Question 1
Where did the new virus come from?
The 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, the Beijing Center for Disease Control and Prevention, said that the virus tracing in Beijing's new location is still under investigation. "Through genome-wide sequencing, it was discovered that the virus came from the direction of Europe. The preliminary judgment is related to the import. However, it is still unclear how the virus came. It may be contaminated seafood or meat, or secreted by people entering the market. Spread."
According to Wu Zunyou, chief expert in epidemiology of the Chinese Center for Disease Control and Prevention, based on preliminary knowledge and experience, there are two possibilities for the sudden emergence of a local new crown epidemic in Beijing.
The first possibility is that seafood or meat contaminated with new coronavirus 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 new crowns every day in the world. People with new crown virus 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, they will touch the contaminated products, rub their noses and rub their eyes, and they will be infected. At first, the symptoms were mild. If you didn't realize it, it might cause people to pass on 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 site. 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.
Whether contaminated seafood or meat 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.
