The five cases of the infected specimens of the infected virus all -related genome sequences all belong to the BA.5.2 branch of Omikon's mutant strain.

On August 29, at the press conference of the 56th epidemic prevention and control of Harbin City, Wang Yan, deputy director of the Municipal Center for Disease Control and Prevention, introduced that on August 27, the city's newly reported local new crown lung inflammatory infection. Actively discovered after the symptoms. The new coronal virus genomic sequence belongs to the BA.5.2 of Omikon, which is the branch of BA.5. Omikon mutant BA.5 is currently the main strain that has caused the world's popularity, which has the characteristics of short latent period, strong infectious, and faster communication. BA.5.2 is the first time that the city has been detected in local cases.

After gene sequencing and flow traceability, the 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, the 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 particular, in view of the characteristics of Omikon BA.5.2, the characteristics of strong propagation and faster dissemination speed, in order to effectively control the epidemic as soon as possible, we further strictly strictly determine the close contact, appropriately expand the scope, and achieve it separated by the other way. At the same time, high, medium, and low -risk areas are defined quickly, scientific, and precise, and relevant management 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 from people". 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 according to requirements. During this time, try to reduce going out, not gathering, and not tie, and do personal protection.

During the epidemic, we also actively advocated that "citizens are the first responsible person of their own health." In particular, individuals should do self -management and health monitoring, assist in and cooperate with the epidemic prevention and control work.

First, maintain good personal hygiene habits, wearing masks, do good hand hygiene, gather less, pay attention to keeping a safe distance, and try not to go to a closed space. In particular, residents in high and medium -risk areas should maintain a good mentality, actively cooperate with the implementation of the epidemic prevention and control policy, and wait patiently to wait for the epidemic.

2. Do a good job of self -health monitoring. Once there is a suspected new crown symptoms, it is necessary to report it in time to regulate the consultation in a timely manner.

Third, reduce non -necessary going out. Try to avoid going to the place where the high -risk areas and people gather, to strengthen personal protection, and reduce the opportunity to infect Omikon variants. Actively report in advance when returning from other places, and implement corresponding measures as required.

4. Recently, there is a history of living in the epidemic -related areas, intersection with case trajectory, and abnormal people who receive health prompts and health code. Go to the nearby nucleic acid detection point as soon as possible for nucleic acid testing.
