Multi -point+multi -chain, there are 4 spread chains in Luzhou's epidemic situation

On the evening of August 31, the Luzhou Municipal Government News Office held a press conference on preventing and controlling the emergence of the new crown pneumonia. Yu Jian, deputy secretary of the party committee of the Municipal Disease Prevention and Control Center, answered questions from reporters.

Q: What are the characteristics of this round of epidemic? What is the situation of epidemic prevention and control?

Answer: There are mainly the following features in this round of epidemic:

1. Multi -point and multi -chain exist at the same time. At present, there are 4 spread chains in this round of epidemic in our city:

The first is the infection chain of the closed -loop management personnel in Tibet, Jiangyang District, and the infection chain.

The second is the infection chain of the closed -loop management personnel after self -driving returning from Tibet, Xuyong County. The infection chain does not cause local epidemic dissemination;

Article 3 is that the out -of -provincial and external causes have discussed the return to the infection of the personnel. The infection chain causes a case of continuing infection. At present, the epidemic has no new cases for 2 days, and the risk of transmission has gradually decreased;

The fourth is that Tibet took a plane to transfer to the Internet and returned to the person infection. Because the personnel did not cooperate with the epidemic prevention and control work, and there were certain social activities, at least 7 cases of infection had been caused. The risks are still higher.

Second, strong infectious, fast transmission speed, and short intergenerational time. In particular, the fourth infection chain has at least 3 generations of infection in 4 days, and they are asymptomatic infections.

Third, the agglomeration occurs obvious. Although there are not many cases in total, at least 5 gathering epidemics, two of which are Tongqi (first and second communication chains), 2 family gathering epidemic conditions (third transmission chain and No. 1 One of the four communication chains), a gathering epidemic caused by a dinner (1 of the fourth transmission chain, and currently 4 infected people).

Based on the analysis of the above situation, the city's epidemic prevention and control situation is still relatively severe. The first two communication chains have been fully closed after reaching the rush, and the risk of transmission is low. Infection cases are gradually decreasing; but the fourth propagation chain still has a lot of uncertainty, the positive rate of environmental samples of the infected persons, the risk of communication is still large, and a certain scale of infected people may occur in the later period.
