The novel coronavirus pneumonia cases in Harbin and Mudanjiang in Heilongjiang province since April 2020 have been associated with local clustering, especially in hospitals. The infection has been prolonged, infected with many cases and the social impact is bad. This brings new pressure to the not easily won epidemic prevention and control*prehensive group has been briefed recently. The situation is as follows:

Basic information of epidemic situation

Aggregation epidemic 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* 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.

Aggregated epidemic 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.

Exposed problems

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*munity 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.

Weak links in prevention and control measures before hospital

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*ed by Chen's dinner party.

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.
