For the first time in Harbin, the Omikon mutant plant BA.5.2

On August 29, the reporter learned from a press conference held by Harbin that the first report case of the Harbin epidemic was discovered after the symptoms appeared. The new coronal virus genomic sequence belongs to the BA.5.2 of Omikon, which is the branch of BA.5.

"Omikon variable plant BA.5 is the main strain that is currently popular in the world. It has the characteristics of short latent period, strong infectious, faster communication speed. BA.5.2 is the first time that the city has been detected in local cases." Wang Yan, deputy director of the Harbin Center for Disease Control and Prevention.

After the gene sequencing and flow traceability, the Harbin epidemic has the following three characteristics:

First, 5 cases related to the epidemic infected with the whole genome sequence of the specimen virus all belonged to the BA.5.2 branch of Omikon's mutant strain;

Second, the epidemic shows the gathering of family, collective units and dining rooms;

Third, the infected people are diverse, the scope of activity, fast communication speed, hidden transmission channels, renewal and communication risk.

After the epidemic, Harbin City adopted a number of emergency response measures such as flow traceability, secret investigation and control, rapid development of key areas and regional nucleic acid testing in the city. In view of the characteristics of Omikon BA.5.2, the characteristics of strong dissemination and faster transmission speed, in order to effectively control the epidemic as soon as possible, Harbin further strictly strictly judged the close contact person, appropriately expanded the scope, and should be separated; At the same time, high, medium, and low -risk areas are defined quickly, scientific, and precise, and relevant control measures are implemented as required.

The first is to designate the residence and place of work as a high -risk zone, and implement the control measures such as "not leaving the house and on -site service". The residents regularly perform nucleic acid testing;

The second is to define the activities of the case as a mid -risk area, and implement control measures such as "no regions and peaks to take things". In principle, residents are home in principle. Under the premise of strictly implementing personal protection, one person can be arranged per household every day, "orderly or orderly, partitional restrictions";

Third, the districts (counties, cities), which are reported by cases, are designated as low -risk areas except high and medium -risk zones, and implement preventive measures such as "personal protection and avoiding gathering". Strengthen social control, and various types of personnel in the area carry out nucleic acid testing in accordance with the requirements. During the period, try to reduce going out, not gathering, and not tie, and do personal protection.

In response to the situation where the management and control staff had to go out, Sun Fenglong, deputy director of the Harbin Civil Affairs Bureau, said that the community of high -risk zones coordinated the arrangements for the first time, implemented a special car, and carried out personal protection throughout the process, and implemented closed -loop management. The central risk zone shall be issued by the community and a good review and registration. For residents who have the needs of the funeral ceremony, the community will do a good job with the funeral department in advance, establish a green channel for risks to meet the needs of residents and strictly prevent risk transmission. Residents in high -risk areas have a special car for special vehicles if they have the need to participate in the funeral ceremony.
