[Explanation] From 00:00 to 24:00 on October 25, 137 new cases of asymptomatic infections were reported in the Xinjiang Uygur Autonomous Region (including the Xinjiang Production and Construction Corps). As of 24:00 on October 25, Xinjiang (including the Corps) had asymptomatic infections 138 cases.
What is special about this epidemic?
A reporter from China News Agency interviewed Zeng Guang, a member of the high-level expert group of the Health Commission, to interpret this.
[Explanation] Zeng Guang pointed out that there are some differences between this epidemic and the past few epidemics. First, it occurred in ethnic minority rural areas. Second, there were a large number of asymptomatic infections, but there was no confirmed case. This requires follow-up. Conduct a lot of investigation and research.

We will then look at (asymptomatic infections) where there are no confirmed cases. If there are no confirmed cases, then these (asymptomatic) cases are completely asymptomatic.
In addition, we did not do antibody testing, and the results did not come out. It was this little girl who did it. IgM and IgG (both antibodies) were negative. What kind of person is she?
Asymptomatic infection or virus carrier?
We still have to watch.
[Explanation] At present, there are no confirmed cases among asymptomatic infections. Is it because of the early detection or the weakened virus toxicity?
There are 137 new cases in one day, does it mean that the virus has increased its spread?
Zeng Guang believes that no conclusion can be drawn on these issues.
[Concurrent] Zeng Guang, member of the high-level expert group of the National Health Commission of China
It is still necessary to respect the results of actual investigations and actual analysis. Now there are some judgments.
Do genetic analysis of the virus to see what is the difference between it and past viruses, and to determine what kind of changes have taken place in it. Is the pathogenicity rate changed?
The pathogenicity rate seems to have weakened; but the transmission power seems to be very strong.
The manifestation of the virus, whether it is pathogenic or spreading, has shown a trend of diversification.
[Explanation] Zeng Guang emphasized that the most important thing is to conduct a detailed epidemiological investigation of all positive cases.

The restricted case was first discovered. A 17-year-old girl, she is the indicated case. She is certainly not the earliest case, but she was discovered. The epidemiological transmission chain in it, I think (to study) found this patient What will happen to the spread chain in the future?
Are there patients besides 138 patients?
Now we must strengthen epidemiological investigations and analyze the situation clearly. Everyone (138 people) will do it.
[Explanation] Regarding the scale of the epidemic and whether it will spread in other cities in the future, Zeng Guang said that it is still too early to judge. Only by completing the epidemiological investigation and expanding the testing work as soon as possible can we see the future epidemic. Trend.
