At 5 p.m. today, the 86th press conference on the prevention and control of the new crown pneumonia epidemic in Zhejiang Province was held.
Present at the press conference and answering reporters' questions were Sun Liming, deputy director of the Provincial Health Commission, and Jiang Jianmin, deputy director and researcher of the Provincial Center for Disease Control and Prevention. The press conference was presided over by Li Gao, deputy director of the Propaganda Department of the Provincial Party Committee and director of the Information Office of the Provincial Government.
Sun Liming, deputy director of the Provincial Health Commission, briefed on the recent outbreak of new crown pneumonia in Zhejiang.
Since 5 December, as of 3 p.m. today, a total of 138 confirmed cases and 1 asymptomatic infected person have been reported in Ningbo, Shaoxing and Hangzhou, Zhejiang. Among them, Ningbo has reported a cumulative total of 44 confirmed cases, Shaoxing has reported a cumulative report of 77 confirmed cases and 1 case of asymptomatic infection, and Hangzhou has reported a cumulative report of 17 confirmed cases.
The province has cumulatively investigated 6116 close contacts and 19311 sub-close contacts, and all of them have implemented control measures.
The three places have carried out a total of 6.1834 million nucleic acid collections, and 4.3493 million copies have been produced, except for the above-mentioned infected people, all of whom are negative.
The province has been included in the isolation and control of 484788 people, including 44,178 people in centralized isolation, 16,299 people under home health observation, and 424311 people in daily health monitoring.
A few days ago, the Provincial Prevention and Control Office issued the "Emergency Notice on Comprehensively and Strictly Strengthening the Prevention and Control of the Epidemic", which put forward seven key measures. All parts of the province should quickly implement the joint prevention and control mechanism of the State Council and the decision-making and deployment of the provincial party committee and provincial government, and implement various epidemic prevention and control measures to the letter. During the epidemic period, the general requirements are to achieve "four strict, one improvement, and two strengthening".
//
Four strict
Strictly control inter-provincial travel
Personnel in medium- and high-risk areas and the county (city, district) where they are located are strictly restricted from traveling; personnel from other counties (cities, districts) in the districted city where the medium- and high-risk areas are located do not have to travel, and those who really need to travel must hold a negative nucleic acid test certificate within 48 hours. Strictly restrict travel to medium- and high-risk areas and the county (city, district) where they are located. High-risk positions should avoid travel as much as possible, and those who really need to travel must leave their jobs for more than 14 days and hold a negative 48-hour nucleic acid test certificate, and report to their units. The above travel requirements are for inter-provincial mobility.
1
Strictly control the gathering of personnel
The province's efforts to strengthen "temperature measurement + bright code + wear masks" in public places and key places, including conference activities, gathering activities, cultural and recreational activities, etc., must be strictly controlled and continuously strengthen social control measures.
2
Strictly prevent the spillover of the epidemic
For areas where the epidemic occurs, it is necessary to scientifically and reasonably divide the scope of the control area in a timely manner, strictly implement the control measures in a classified manner, implement the "regional closure, stay at home, and provide door-to-door service" in the sealing and control area, and arrange 24-hour patrol duty; the control area implements "only in and out, people do not leave the area, and it is strictly forbidden to gather"; the prevention area implements "strengthening social control and strictly restricting the gathering of personnel". For other regions, it is necessary to strictly manage inter-provincial and inter-city travel, and strengthen the examination and approval of staff travel and the management of private travel. Since yesterday, travel agencies and online tourism enterprises in the province have suspended the operation of inter-provincial group tours and "air tickets + hotels" business.
3
Close surveillance of the outbreak
The frequency of nucleic acid testing for key personnel such as medical institutions, ports, isolation sites, and cold chains should be appropriately increased in the places where the epidemic occurs, and sampling nucleic acid tests should be carried out on schools, densely populated enterprises and institutions, and practitioners in key industries. Strengthen the management of drug sales in retail pharmacies, strengthen the management of fever diagnosis, standardize the work of epidemiological history consultation, relevant information registration, observation, nucleic acid testing, reporting and handover and referral, and strictly implement closed-loop management of fever patients.
4
One upgrade
Improve emergency response capabilities. With the help of big data and artificial intelligence means, quickly and accurately do a good job of flow investigation and personnel control, and strengthen regional investigation and landing control of risk groups. Improve the efficiency of nucleic acid testing, do a good job of organizational launch, personnel training, sampling point setting and information system support, etc., to ensure that due diligence and fast inspection should be inspected. Strictly implement the "hard-core isolation" measures, strengthen the training of staff in isolation places, standardize the internal management of isolation places, and strictly prevent cross-infection of isolated subjects.
Two reinforcements
Strengthen publicity and guidance
Further enhance public awareness of safety protection, and urge individuals to perform their civic responsibilities for epidemic prevention and control. Openly and transparently publish authoritative information and crack down on false rumors. If there are control measures such as restricting the flow of personnel, all localities should promptly release them to the outside world, and do a good job of publicizing prevention and control policies and health reminders.
Strengthen the construction of mechanisms
Strictly implement the 24-hour emergency duty and zero reporting and daily reporting systems, and supervise the implementation of the "four-party responsibility". Strict work implementation, supervision and secret visits, rectification and implementation, task sales number closed-loop management mechanism, deepen the "Internet + supervision" mechanism, to ensure that each initiative and each link of the closed loop in place, responsibility in place.
At the press conference, a reporter asked:
At present, the disease in Shaoxing, Ningbo and Hangzhou in Zhejiang is developing rapidly, and has zhejiang made any new discoveries in the detection of virus traceability? This time the virus seems to spread very quickly, so is the virus undergoing a new mutation?
Jiang Jianmin, deputy director of the Provincial Center for Disease Control and Prevention, replied:
At present, in the local cases of Shaoxing, Ningbo and Hangzhou in Zhejiang, we have carried out genome-wide sequencing and traceability detection and analysis of their viruses, and found that the viruses in the three places belong to the VOC Delta mutation AY.4 evolutionary branch, which is what we often call the Delta strain variant.
When it comes to the mutation of viruses, everyone is very concerned, but it is easy for viruses, especially RNA viruses, to mutate, which is determined by its biological characteristics. The new crown virus is also an RNA virus, so it is normal for the new crown virus to mutate, and not every mutation is developed in an uncontrollable direction.
Therefore, I also call on the majority of citizens and friends, there is no need to panic when they hear that the virus has mutated, or to believe in science.
The traceability analysis of this epidemic is the Delta variant.
The World Health Organization divides the mutation of the new crown virus into two categories, the first is the VOC mutation, which is a mutant strain that deserves attention, and the second category is VOI, which is a mutant strain to be observed.
The Delta strain is a variant that belongs to the first category and is noteworthy.
Its main feature is that more than 10 mutation sites have been generated on the spike protein of the new coronavirus, which may affect the structure of the spike protein, and then affect the spread and pathogenicity of the virus to a certain extent.
Comprehensive analysis of the prevalence of Delta mutant strains at home and abroad, we found that the delta mutant strains and the original popular strains have the following five characteristics compared with the original popular strains:
1, the spread is stronger. The Delta variant strain spreads quickly, from effective exposure to onset time is shortened, or its intergenerational transmission interval is shortened, and the average incubation period is shortened by 1 to 2 days;
2. Higher viral load. Compared with the earliest VOC alpha variant found in the United Kingdom, the CP value of the latter nucleic acid test is lower, and the lower the CP value, the higher the viral load of the patient, and the longer it takes for the nucleic acid test to turn negative;
3. More pathogenic. Delta's spread in India and the UNITED Kingdom has increased its pathogenicity. People infected with this variant have a higher rate of symptoms and a higher risk of hospitalization, and the proportion of patients who turn to severe critical illness after the onset of the disease has increased.
4. The clinical manifestations are similar. There is no significant difference between the clinical manifestations of the infected Delta strain and the clinical symptoms caused by the previous strain, and it is still manifested as fever, dry cough, fatigue, etc.;
5. There may be immune escape, but existing vaccines still have a protective effect. At present, the Delta mutation has not led to a subversive change in the biological characteristics of the new crown virus, and China's vaccine still has a protective effect, and vaccination can not only prevent infection, but also significantly reduce the risk of severe illness and death.
Therefore, this epidemic is locked as a Delta variant, although its spread has increased, we have accumulated rich experience in prevention and control in several epidemic prevention and control, and I believe that we will be able to defeat the virus.
Question: Delta strains are highly transmissible and pathogenic, what do we need to pay special attention to in terms of personal protection?
Jiang Jianmin, deputy director and researcher of the Provincial Center for Disease Control and Prevention, answered: This question is also of great concern to everyone, in view of the current epidemic of the new crown virus on the Delta variant strain, as far as the public's personal protection is concerned, we must first see that the transmission mode of the Delta variant virus has not changed, it is still respiratory droplet transmission, contact transmission and aerosol transmission, and the current vaccine still has protective power, so for us personally, the principle of protection against respiratory infectious diseases is the same. However, because the Delta strain has the characteristics of stronger transmission and pathogenicity, we the public must adhere to the following aspects at present:
First, we must overcome the paralyzing thinking to eliminate the fluke mentality, do not panic in the face of the epidemic, but have a sense of risk, always tighten the string of epidemic prevention and control, establish the concept that everyone is the first responsible person for their own health, and achieve scientific prevention and control and orderly response.
Second, we must maintain safe social distancing, wear masks, do not gather, wash hands frequently, ventilate, and consciously do a good job of personal protection. Usually pay attention to shelter when coughing and sneezing, use male spoons and chopsticks, exercise, enhance physical fitness, and develop good hygiene habits. Here I would like to emphasize that there is no gathering, and everyone can see from the transmission chain of the epidemic in our province that there are funerals, dinners, chess and card rooms, so in the current situation, we must calm down, do not gather, and do a good job of personal protection. We strive to contain the spread of the epidemic in the shortest possible time.
Third, we must pay close attention to the dynamics of the epidemic, arrange personal itineraries reasonably, recommend not going out of the province unless necessary, and avoid traveling to medium- and high-risk areas and areas with case reports. If you have been to a medium- and high-risk area or a city with a local epidemic report in the past 14 days, there is an intersection with confirmed cases or asymptomatic infected people, such as transportation or activity trajectory, and the health code appears red horse or yellow code, please report to the community at the first time, accept management, and cooperate with the implementation of relevant measures for epidemic prevention and control.
Fourth, once there is fever, dry cough, fatigue, decreased sense of smell, nasal congestion, runny nose, sore throat, conjunctivitis, myalgia and diarrhea and other symptoms, under the premise of personal protection, go to the fever clinic as soon as possible, avoid taking public transportation, when entering and leaving hospitals and other crowded places, we should cooperate with the staff to check the health code, itinerary card and other epidemic prevention measures.
Fifth, closely cooperate with epidemiological investigations, and must not deliberately conceal personal itinerary and contact history with others. A confirmed case in our province was deliberately concealed in the circulation, resulting in an asymptomatic infected person not being controlled in time, and has now been filed and investigated. Here, I also remind the broad masses of the people to cooperate conscientiously and provide true information in a timely manner.
Sixth, actively vaccinate against COVID-19 and boosters. Vaccination is the most scientific, economical and effective measure to prevent the new crown virus, and it is recommended that the public should actively receive the new crown vaccine and strengthen the needle to improve the immunization level of individuals and groups.
Seventh, do not believe in rumors, do not spread rumors, pay attention to the information and prevention and control requirements released by the government in a timely manner, and make our own due contributions to the prevention and control of the epidemic.
Question: Most of these cases in the three places in our province are caused by the gathering of people from the trajectory. Please ask, under the current epidemic situation, do we have any new management requirements for the gathering of personnel in our province?
Sun Liming, deputy director of the Provincial Health Commission, replied: Recently, the three places in our province have successively occurred local epidemics, the epidemic is fierce, the virus spreads fast, the infectivity is strong, the characteristics of aggregation are more obvious, the situation of epidemic prevention and control is complex and severe, we must strictly and fully implement the requirements for the specific management of personnel gathering put forward by the Prevention and Control Office, mainly five strict.
First, strictly control conference activities, in accordance with the principle of non-essential non-holding, online and not offline, strictly control the number and scale of conference activities, more than 50 people meeting activities, should formulate epidemic prevention and control plans, and strictly implement various epidemic prevention and control measures. Strictly control temple fairs, large-scale theatrical performances, exhibitions, promotions, and other activities, and reduce the scale and frequency of rural markets.
The second is to strictly manage party activities, promote the trend of economy, advocate the postponement of happy events and funerals, and do not hold large-scale personnel gathering activities, which must be held, reduce the scale as much as possible, advocate family dinner gatherings of no more than 10 people, and catering units that undertake banquets with more than 5 tables must strictly do a good job in epidemic prevention and control, and ensure that diners enter the dining place after implementing measures such as bright code temperature measurement. During non-dining periods, it is necessary to standardize the wearing of masks and do a good job of ventilation and disinfection of the restaurant. Organize more than 5 tables of banquets on their own, implement the regulations on epidemic prevention and control in the territory, and control the number of dine-in meals in restaurants and restaurants according to 50% of the capacity, and sit in separate seats. At the same time, guests are encouraged to pack up and take away consumption.
The third is to strictly manage literary and artistic activities, during the local epidemic in the province, all localities can combine the epidemic prevention and control situation to temporarily close indoor closed public places such as chess and card rooms, bars, KTV, mahjong rooms, board game rooms, swimming pools, etc., and tourist attractions strictly implement flow restriction reservations and staggered peak requirements. In some public places and religious places such as libraries, art galleries, museums, theaters, gymnasiums, and Internet cafes, the number of receptions must not exceed 50% of the approved number.
The fourth is to strictly manage public places, in accordance with the requirements of the health code and the linkage verification of the itinerary card, strictly abide by the middle gate of the interprovincial transportation hub, strictly manage the small door of the accommodation registration community, strictly control the key doors of medical institutions, and enter some crowded public places such as supermarkets and farmers' markets.
Fifth, strict management of key places, during the local epidemic in the province, welfare institutions, old-age service institutions, and mental health institutions implement fully enclosed management, suspend the entry and exit of visiting personnel, and advocate video visits and provide warm services for personnel in institutions. Crack down on illegal medical activities in the name of health care and health management, especially for communities where local epidemics occur, more stringent measures can be taken against personnel, the flow restriction of flow, the suspension of suspension, the closure of the closure.
In short, we must quickly tighten up and tighten up and manage it, further strictly implement the responsibilities of the four parties, resolutely overcome the lax and paralyzing thinking, the psychology of luck, and unite as one to overcome the difficulties of the times.
