There are two spread chains in Harbin this round of epidemic situation

At a press conference on the Harbin Epidemic Prevention and Control Special Conference at the Harbin Epidemic Prevention and Control Center at the Harbin Municipal People's Government News Office on September 5, Wang Yan, deputy director of the Harbin Center for Disease Control and Prevention, issued the characteristics of the Harbin City's epidemic.

According to Wang Yan, since the local epidemic occurred on August 27, there were 69 positive infections on September 5 (excluding 1 exception personnel) as of 20:00 on September 5. The pathogen that caused this epidemic was the evolutionary branch of BA.5.2 and BA.5.2.3 of Omikon, which belongs to the sub -branch of the BA.5 evolution branch. The following features are present:

The first is that as of now, there are two spread chains in Harbin City. The pathogens are BA.5.2 and BA.5.2.3, the pathogens of Omikon. All positive infections are associated with epidemiological diseases, and the spread chain is clear;

Second, of the 69 positive infections reported, 47 of them were confirmed, accounting for 68.1%;

Third, the epidemic is obvious family, work and dining room gathering;

Fourth, the average incubation period of the Harbin outbreak is 2-4 days, the shortest is 1.5 days, and the longest 1 case is more than 7 days.

To sort out the cases of Harbin City, Wang Yan focuses on the following cases:

First, a newly added infection on the 4th had less than 2 minutes of exterior exchanges with confirmed cases, causing onset.

The second is that in this epidemic, the nucleic acid detection on the day of the infected person was negative; some members of the family had already detected the situation at the same time; New cases of daily increases were dining in a restaurant on the 26th, from exposure to positive detection of 9.5 days.

The case of this case shows that this time it has caused the Harbin outbreak strain to be contagious, and it can be spread by brief contact. Compared with the previous reported 1-7 days, the incubation period may be longer. These all suggest that the risk of Harbin epidemic still exists. Once the control requirements are relaxed, it will inevitably bring new communication risks. Remind everyone to continue to persist, actively cooperate with the implementation of various measures, and consolidate our hard -controlled prevention and control results.

1. Strengthen the awareness of prevention. Call for the general public to continue to strengthen the awareness of prevention, maintain good sanitation habits such as "diligently washing hands, one meter line, constant ventilation, and less gathering", and strictly implement the requirements of nucleic acid results, body temperature must be measured, and public places "to scan the code".

Second, do not go out, do a good job of health monitoring. Vigorously advocate that residents in the jurisdiction are unnecessary, not gathering, not gathering, no meals, and consciously bear the first responsibility of their own health, and always pay attention to personal protection. During the epidemic, we will continue to monitor self -health monitoring. Once there is a suspected new crown symptoms, it is necessary to report the first time to regulate the consultation in a timely manner.

Third, strictly implement the normalization prevention and control measures of public places. It is necessary to further standardize normalized prevention and control management during public places scan code, temperature measurement, mask, and nucleic acid detection certification inspection during the epidemic situation, and strengthen the transportation venue stations, public transportation, hotels, homestays and other accommodation places, park scenic spots, morning markets, morning markets For public places, the prevention and control measures such as "four -piece sets" of epidemic prevention are implemented.

Fourth, strict implementation of "active reporting" and "check -in." All municipal exterior returning personnel need to complete the autonomous report to the territorial communities (villages) and units 2 days in advance. After arriving at Ha, they report to the local communities (villages) and units as soon as possible, and to implement various control measures in accordance with the requirements. In the airport, railway stations, passenger stations, highway entrances, etc., are required to check for inspection, and free -ceiling nucleic acid testing is performed for free.
