
It seems that the epidemic prevention and control war in Hangzhou has been fought relatively quickly, and in fact, it is quite difficult.
The first case of the epidemic in Hangzhou is an employee of Hangzhou Binjiang Huierte Company. The case became ill on the afternoon of 21 January, took the initiative to seek medical treatment at noon on the 25th, initially screened positive at 22:00 on the same day, and was confirmed in the early morning of 26 January. That said, the outbreak had been circulating for almost a week since its discovery.
On the afternoon of January 26, a press conference on the prevention and control of the new crown pneumonia epidemic in Hangzhou said that the virus sequence infected by case Gan X was highly homologous with the virus sequence uploaded in a country abroad on December 11, 2021, which indirectly confirmed that the strain came from abroad and had nothing to do with the previous epidemic situation in China.
During the nearly one-week insidious spread of the virus, crowd gathering activities such as corporate annual meetings and wedding banquets have brought a certain amplification effect to the spread of the epidemic.
It is reported that Huierte Catering Equipment Co., Ltd. held an annual meeting of 297 people on the afternoon of January 19; after the annual meeting of the enterprise, many employees returned home on vacation, which spilled over the epidemic; on January 22, many high-risk personnel participated in a wedding of 244 people...
"Judging from this, the number of infected people in this epidemic should reach double digits." Li Huanlong of the Fuyang District Center for Disease Control and Prevention in Hangzhou said on January 26 through an article on his WeChat public account.
"The outbreak is mainly concentrated in the riverside area, showing a dotted sporadic and local cluster." On the afternoon of January 29, the Information Office of the Zhejiang Provincial Government held the 102nd press conference on the prevention and control of the new crown pneumonia epidemic, and Xia Shichang, deputy director of the Office of the Leading Group for Prevention and Control of Zhejiang Province and deputy director of the Provincial Health Commission, introduced it.
According to reports, huierte company 297 participants in the annual meeting, have implemented control, and completed 3 rounds of nucleic acid testing, a total of 19 positive cases were detected; the wedding banquet involved a total of 244 people, detected 11 positive cases, of which 9 were participants in the wedding, 2 people for their close contact; after the annual meeting of the enterprise, employees have taken leave to return home, and 4 cases of export cases outside the province have been found.
In addition, as of 14:00 on January 29, among the 44 locally confirmed cases reported in Hangzhou, there were 6 family cluster epidemics and 18 people, 9 people in 1 cluster epidemic in the community (Changjiang Xiyuan Community in Binjiang District), and 1 cluster epidemic in property companies with 3 people (Desheng Ginkgo Hui Property in Binjiang District).
The first confirmed case was reported in Fuyang District, Hangzhou on 28 January. On January 27, the Fuyang District Epidemic Prevention and Control Headquarters found that the ID number of a confirmed case showed that he was a Fuyang person, and immediately carried out an investigation, and soon detected a case of positive nucleic acid for the new coronavirus in Fuyang.
Infected people who attended a wedding in a certain district on January 22 introduced Gollum Global Imported Mother and Baby House, causing the bather to become infected, and the "baby bath" link became an amplifier and began to spread rapidly. As of 9:00 a.m. on February 2, a total of 10 cases of children related to the Global Imported Maternal and Infant Life Hall in Fuyang District were treated in Hangzhou. These cases bathed and played in the living hall, resulting in infection due to the closed environment and long residence time.
Fortunately, the chain of transmission of the epidemic is very clear. The case-reporting curve turns downward on the fourth day after the first case is reported. The number of new cases in a single day rose rapidly from 6 and 5 to 16 on the 30th, and the Chinese New Year's Eve (31st) day showed a turnaround and began to decline, falling to single digits on the first day of the Chinese New Year (February 1), and 5 cases were reported.

Most of the above cases have cough and sputum cough of varying degrees. The Hangzhou Municipal Health Commission has specially organized a joint expert group composed of well-known pediatric experts from the province and the city to formulate a personalized treatment plan for each child. The treatment is mainly symptomatic treatment, according to the age and condition of the child, appropriate auxiliary nebulization inhalation, nasal sprays, granules and other antiviral treatment drugs suitable for children, and as appropriate with traditional Chinese medicine treatment.
According to reports, for infants and young children under one year old, the hospital specially formulates special classes for nursing:
1. According to the different needs of the child, send the baby milk powder, bottles, diapers, etc. to the isolation ward;
2. Implement 24-hour escort for 4 infants under 1 year old, and strive to recover children through careful treatment and care;
3. Communicate with parents through WeChat videos and other means, so that parents can keep abreast of their children's treatment and rehabilitation in the hospital.
All small patients are currently in stable condition.
Across the Spring Festival, how will Hangzhou fight this anti-epidemic war?
The epidemic appeared 5 days before the Spring Festival, when the flow of people was dense, wide-ranging, and there were many uncertainties, and the epidemic prevention and control situation was complex and severe. After that, the Zhejiang Provincial Leading Group for Epidemic Prevention and Control quickly activated the emergency response mechanism, and together with Hangzhou Municipality, promoted the command and formed a joint force to quickly identify and control key areas and key personnel, quickly find the source of the epidemic transmission, cut off the transmission chain as soon as possible, and coordinate and promote the epidemic prevention and control work in the province.
Zhejiang Province urgently dispatched more than 1,100 provincial-level professionals, coordinated with relevant parties to build a temporary air film laboratory, and worked with the local government to do a good job in the demarcation of the three districts, the traceability of flow adjustment, nucleic acid sampling and testing, personnel investigation, isolation and control, environmental disinfection, case treatment and other work.
Grasping the time window, Hangzhou quickly implemented the "source inspection and control + fast sound activation + hard core isolation + precision intelligent control" mechanism to promote the implementation of the cycle of "fast detection, fast flow adjustment, fast marshalling, fast transfer, and fast isolation". Give full play to the role of nucleic acid testing in early detection, dynamically adjust the scope of the "three districts", and implement classified control measures. Accelerate the progress of tracing the source of circulation, strengthen the coordination of the "three gongs", accurately arrange the close connection and sub-close connection personnel, ensure that the first time control is in place, and resolutely prevent agglomeration and crossover.
Focusing on the Yangtze River Community in Binjiang District, Yangtze River West Garden, Ginkgo Biloba Hui, Geely Park, Gutian Global Imported Maternal and Infant Life Hall in Fuyang District, and Xianghu Wedding in Xiaoshan District, on the one hand, we will do a good job in checking and filling in the gaps, reviewing the original circulation, on the other hand, focusing on new cases, so as to achieve fast flow adjustment, fast transfer, and fast isolation.
As of 14:00 on February 1, Hangzhou had accumulated 17,023 people and 21,736 people in the second close connection, and about 10,000 risk personnel with reference to close contact and sub-close contact management. A total of 69 "three districts" have been designated in the city. In view of the prevention and control situation, the "three districts" are upgraded and managed, and the personnel in the prevention area are promoted to nucleic acid testing in accordance with the requirements of the orange code.
In view of the epidemic situation in Fuyang District, in order to block the transmission route of the virus and curb the spread and spread of the virus, in accordance with the provisions of the state, provinces and municipalities on epidemic prevention and control, from 16:30 on January 31, traffic control will be implemented on highways, national provincial highways, county and rural roads, rail transit, waterways, etc. within the administrative area of Fuyang District of Hangzhou City, and resolutely prevent risk spillover.
After the implementation of traffic control in Fuyang District, some Hangzhou citizens reflected: Why should we take vigorous control measures under the overall situation of the entire epidemic situation?
Mao Genhong, deputy secretary general of the Hangzhou Municipal Government, responded that this is mainly to prevent risk spillover, considering that the number of new cases in Fuyang District is large, Fuyang itself has a large population base, and is closely linked with surrounding districts and counties, and the flow of people during the Spring Festival is large, if there is an overflow, there will be a new epidemic risk, so in accordance with the relevant provisions of epidemic prevention and control, a traffic control decision was made for Fuyang District.
Hangzhou has daily mandatory inspections for quarantined personnel and "three districts" personnel. In order to ensure that residents in the prevention area should conduct due diligence to ensure that the relevant measures are in place after the "orange code". In addition, daily spot checks are carried out on personnel in important industries such as transportation and catering. From the perspective of social testing, as of 14:00 on February 1, Binjiang District has completed four rounds of nucleic acid testing for all employees, and Fuyang District has also carried out three rounds of social nucleic acid testing. The city has taken more than 2.529 million samples.
Centralized isolation of close, sub-close and high-risk personnel. As of 7 o'clock on February 1, more than 30,000 people were transferred in Hangzhou, of which 16,196 were transferred outside the city. In order to do a good job in ensuring the livelihood of 16,000 people quarantined in other cities, Hangzhou has sent working groups to various cities to provide good services. With the strong support of sister cities, the above-mentioned personnel have been properly resettled.
"Judging from the number of new cases in a single day, the epidemic has dropped sharply for two consecutive days, showing signs of being controlled. This fully shows that our early prevention and control strategies, policies and measures are very powerful and efficient!" Li Huanlong said on February 2.
