At 21:30 on the evening of December 7, Shaoxing City held a press conference on the prevention and control of the new crown pneumonia epidemic. Responsible persons of relevant departments in Shaoxing City attended the press conference to introduce the relevant situation and answer reporters' questions. Zhejiang news client broadcast the whole process.

【21:40】Wang Hongda, Secretary of the Party Committee and Director of the Shaoxing Municipal Health Commission, introduced the epidemic situation and prevention and control work.

First, the basic situation of the epidemic situation

At 0:30 on December 7, Shangyu District of our city found a positive 1:10 mixed test sample in the daily "due diligence" nucleic acid test. After receiving the report, the epidemic prevention and control organizations at the municipal and district levels immediately launched an emergency response, isolated and observed 10 sampling objects at the first time, and organized professionals to carry out information verification, epidemiological investigation, single-person single-tube sampling and re-inspection, and implemented various epidemic prevention and control measures. At 7:00 a.m., the Shangyu District Center for Disease Control and Prevention and the Shangyu District Traditional Chinese Medicine Hospital tested 1 of them as positive for the initial screening, and the remaining 9 were negative. The Municipal Center for Disease Control and Prevention conducted a review of the samples of the initial screening positive infection, and the results were positive, and the expert group judged it to be a mildly confirmed case. After epidemiological investigation, 178 close contacts and 458 sub-close contacts have been investigated and controlled, all of which have been centrally isolated and nucleic acid sampling, and 2 cases of positive initial screening have been found.

The confirmed cases are as follows: Sun Mou, female, working in Shangpu Town Health Center, Shangyu District, currently lives in Baiguan Street, Shangyu District, as a "due diligence" personnel, has been carrying out nucleic acid testing every 2 days, until December 1 is negative. Sun Mou has not left Shangyu District of Shaoxing City since November 22, and from December 1 to 3, because of the funeral at home, he contacted relatives who participated in the funeral in other cities. At present, Sun Mou has been transferred to the Linjiang Branch of Shaoxing People's Hospital for isolation and treatment.

II. The implementation of emergency response to the epidemic situation

After the outbreak of the epidemic, the Shaoxing Municipal Party Committee and the Shaoxing Municipal Government immediately launched an emergency response, immediately organized the work of tracing the source of circulation, isolation and control, nucleic acid detection, etc., and implemented environmental sampling and testing and elimination measures for the places involved in the epidemic.

The first is to carry out traceability and control of circulation. Public security, public health, industry and information technology "three public" linkage, the city a total of 100 circulating personnel, accurately carry out epidemiological investigations, has been investigated and traced to 178 close contacts, 458 close contacts, has been all controlled. For close contacts and sub-close contacts out of the outflow city, 66 co-investigation letters have been issued, notifying the territories to implement control. Combining traditional epidemiology and laboratory epidemiology, this strain was preliminarily detected by the laboratory of the Municipal Center for Disease Control and Prevention as a VOC/delta strain of the recent cluster outbreak outside the province.

The second is to quickly carry out nucleic acid screening. As of 21:00 on December 7, 167 people had been detected as a result, of which 2 were initially positive. At the same time, nucleic acid screening has been carried out on the personnel involved in Sun's life and work, and 20343 samples have been taken, and 9847 test results have been obtained, all of which are negative.

The third is to standardize the implementation of isolation treatment. The confirmed patients have been transferred to the Linjiang Branch of Shaoxing People's Hospital for isolation and treatment through a closed loop of negative pressure ambulance, and in accordance with the latest national diagnosis and treatment plan, isolation treatment has been standardized.

3. Delineation of risk levels

Combined with the current epidemiological investigation, according to the judgment of provincial and municipal experts, the Sunshine Holiday Community and Huawei Apartment of Xingguang Community in Baiguan Street, Shangyu District were classified as medium-risk areas.

In the next step, the city will strictly implement the corresponding prevention and control measures in accordance with the national and provincial prevention and control requirements, consolidate the "four-party" responsibility of the territory, department, unit and individual; concentrate the city's strength, under the guidance of provincial experts, further carry out epidemiological investigation and traceability, strengthen closed-loop control measures for medium and high-risk groups such as close connection, sub-close connection, and spatio-temporal concomitant, and at the same time we will carry out whole gene sequencing of the virus to verify the relevance of the recent epidemic situation in China. Further strengthen early warning and monitoring of medical institutions, fever clinics, and fever sentinel points to ensure that the epidemic prevention and control threshold is moved forward. At the same time, we will concentrate on doing a good job in case treatment.

The epidemic shows that the epidemic prevention and control cannot be paralyzed and slack, and we must work more precision, precision and refinement to continuously improve our emergency response capabilities. We also call on all citizens to strengthen their self-protection, do not go out unless necessary, wash their hands frequently, wear masks, gather less, maintain safe social distance, and at the same time, strengthen the management of large-scale conferences and activities, do not hold non-essential, can be online and not offline, and jointly build a solid defense line for our epidemic prevention and control. I'll stop there.
