Epidemium in Huangdao District, Qingdao: It is an imported cold chain cargo infection with virus pollution, which is the same spread chain

On July 2nd, Huangdao District, Qingdao City held a press conference on epidemic prevention and control. Regarding the detailed traceability of the epidemic flow, Jiang Fachun, deputy director of the Qingdao Disease Prevention and Control Center, made an answer.

After the Huangdao epidemic on June 30, the city immediately launched the emergency response mechanism, and the first time it carried out the stagnation, follow -up, the discharge of follow -up, the sealing control, the detection of the nucleic acid, the centralized isolation, and the treatment of the treatment. Among them, flow traceability is also one of the core tasks of our epidemic disposal, and traceability can be used to better curb the epidemic as soon as possible. We carry out traceability work at the level of on -site flow, laboratory detection, and virus gene sequencing. On -site flow was found that all nucleic acid -positive infections were imported cold chain cargo special staff, and they had loaded a number of positive imported cold chain goods. Gene sequencing results show that the virus strains of all positive infections are BA. 2 branches, the results of the sample gene sequencing of the water pollution sample of the imported cold chain cargo packaging of the imported cold chain cargo are highly the same as the source. Based on this, it is determined that during the operation, the imported cold chain cargo contaminated by the virus is infected. Chain.

This epidemic shows the following characteristics:

First, the epidemic discovered early, and the epidemic disposal was timely. All positive infections were found in the routine nucleic acid test of the key personnel who should be inspected, and they were basically early infection when they were found. The second is that this epidemic occurs in a specific place, and the scope of affection is relatively limited. All positive infections are imported cold chain cargo specialty staff. Third, the epidemic shows obvious gathering. The positive infected people work together and live together, and they are closely exposed to each other, which is also in line with the propagation characteristics of the new crown virus. Fourth, the virus comes from abroad and spreads by things and people. It is determined by gene sequencing and other means to determine the same communication chain as the imported cold chain cargo, eliminating the connection with the local epidemic conditions in other regions of China.

The rapid implementation of prevention and control measures after the epidemic has laid the foundation for controlling the epidemic and exerted good results. Based on the current prevention and control situation, the infection approach comes from the imported cold chain, and the positive goods have not flowed into the market. The infected persons are early discovery. The positive cases are all imported from a company to import cold chain cargo warehouse staff. It can be determined that the epidemic risk is generally controllable, and the risk of social communication is basically eliminated. It also reminds everyone that the risk practitioners have a special working environment and the opportunity to expose infection during the work process has increased significantly. Therefore, it is necessary to pay more attention to personal protection. First of all, we must strictly abide by the requirements of epidemic prevention and conscientiously implement the requirements of self -health monitoring. Especially for inspections, the personnel should be conducted in accordance with the regulations. At the time, after the mask is wet or dirty, it should be replaced in time, and it is necessary to avoid dangerous actions such as the mask showing nose and sweat.
