Beijing, May 1 The novel coronavirus pneumonia imported from Harbin and Mudanjiang in Heilongjiang province has been associated with local clustering since April 2020, especially in hospitals, which have been infected by nosocomial infections, which have lasted for a long time, and there are many cases of infection. The society will have bad effects, which will bring new pressure to consolidate not easily won epidemic prevention and control results.
The novel coronavirus pneumonia joint prevention and control mechanism comprehensive group of the State Council in April 30th will inform the following:
1、 Basic information of epidemic situation
（1） The epidemic situation of aggregation in Harbin. On April 2, a 87 year old patient, Chen Yujun, was admitted to the second hospital of Harbin City for “body temperature 37.3 ℃, right lower extremity walking procrastination and urinary incontinence for 4 days”. CT of lung in hospital showed the possibility of double pneumonia. After treatment, it did not get better. On April 6, it was transferred to the fever clinic of the First Affiliated Hospital of Harbin Medical University, and was admitted to the respiratory department. In April 9th, novel coronavirus pneumonia novel coronavirus pneumonia was found to be highly likely to be transferred to the isolation ward, and the new crown pneumonia nucleic acid detection and serological antibody test were completed. On April 10, Harbin CDC reported that the nucleic acid test was positive and diagnosed as a confirmed case, which was transferred to Heilongjiang infectious disease prevention and control hospital for treatment. Epidemiological investigation revealed novel coronavirus pneumonia among close contacts, and dozens of related cases and asymptomatic infections were confirmed. Among them, several medical workers in the hospitals mentioned above led to a new crown pneumonia epidemic.
（2） The epidemic situation in Mudanjiang city. In April 16th, novel coronavirus pneumonia suspected cases were reported in 2 cases (Gong Moulan, Wang) in Mudanjiang Kang An hospital, and the diagnosis was confirmed in April 18th. Through epidemiological investigation, nucleic acid screening was carried out for close contacts, and a number of related cases were confirmed successively, including several medical staff from Kangan Hospital of Mudanjiang City and North Hospital of Mudanjiang city.
The novel coronavirus pneumonia epidemic is caused by imported imported cases.
2、 Exposed problems
（1） Insufficient understanding of the situation of epidemic prevention and control. Harbin City and Mudanjiang City, as port cities, fail to fully understand the severe situation of “external defense input and internal defense rebound”, lack of awareness of the risk of imported epidemic, and have the feelings of war weariness and paralysis and relaxation. Relevant hospitals mistakenly believe that through customs and community prevention and control, they can completely screen out the new coronavirus infected persons, and the possibility of the occurrence of hospital clustering epidemic is very small, and there is a fluke mentality.
（2） There are weak links in pre hospital prevention and control measures. First, the entry personnel did not implement 14 days of centralized isolation management, and the “national” source epidemic control measures were not strict enough, leading to the possibility of missing detection of new coronavirus infection in the entry personnel. The preliminary results of epidemiological investigation show that the source of the epidemic in the two cities is the recent entry through the customs. Second, the community prevention and control measures have not been effectively implemented. For example, the clustering epidemic in Harbin is caused by Chen’s dinner party.
（3） Nucleic acid detection failed to be carried out in time as required. Only disease control institutions and infectious disease hospitals in Harbin can carry out the detection of new coronavirus nucleic acid, and other medical institutions fail to implement the requirements in time to strengthen the laboratory construction and carry out nucleic acid detection, and the relevant departments fail to carry out effective guidance on the work of laboratory filing of medical institutions in time, resulting in most medical institutions do not have the conditions for nucleic acid detection. In the diagnosis and treatment of fever patients, medical staff failed to strictly follow the diagnosis and treatment standards, blindly relied on clinical experience and imaging examination, failed to carry out nucleic acid detection in time, resulting in misdiagnosis and missed diagnosis.
（4） The implementation of nosocomial infection prevention and control measures is not effective. Relevant hospitals have not fully implemented the national requirements for hospital sense prevention and control. The prevention and control measures of the key departments such as pre examination triage and fever outpatient service are all in vain, and the appointment diagnosis and treatment cannot be carried out effectively, and the patients can be divided reasonably; the disinfection and isolation measures are not implemented in place, and the zoning requirements are not implemented; the ward management is seriously derelict, and no strict accompanying and visiting system has been established, and the personnel in different wards flow at will; the protection awareness of medical personnel is weak, the sensitivity is not strong, and the training is not enough In place.
3、 Next work requirements
All localities and medical institutions must learn from each other and draw lessons from each other. We should stand at the height of safeguarding people’s health rights and interests, establish the bottom line awareness, strengthen the post responsibility, and avoid the recurrence of such epidemic.
First, we should have a deep understanding of the severe situation faced by epidemic prevention and control. The novel coronavirus pneumonia epidemic prevention and control should be highly valued everywhere, and further enhance sense of responsibility and urgency, tighten the epidemic prevention and control string, and grasp the situation of prevention and control of epidemic situation. Especially in the places where the air port and land border port are located, we should always pay attention to the situation of the imported epidemic situation abroad, strictly prevent the spread of local infection, the occurrence of related cases or even the clustering epidemic situation.
Second, we will implement the requirements for the prevention and control of regular epidemics. All localities should improve and implement the regular prevention and control mechanism of timely detection, rapid disposal, precise control and effective treatment, and find and put out relevant epidemic situations together. We should further implement the requirements of early detection, early reporting, early isolation and early treatment, and do a good job in the whole chain of closed-loop management from “overseas” to “national” to “home”. Strengthen community management, reduce personnel gathering, guide scientific prevention and control, and reduce the risk of community communication.
The third is to further improve the detection ability of new coronavirus nucleic acid. On the basis of new coronavirus nucleic acid detection services provided by disease control institutions, local governments should further expand the scope of detection institutions and support and guide medical machines
