Zhang Wenhong, director of the Department of Infectious Department of Huashan Hospital affiliated to Fudan University, said in a event on Friday (June 23) that the recent breakthroughs of the coronal virus are in the "family"Break out.He also said that the virus has always existed. The so -called "big epidemic is only three years" refers to the feeling that the host's immune system makes people feel.

According to Chinanews.com, Zhang Wenhong believes that for "carbon -based life", the R0 value (basic infection) of virus spread is limited. "So far, we have seen comparisonOkay, it is always in the Omikon 'family'. As long as we have cross immunity in the Omikon 'family', our original (vaccination) vaccine and previous infections have a certain role in a certain role, and we have a certain role in a certain role.. "

Zhang Wenhong said that" long new crown "is a symptom in the change.Over time, most of the symptoms of "long new crown" will become lighter and lighter, but a small number of people still feel that the symptoms are "lingering."

He explained that these problems are more complicated, and the virus has a very strong heterogeneity among different people, that is, different people (reactions) are completely different, and there is no very certain clinical clinical clinical clinical clinicalThe indicator is in line with it.

He further explained: "For example, the symptoms of a patient are very severe, and we may have no clinical indicators at all; for example, a patient is not asymptomatic, and its clinical indicators may not be very good."

Zhang Wenhong believes that over time, the "new crown" is attenuation, and "heterogeneity" is strong.

For the virus after three years, whether the virus is missing, Zhang Wenhong said that the virus has always been there.He pointed out that in the past, it was said that "the big epidemic was not three years" refers to the host's immune system that made people feel that "the big epidemic is only three years", and the virus is always there.

"Without monitoring, there is no virus. When you think there are no patients around, we can still monitor the existence of the virus." He said.

Zhang Wenhong cited a paragraph of Darwin in his speech: "The species that can survive are not the strongest, nor the smartest, but those who make a rapid response to the change."
