Three outbreaks are related to seafood and the possibility of the Dalian epidemic

Wu Zunyou, chief epidemiologist at the CDC, interpreted it this way:

Dalian has more than 100 days without a new case of Crown pneumonia, judging from the time, then it must have been outside the transmission in. We analyzed the big data and did not find a definite relationship between the June outbreak in Beijing and Dalian. And whether cases imported from abroad could have been brought into Dalian during this period, big data analysis also found no such signs. It is more likely that the importation of seafood from abroad, contaminated seafood, should be more likely.

Relationship with seafood

Wu Zunyou: There is a great similarity between them, that is, related to seafood processing or sales. In fact, when the Beijing Xinfadi outbreak occurred, we associate the Wuhan South China Seafood Market at that time is also related to seafood sales area, which a series of all suggest that it has a **** the same environment, this environment is humid, the temperature is relatively low, suitable for the virus survival, as long as there is contamination, he is in the local area of the virus may be caused by the more and more accumulation, and not easy to inactivate, making the spread of the spread of these places. The risk of spreading in these places.

In fact, we have done some investigation in Beijing, especially in Xinfadi also did some simulation experiments, the experiment suggests that if the contamination in such an environment, there are some operations generated by the aerosol can make practitioners infected. After the practitioners were infected, a mixed mode of transmission was formed in the contaminated environment. Therefore, in these seafood sales and processing places, special attention should be paid to the prevention of new crown pneumonia.

To the relevant personnel recommendations

Wu Zunyou: for the staff, the most important thing is to do a good job of protection, wearing a mask is necessary to adhere to, to prevent the emergence of some of the operations such as the production of water spray, such as in the aquatic area cleanliness is not suitable for the water gun to clean; in addition, more importantly, is the management of the workplace of the market for these markets must be ventilated often to keep the air flowing.
