Why is the epidemic outbreak point in the wholesale market? Where did the virus in the new development market come from?
Disease control experts : Gene discovery of emerging virus genes was from Europe
From 11 to 14 June 2020, 7 am, 51 new cases of covid were confirmed in Beijing, all of which are related to the Xinfadi Market. Among them, the information of one confirmed case is currently under investigations.
So why are wholesale markets prone to outbreaks? Where did the virus come from? What do people who have been to the Xinfadi Market recently need to do? How should people who have contact with confirmed cases be investigated? How to ensure the supply of vegetables in the Beijing market? What is the impact of upgrading 11 streets and villages in Beijing to high-risk areas in the epidemic? The Beijing News reporter sorted out the answers one by one.
Question 1
Where did the new virus come from?
Preliminary judgment is related to input, but it cannot be finalized yet
Beijing has not reported newly confirmed cases for more than 50 consecutive days. Where did the new coronavirus come from? Why did the outbreak point point to the wholesale market?
Yang Peng, Beijing CDC, said that the virus tracing in Beijing's new development site is still under investigation. "Through genome-wide sequencing, it was discovered that the virus came from the European direction, and the preliminary judgment was related to importation. However, it is unclear how the virus came from. It may be contaminated seafood or meat, or secreted by people entering the market and spread."
According to Wu Zunyou, chief expert in epidemiology of the China CDC, based on previous knowledge and experience, there are two possibilities for the sudden emergence of a local covid epidemic in Beijing.
The first possibility is that seafood or meat contaminated with SARS-CoV-2 in the wholesale market is the source. Many seafood, beef and mutton in the wholesale market are imported from abroad, including overseas imports. At present, there are more than 100,000 new cases of covid every day in the world. People with SARS-CoV-2 infection may cause pollution when handling seafood or beef and mutton. Moreover, in the wholesale market, many seafood or beef and mutton are stored frozen, in such an environment, the virus can survive for a long time.
After these products are shipped to the wholesale market in Beijing, when people in the wholesale market operate, their hands will come into contact with the contaminated products, and then rub their noses and rub their eyes, they will be infected. At first, the symptoms were mild. If you didn't realize it, it might cause people to pass on the coronavirus from work to work.
The second possibility is that there are other sources of infection. The Xinfadi wholesale market has a very large flow of people. The people in the market come from all directions, and people who enter or leave the Xinfadi wholesale market are the source of infection. For example, he may be a person who came from another epidemic source. After being infected, his symptoms were very mild, and he did not pay attention to it at the time. Since then, he has caused pollution to the new wholesale market and caused the epidemic to gather. Since several cases found so far are related to the wholesale market of Xinfadi, they turned their attention to Xinfadi.
As to whether the contaminated seafood or meat products in the market is the original source of infection, or whether people entering or leaving the market are the source of infection, both of which may exist. But according to the current situation in Beijing, the first situation is more likely.

Question 2
Is the newly confirmed case related to the new place of occurrence?
51 confirmed cases are related to Xinfadi

The spokesman of the Beijing Municipal People’s Government, Xu Hejian, said that Beijing should do a good job in tracing the source of case flow, expand the scope of flow adjustment, expand the scope of medical observation of relevant personnel, expand the scope of nucleic acid detection, and expand the scope of sampling.

They must do personal health monitoring. If symptoms have occurred, they should proceed to the nearest clinic in time, wear masks as required when going to a medical institution, and avoid taking public transportation.
