On September 5th, at the press conference of the epidemic prevention and control held by the Harbin Municipal Government News Office, Wang Yan, deputy director of the Municipal Center for Disease Control and Prevention, released.

Since the local epidemic occurred on August 27, there were 69 positive infections as of 20:00 on September 5 (excluding 1 exception personnel). 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:

As of now, there are two spread chains in the city's epidemic, and the pathogens are BA.5.2 and BA.5.2.3, the pathogens of Omikon. All positive infections have epidemiological associations and clearly disseminate chains; 69 of the 69 positive infections reported, including 47 confirmed cases, accounting for 68.1%; The average incubation period of the city's this round of epidemic is 2-4 days, the shortest is 1.5 days, and the longest 1 case is more than 7 days.

Comb the cases in our city, and focus on the following cases:

On the 4th, a newly infected person had been exchanged for less than 2 minutes outdoors with the confirmed cases, causing the onset.

In this epidemic, there were 3 nucleic acid tests on the day of the infected people as negative; some members of family members had already detected the situation at the same time; infected those who were infected from exposed to positive detection for up to 7 days, especially the 5th new day. Increasing cases, on the 26th, the diners in a restaurant had been detected for 9.5 days from exposed to positive.

The case of this case shows that this time it has caused the cities in our city 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 city's epidemic risk 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.

Strengthen the sense 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".

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. Once there is a suspected new crown symptoms, it is necessary to report the first time to regulate the consultation in a timely manner.

Strictly implement the normalized prevention and control measures in 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 The "four -piece set" of epidemic prevention in public places will be implemented.

Strictly implement "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.

The Mid -Autumn Festival and the "Eleventh" holiday are coming. I hope that the general public will spend the holidays on the spot. It is not necessary not to go out. Continue to cooperate with the implementation of the epidemic prevention and control measures, strengthen confidence, and overcome the time, and work together to win the prevention and control of the epidemic.
